These are the user uploaded subtitles that are being translated: 1 00:00:21,730 --> 00:00:27,350 Plants have a family tree, stretching back nearly half a billion years. 2 00:00:30,530 --> 00:00:35,150 They have developed an extraordinary range of strategies to survive. 3 00:00:38,170 --> 00:00:41,050 This tree is a bristlecone pine. 4 00:00:41,510 --> 00:00:44,410 It's taken thousands of years to reach this size. 5 00:00:45,730 --> 00:00:51,470 It has seen empires rise and fall, kings, queens and presidents come and go, 6 00:00:52,310 --> 00:00:56,790 and may have seen the sun rise more than one and a half million times. 7 00:00:59,150 --> 00:01:03,310 Bristlecone pines are the oldest living things on Earth. 8 00:01:13,020 --> 00:01:16,040 Bamboo is the fastest-growing plant. 9 00:01:18,660 --> 00:01:23,120 It will be full-grown 30 metres tall in just 90 days. 10 00:01:33,150 --> 00:01:38,290 Like animals, plants are constantly competing for food... 11 00:01:40,970 --> 00:01:43,470 striving to produce offspring... 12 00:01:44,790 --> 00:01:47,650 and battling against predators. 13 00:01:55,670 --> 00:01:57,370 They will deceive... 14 00:01:58,130 --> 00:02:02,210 and in some cases, they will even hunt. 15 00:02:28,360 --> 00:02:33,020 We often don't notice such dramatic behaviour because, to our eyes, 16 00:02:33,220 --> 00:02:34,280 it happens so slowly. 17 00:02:35,065 --> 00:02:40,340 But if time is compressed and you shift perspective to the plant's point of view, 18 00:02:40,820 --> 00:02:43,440 their world comes spectacularly to life. 19 00:02:44,160 --> 00:02:49,360 The events in this woodland can build to a view of half a year in less than a minute. 20 00:03:33,870 --> 00:03:37,440 Like animals, plants need food and water. 21 00:03:50,140 --> 00:03:52,180 But what sets them apart... 22 00:03:53,180 --> 00:03:54,900 is their struggle for light. 23 00:04:06,080 --> 00:04:08,820 Plants must have light in order to grow... 24 00:04:08,821 --> 00:04:12,020 and will do anything to get as much as they need. 25 00:04:16,050 --> 00:04:20,810 The forest might appear to be the perfect place for plants to thrive. 26 00:04:22,500 --> 00:04:26,530 Yet down here, on the forest floor, is one 27 00:04:26,531 --> 00:04:26,530 of the hardest places for plants to thrive. 28 00:04:26,531 --> 00:04:28,091 One of the hardest places imaginable... 29 00:04:28,440 --> 00:04:30,850 for a young plant to begin its life. 30 00:04:33,110 --> 00:04:37,830 The canopy above is so thick... that only a little sunlight can filter through. 31 00:04:42,850 --> 00:04:46,760 For this sapling, too little light means death. 32 00:04:57,180 --> 00:05:01,100 But plants on the forest floor need not be passive. 33 00:05:08,060 --> 00:05:09,980 If the light won't come to them... 34 00:05:10,700 --> 00:05:12,700 they can go to the light. 35 00:05:18,360 --> 00:05:20,140 But they still have a problem. 36 00:05:21,830 --> 00:05:24,920 The light is 50 metres above them. 37 00:05:25,740 --> 00:05:27,720 So they must climb. 38 00:05:37,970 --> 00:05:41,050 It's much easier to use another plant as scaffolding. 39 00:05:50,730 --> 00:05:53,030 But they won't get very high... 40 00:05:53,230 --> 00:05:55,230 unless they can hold on tight. 41 00:06:00,670 --> 00:06:06,630 Like fingertips searching for a hold... this ivy's adhesive pads grip the bark. 42 00:06:08,790 --> 00:06:13,590 Instead of sticking to the trees... some climbers use sharp claws. 43 00:06:18,150 --> 00:06:21,530 The cat's claw creeper hooks its tendrils... 44 00:06:21,531 --> 00:06:25,090 into the tiniest crevices and hauls itself to the top. 45 00:06:33,330 --> 00:06:37,770 With every metre it climbs... the light gets a little stronger... 46 00:06:37,771 --> 00:06:39,370 fuelling more growth. 47 00:06:44,250 --> 00:06:46,450 This tendril of a passionflower... 48 00:06:46,970 --> 00:06:49,650 seems to flail aimlessly in mid-air... 49 00:06:49,651 --> 00:06:52,790 but in fact it's searching for an anchor point. 50 00:07:00,380 --> 00:07:05,580 Its tendril coils on itself... pulling the plant towards its support. 51 00:07:14,320 --> 00:07:16,100 In a matter of just days... 52 00:07:16,620 --> 00:07:19,020 these climbers make it to the canopy. 53 00:07:22,540 --> 00:07:25,020 Now, with light in plentiful supply... 54 00:07:25,480 --> 00:07:27,200 these plants are able to flower. 55 00:07:33,530 --> 00:07:35,580 Other plants have a different strategy... 56 00:07:35,755 --> 00:07:38,320 to find the light they need in the crowded forest. 57 00:07:42,105 --> 00:07:43,180 These are air plants. 58 00:07:44,160 --> 00:07:46,760 They grow on the upper branches of tall trees... 59 00:07:46,761 --> 00:07:49,700 and spend their whole lives basking in the light. 60 00:07:51,890 --> 00:07:54,460 But growing 50 metres above the ground... 61 00:07:54,760 --> 00:07:55,920 does have its drawbacks. 62 00:07:57,790 --> 00:08:00,080 Most plants get water and nutrients... 63 00:08:00,305 --> 00:08:01,665 through their roots in the ground. 64 00:08:03,660 --> 00:08:06,097 For an air plant... with their roots planted 65 00:08:06,109 --> 00:08:08,340 in the treetops... this isn't an option. 66 00:08:09,700 --> 00:08:11,640 But they have a solution. 67 00:08:14,580 --> 00:08:17,480 First, the bare roots... have an extraordinary ability... 68 00:08:17,481 --> 00:08:19,680 to soak up water like blotting paper. 69 00:08:22,860 --> 00:08:27,140 The slightest rain or mist... and they absorb every drop. 70 00:08:30,990 --> 00:08:33,810 They also have a way of gathering nutrients. 71 00:08:37,750 --> 00:08:42,890 Their roots trap falling leaves... which eventually rot and provide the plants... 72 00:08:42,891 --> 00:08:44,870 with their own personal supply of compost. 73 00:08:52,960 --> 00:08:57,840 20,000 different plants... orchids, bromeliads and ferns... 74 00:08:58,140 --> 00:09:00,240 have taken up this remarkable lifestyle. 75 00:09:23,630 --> 00:09:25,080 For a plant to thrive... 76 00:09:25,280 --> 00:09:27,300 it must not only get enough nutrients... 77 00:09:27,550 --> 00:09:29,860 but also the right balance of nutrients. 78 00:09:30,940 --> 00:09:36,500 The soil in this waterlogged bog... is very poor quality, lacking in nitrogen. 79 00:09:39,065 --> 00:09:40,900 But these strange plants... 80 00:09:41,300 --> 00:09:42,440 have an ingenious strategy. 81 00:09:45,010 --> 00:09:48,840 Their leaves are covered in tentacles... tipped with droplets... 82 00:09:48,841 --> 00:09:51,040 of what appears to be morning dew. 83 00:09:54,700 --> 00:09:57,981 These droplets give the plant its name... the sundew. 84 00:10:04,270 --> 00:10:07,930 They're sweet-smelling... and attractive to many insects. 85 00:10:09,930 --> 00:10:12,490 But they're also extremely sticky. 86 00:10:17,820 --> 00:10:21,540 Mosquitoes emerge in huge numbers... from the boggy water... 87 00:10:21,790 --> 00:10:23,840 and the sundews are ready. 88 00:10:55,840 --> 00:10:59,840 The sundew's tentacles... are living flypaper. 89 00:11:07,610 --> 00:11:09,970 Struggling only makes matters worse. 90 00:11:13,430 --> 00:11:17,070 With each contact... the plant tightens its grip. 91 00:11:24,570 --> 00:11:27,690 As more and more tentacles... envelop the prey... 92 00:11:27,691 --> 00:11:29,870 the droplets spread across its body. 93 00:11:33,730 --> 00:11:38,530 Eventually, the insect is smothered... and drowns in sticky fluid. 94 00:11:40,650 --> 00:11:45,350 Digestive enzymes break down the body... into a nitrogen ring... a rich meal... 95 00:11:45,351 --> 00:11:47,250 which is absorbed by the plant. 96 00:11:48,140 --> 00:11:49,710 Without animal tissues... 97 00:11:50,010 --> 00:11:51,510 this plant would not survive. 98 00:11:56,440 --> 00:12:02,120 But there's another carnivorous plant... that's an even more sophisticated predator. 99 00:12:11,280 --> 00:12:13,500 The Venus flytrap. 100 00:12:22,140 --> 00:12:25,400 Like the sundew... it makes itself very attractive... 101 00:12:25,900 --> 00:12:29,201 oozing nectar across the brim... of each leaf. 102 00:12:41,230 --> 00:12:44,990 But any visiting insect... had better watch out... 103 00:12:45,115 --> 00:12:47,230 for these six tiny hairs. 104 00:12:59,460 --> 00:13:02,120 This fly... has to tread carefully. 105 00:13:09,300 --> 00:13:11,800 If it strikes one hair... 106 00:13:13,085 --> 00:13:14,880 it can carry on feeding. 107 00:13:15,860 --> 00:13:18,280 But a timer has been set. 108 00:13:25,710 --> 00:13:30,670 A second strike in less than 20 seconds... and the fly is doomed. 109 00:13:39,930 --> 00:13:43,910 An electrical impulse is triggered... and the leaf snaps shut... 110 00:13:43,911 --> 00:13:45,230 in just a fraction of a second. 111 00:13:47,490 --> 00:13:50,470 The tips lock together... like prison bars. 112 00:13:59,300 --> 00:14:04,220 If the fly is very big or very small... it may just manage to escape. 113 00:14:05,560 --> 00:14:07,700 But most are trapped. 114 00:14:33,130 --> 00:14:35,890 Ten days later... the trap reopens. 115 00:14:39,300 --> 00:14:42,780 All that remains... is a husk. 116 00:14:43,560 --> 00:14:46,140 The plant has finished its meal... 117 00:14:46,290 --> 00:14:47,800 and resets itself... 118 00:14:48,040 --> 00:14:49,480 for its next victim. 119 00:14:53,250 --> 00:14:55,410 But there is one time of year... 120 00:14:55,660 --> 00:15:00,131 when the Venus flytrap needs... some of the visiting insects... to live. 121 00:15:00,990 --> 00:15:04,050 It needs their help... to be pollinated. 122 00:15:05,850 --> 00:15:07,290 It sends up flowers... 123 00:15:07,465 --> 00:15:11,391 on tall stems... well away from the danger... of the traps below. 124 00:15:25,580 --> 00:15:29,361 Here... insects can feed safely... on nectar. 125 00:15:31,280 --> 00:15:34,161 In return... they provide a vital service... 126 00:15:34,173 --> 00:15:36,680 carrying pollen from flower to flower. 127 00:15:41,430 --> 00:15:43,110 But the truce... 128 00:15:43,610 --> 00:15:44,670 is only temporary. 129 00:15:46,220 --> 00:15:50,271 When pollination is over... it's back to business... as usual. 130 00:15:59,290 --> 00:16:03,411 80% of plant species on Earth... have flowers. 131 00:16:05,370 --> 00:16:09,610 Flowers have just one role... to enable the plant... 132 00:16:09,760 --> 00:16:10,760 to produce offspring. 133 00:16:13,450 --> 00:16:18,470 Colour, perfume... nectar... and shape... all act to make a flower... 134 00:16:19,180 --> 00:16:20,180 irresistible. 135 00:16:21,530 --> 00:16:24,370 Sunflowers grow... to face the rising sun. 136 00:16:25,260 --> 00:16:28,890 The warmth of the rays... speeds the production of nectar... 137 00:16:28,891 --> 00:16:30,890 and this lures pollinators. 138 00:16:33,510 --> 00:16:37,590 One after another... hundreds of individual florets... 139 00:16:37,591 --> 00:16:39,370 produce pollen-covered stamens. 140 00:16:50,980 --> 00:16:54,440 And like most flowers... sunflowers... 141 00:16:54,760 --> 00:16:58,440 establish a close relationship... with animals... in order to ensure... 142 00:16:58,441 --> 00:16:59,441 their reproduction. 143 00:17:05,360 --> 00:17:11,140 As these bees busily feed on nectar... they unwittingly brush against the stamens... 144 00:17:11,141 --> 00:17:14,780 collecting pollen... and then carry it... from flower to flower. 145 00:17:19,630 --> 00:17:22,290 The sunflower... is fertilised. 146 00:17:28,360 --> 00:17:31,540 In the sun-drenched fields... of southern France... 147 00:17:31,765 --> 00:17:33,580 the flowering season is a long one. 148 00:17:34,880 --> 00:17:37,061 But not all plants... have this luxury. 149 00:17:40,290 --> 00:17:41,760 Cradle Mountain in Tasmania... 150 00:17:42,200 --> 00:17:45,340 is blasted... by bitter Antarctic winds. 151 00:17:48,520 --> 00:17:49,780 To reproduce... 152 00:17:50,515 --> 00:17:52,801 the richer honeybush... must flower. 153 00:17:54,420 --> 00:17:58,341 But the delicate parts... of the flowers risk being damaged... by the cold. 154 00:18:00,260 --> 00:18:01,580 The plant... 155 00:18:01,730 --> 00:18:03,980 appears to have... an ingenious solution. 156 00:18:06,340 --> 00:18:08,361 The flower petals... fuse together... 157 00:18:08,640 --> 00:18:12,100 forming an insulated protective case... around its stamens. 158 00:18:13,190 --> 00:18:15,400 However, this creates another problem. 159 00:18:17,255 --> 00:18:20,700 The flower case... is so well sealed... that unfortunately... 160 00:18:20,701 --> 00:18:23,000 it also keeps out pollinating insects. 161 00:18:24,860 --> 00:18:27,520 During... brief sunny spells... 162 00:18:27,720 --> 00:18:30,980 the flowers warm up... and suddenly... start producing nectar. 163 00:18:35,060 --> 00:18:37,780 This attracts a bird... the black currawong. 164 00:18:39,625 --> 00:18:43,460 It has the strength... to rip open... the flower's outer casing... 165 00:18:43,710 --> 00:18:45,120 and gets its reward of nectar. 166 00:18:46,360 --> 00:18:50,620 At the same time... it exposes the delicate stamens... to waiting insects. 167 00:18:56,640 --> 00:19:01,680 With luck... there's enough time for pollination... before the biting wind... 168 00:19:01,780 --> 00:19:02,780 kills the flowers. 169 00:19:11,120 --> 00:19:15,380 For some plants... the relationship... with their pollinators... 170 00:19:15,381 --> 00:19:16,860 is not collaborative... 171 00:19:17,860 --> 00:19:18,860 it's war. 172 00:19:21,560 --> 00:19:25,600 Butterflies... and in such numbers... would seem to be perfect pollinators... 173 00:19:25,601 --> 00:19:26,601 for any flower. 174 00:19:28,740 --> 00:19:31,334 The sandhill milkweed... blooms every 175 00:19:31,346 --> 00:19:34,501 spring... in the sandy meadows... of Florida. 176 00:19:35,780 --> 00:19:37,660 It times its flowering... 177 00:19:37,840 --> 00:19:40,540 perfectly to match the arrival... of monarch butterflies... 178 00:19:40,790 --> 00:19:42,060 migrating here from Mexico. 179 00:19:44,960 --> 00:19:47,500 The monarchs... search out milkweed plants... 180 00:19:47,512 --> 00:19:49,620 but they have something other than... 181 00:19:49,621 --> 00:19:50,900 pollination on their minds. 182 00:19:52,180 --> 00:19:54,160 Rather than collect pollen... 183 00:19:54,360 --> 00:19:57,300 this female lays her eggs... on the milkweed leaf. 184 00:20:02,170 --> 00:20:05,550 This is the only plant... the caterpillars can eat. 185 00:20:11,190 --> 00:20:16,880 But the milkweed... has a defence mechanism. 186 00:20:22,140 --> 00:20:27,660 As the caterpillar bites... into a vein... a kind of latex... swells out... 187 00:20:27,661 --> 00:20:28,700 engulfing it. 188 00:20:33,630 --> 00:20:37,190 If the caterpillar... isn't quick... it will drown. 189 00:20:38,750 --> 00:20:41,971 Or find its jaws... glued together. 190 00:20:44,170 --> 00:20:45,330 But the caterpillars... don't. 191 00:20:45,331 --> 00:20:49,010 The plant's defence... is so effective... that only one third... 192 00:20:49,011 --> 00:20:51,490 of the monarch caterpillars... make it through the first day. 193 00:20:53,970 --> 00:20:59,230 But the caterpillars... that survive... grow in size and strength. 194 00:21:07,880 --> 00:21:09,140 And they go... 195 00:21:09,240 --> 00:21:10,240 for the jugular. 196 00:21:11,380 --> 00:21:14,480 By carefully chewing... through the main vein... 197 00:21:14,481 --> 00:21:19,540 the caterpillar drains the leaf of latex... and cuts off its supply. 198 00:21:20,860 --> 00:21:23,561 The milkweed's leaf... is now defenceless. 199 00:21:23,770 --> 00:21:27,960 And the caterpillar... eats in safety... before preparing to pupate... 200 00:21:27,961 --> 00:21:29,140 into a butterfly. 201 00:21:35,740 --> 00:21:41,040 But after about ten days... it becomes clear... why the plant has endured... 202 00:21:41,041 --> 00:21:42,041 this onslaught. 203 00:21:44,420 --> 00:21:48,900 A newly hatched monarch... simply can't resist... the nectar-filled cups... 204 00:21:48,901 --> 00:21:49,901 of the milkweed flowers. 205 00:21:51,440 --> 00:21:55,720 As it moves... across the flower heads... its feet slide... 206 00:21:55,721 --> 00:22:00,701 between grooves in the petals... where the flower's pollen sacs... are waiting. 207 00:22:02,680 --> 00:22:04,100 As it flies off... 208 00:22:04,420 --> 00:22:08,280 the monarch's feet... hook out the pollen... and carry it to the next flower. 209 00:22:08,660 --> 00:22:10,840 And pollination is achieved. 210 00:22:12,785 --> 00:22:18,080 Although the milkweed... has paid a heavy price... in the end it used the monarch... 211 00:22:18,081 --> 00:22:19,081 to get its way. 212 00:22:23,790 --> 00:22:25,000 Here in Dominica... 213 00:22:25,100 --> 00:22:27,763 there's a plant... that is so manipulative... 214 00:22:27,775 --> 00:22:30,101 that it has enslaved... its pollinator. 215 00:22:32,035 --> 00:22:34,201 The bright red structures... of the Heliconia... 216 00:22:34,380 --> 00:22:35,920 are actually modified leaves. 217 00:22:40,330 --> 00:22:40,990 These... 218 00:22:41,090 --> 00:22:42,090 are its flowers. 219 00:22:43,200 --> 00:22:44,270 They may be small... 220 00:22:44,445 --> 00:22:46,570 but they play a very important role... 221 00:22:46,695 --> 00:22:49,990 keeping nectar well guarded... at the very bottom of their long stems. 222 00:22:50,340 --> 00:22:55,710 The purple-throated... Carib hummingbird... with its long, curved beak... 223 00:22:55,885 --> 00:22:59,510 is the only bird capable of reaching... this energy-rich food. 224 00:23:01,540 --> 00:23:02,250 But cleverly... 225 00:23:02,550 --> 00:23:05,790 the Heliconia rations... the amount of nectar it produces... 226 00:23:05,791 --> 00:23:07,690 to force the hummingbird... 227 00:23:07,840 --> 00:23:10,810 into returning to the flower... time and time again. 228 00:23:16,750 --> 00:23:20,940 Every time it makes a visit... it picks up more pollen... on its beak and feathers. 229 00:23:27,580 --> 00:23:29,540 The hummingbird... is like an addict. 230 00:23:29,860 --> 00:23:33,640 Not only does it never stray... but it will aggressively defend... 231 00:23:33,641 --> 00:23:34,780 the flowers from thieves. 232 00:23:36,660 --> 00:23:40,240 The plant... is the master... in this relationship. 233 00:23:42,560 --> 00:23:44,940 To ensure... it gets pollinated... 234 00:23:45,090 --> 00:23:47,981 Heliconia has made the hummingbird... its prisoner. 235 00:23:55,970 --> 00:23:59,590 The plant's problems don't end... once it's been pollinated. 236 00:24:01,770 --> 00:24:05,590 Plants need... to spread their seeds... as far away as possible... 237 00:24:05,615 --> 00:24:09,531 otherwise the adults... will be in direct competition... with their offspring. 238 00:24:11,990 --> 00:24:15,770 Here in South Africa... one flower achieves this... 239 00:24:16,020 --> 00:24:17,890 by performing a remarkable trick. 240 00:24:24,730 --> 00:24:29,450 The plant waits... dormant underground... for more than a year. 241 00:24:31,550 --> 00:24:35,530 The first heavy rains... for many months... are the trigger... 242 00:24:35,531 --> 00:24:36,830 the plant has been waiting for. 243 00:24:51,850 --> 00:24:54,790 Bronze vigia... burst into flower. 244 00:25:02,700 --> 00:25:04,800 Their timing is perfect. 245 00:25:05,300 --> 00:25:08,580 These conditions... are ideal for insects too. 246 00:25:11,220 --> 00:25:15,981 The flowers enjoy... a few days of frenzied... pollination. 247 00:25:26,980 --> 00:25:30,980 But it's not long... before the searing heat... returns. 248 00:25:31,500 --> 00:25:35,640 The flowers start to wilt... shrivel... and die. 249 00:25:40,940 --> 00:25:44,980 Bronze vigia now needs... to disperse its seeds widely. 250 00:25:45,320 --> 00:25:48,060 Yet the flowers still have... their seeds trapped inside. 251 00:25:51,000 --> 00:25:53,620 But the flower... isn't finished yet. 252 00:25:56,440 --> 00:25:59,800 There are strong winds... that blow across this landscape. 253 00:26:00,160 --> 00:26:04,640 They snap the dry dead stalks... sending each and every plant... 254 00:26:04,641 --> 00:26:08,160 cartwheeling across the ground... casting seeds as it goes. 255 00:26:35,430 --> 00:26:40,030 With the heat... threatening to dry them out... the seed's germination... 256 00:26:40,031 --> 00:26:41,230 has to be immediate. 257 00:27:01,960 --> 00:27:06,680 Deep in the forests of Borneo... some plants also use the wind... 258 00:27:06,681 --> 00:27:06,940 to disperse their seeds. 259 00:27:06,941 --> 00:27:12,761 But in a completely different way... by giving their seeds... wings. 260 00:27:16,360 --> 00:27:20,960 Some are helicopters... that twist and turn... their way down to the ground. 261 00:27:33,560 --> 00:27:36,580 But there is one... that has a design... 262 00:27:36,581 --> 00:27:40,021 that enables it to travel greater distances... than all the others. 263 00:27:43,320 --> 00:27:45,540 This is Alsomitra. 264 00:27:45,720 --> 00:27:47,000 Its football size... 265 00:27:47,140 --> 00:27:51,180 pod is packed... full of hundreds... of extraordinary seeds. 266 00:27:54,160 --> 00:27:59,500 Each is an almost... aerodynamically perfect glider... that can be supported... 267 00:27:59,501 --> 00:28:00,920 by even the slightest breeze. 268 00:28:06,080 --> 00:28:10,520 Its paper-thin... upswept wings... allow it to travel... hundreds of meters... 269 00:28:10,521 --> 00:28:11,521 through the forest. 270 00:28:33,250 --> 00:28:38,170 Once the seed hits the ground... the wings rot away... 271 00:28:39,270 --> 00:28:40,270 and starts to germinate. 272 00:28:51,750 --> 00:28:58,400 A new Alsomitra vine... starts to grow up... towards the canopy... 273 00:28:58,401 --> 00:29:01,800 and into the light... well away from its parent. 274 00:29:06,040 --> 00:29:09,040 There are other ways... to disperse seeds... 275 00:29:09,940 --> 00:29:13,480 and plants have evolved... different tactics... depending on where they live. 276 00:29:14,780 --> 00:29:18,700 In the desert of Arizona... lives a master... 277 00:29:23,560 --> 00:29:24,360 called a cactus. 278 00:29:24,410 --> 00:29:25,540 In the cool of the night... 279 00:29:25,765 --> 00:29:27,820 the cacti open... their radiant flowers. 280 00:29:39,430 --> 00:29:40,600 They are soon visited... 281 00:29:40,825 --> 00:29:42,200 by nectar-feeding bats. 282 00:29:43,580 --> 00:29:46,240 And as the bats move... from cactus to cactus... 283 00:29:47,190 --> 00:29:48,190 they pollinate them. 284 00:30:07,320 --> 00:30:10,060 Each flower... only lasts a night. 285 00:30:11,620 --> 00:30:15,840 But over three weeks... each cactus will produce... more than 200 flowers. 286 00:30:23,970 --> 00:30:28,280 Every pollinated flower... immediately begins... to form a fruit at its base... 287 00:30:28,281 --> 00:30:30,180 packed with thousands of seeds. 288 00:30:45,030 --> 00:30:47,910 The mature saguaro cacti... 289 00:30:48,160 --> 00:30:51,770 are superbly adapted... to survive out in the intense heat... 290 00:30:52,070 --> 00:30:53,210 of the Sonoran desert. 291 00:30:55,270 --> 00:30:56,510 But their seeds are delicate... 292 00:30:56,930 --> 00:31:01,051 and must find shade... or they will scorch to death... before they germinate. 293 00:31:02,070 --> 00:31:04,650 The seeds are covered... with succulent sweet flesh... 294 00:31:04,651 --> 00:31:08,270 a meal that all sorts of desert creatures... find irresistible. 295 00:31:13,480 --> 00:31:16,940 White-winged doves... are among the first... to reach the ripening fruit. 296 00:31:18,980 --> 00:31:21,440 The seeds survive... in the birds' stomachs... 297 00:31:21,965 --> 00:31:26,300 and will be carried many miles... before being deposited... in their droppings... 298 00:31:26,301 --> 00:31:28,760 their own little packet of fertiliser. 299 00:31:31,575 --> 00:31:34,320 But the cactus... doesn't just rely on birds. 300 00:31:35,600 --> 00:31:39,260 Fallen fruit... provides a bonanza... for creatures on the ground. 301 00:31:43,240 --> 00:31:46,761 Foraging ants... quickly gather seeds... and flesh. 302 00:31:47,700 --> 00:31:49,080 That's if a tortoise... 303 00:31:49,205 --> 00:31:50,205 doesn't get there first. 304 00:31:52,790 --> 00:31:56,440 The greater range of animals... the cactus can get to eat its fruit... 305 00:31:56,441 --> 00:31:59,800 the more likely the seeds within... will be carried to the perfect place... 306 00:31:59,801 --> 00:32:00,801 to germinate. 307 00:32:01,600 --> 00:32:06,860 The ants carry the seeds... underground into their nests... often excavated... 308 00:32:06,861 --> 00:32:08,060 among the roots of trees. 309 00:32:11,800 --> 00:32:14,361 The tortoise too... will head for shade. 310 00:32:14,500 --> 00:32:17,600 It spends much of its day... cooling off under trees... 311 00:32:17,800 --> 00:32:20,900 where it's sure to leave... undigested seeds in its dung. 312 00:32:26,230 --> 00:32:28,030 Now the seeds wait... 313 00:32:28,770 --> 00:32:29,770 for the rains to come. 314 00:32:42,170 --> 00:32:47,070 Of the 14 million or so seeds... a cactus produces in its lifetime... 315 00:32:47,071 --> 00:32:50,610 the chances are that only one... will develop into a plant... 316 00:32:50,860 --> 00:32:51,990 that outlives its parent. 317 00:32:54,290 --> 00:32:56,450 If it was lucky enough... to find shade... 318 00:32:56,800 --> 00:33:01,190 a seed will still take 10 years... to become a 5cm tall cactus. 319 00:33:04,850 --> 00:33:06,490 To reach the size of its parents... 320 00:33:07,270 --> 00:33:09,730 10 meters... will take at least 100 years. 321 00:33:15,340 --> 00:33:17,479 Plants can survive... in the most 322 00:33:17,491 --> 00:33:20,400 unlikely... and inhospitable places on earth. 323 00:33:21,780 --> 00:33:24,466 Here on Socotra... a remote island... in 324 00:33:24,478 --> 00:33:27,440 the Arabian Sea... the dry season is brutal. 325 00:33:29,280 --> 00:33:34,100 But this... strange tree... has a strategy to survive it. 326 00:33:38,900 --> 00:33:41,020 The dragon's blood tree. 327 00:33:45,930 --> 00:33:47,270 The key... 328 00:33:47,420 --> 00:33:48,420 to their success... 329 00:33:48,650 --> 00:33:50,270 lies in their bizarre shape. 330 00:33:51,130 --> 00:33:54,490 They live on the mountain tops... where there's little soil... 331 00:33:54,765 --> 00:33:56,831 but there are critical... compensations. 332 00:34:01,270 --> 00:34:03,150 Occasional morning mists... 333 00:34:03,350 --> 00:34:04,810 sweep across the high ground. 334 00:34:12,820 --> 00:34:17,901 The mist... condenses on the skyward pointing... waxy leaves. 335 00:34:23,160 --> 00:34:28,740 The droplets... run down to the center... of the trunk... and down to its roots. 336 00:34:33,960 --> 00:34:36,220 Water is so precious... 337 00:34:36,320 --> 00:34:37,320 that the tree... 338 00:34:37,420 --> 00:34:39,060 cannot afford to waste any. 339 00:34:43,825 --> 00:34:46,440 Drops that do escape... and fall to the ground... 340 00:34:46,890 --> 00:34:48,040 are not totally lost. 341 00:34:53,350 --> 00:34:57,110 The tree's huge... densely packed crown... 342 00:34:57,410 --> 00:34:58,910 acts as a parasol. 343 00:35:00,830 --> 00:35:05,650 It shades the ground... so effectively... it allows time for the water... 344 00:35:05,850 --> 00:35:06,970 to seep into the sand. 345 00:35:11,920 --> 00:35:16,760 And it also shades... the network of roots... that lie just under the surface. 346 00:35:19,760 --> 00:35:22,840 Another plant... shares this parched desert... 347 00:35:23,460 --> 00:35:25,340 and survives... in a very different way. 348 00:35:28,540 --> 00:35:29,930 The desert rose. 349 00:35:32,090 --> 00:35:34,050 In really harsh conditions... 350 00:35:34,150 --> 00:35:35,870 it jettisons its leaves... 351 00:35:35,970 --> 00:35:37,310 to minimize water loss. 352 00:35:39,670 --> 00:35:40,350 Strangely... 353 00:35:40,550 --> 00:35:43,051 it chooses this time... to flower. 354 00:35:44,440 --> 00:35:46,690 Its bulbous trunk... is like a barrel... 355 00:35:46,840 --> 00:35:48,550 that stores water all year round. 356 00:35:53,815 --> 00:35:54,670 It's so hardy... 357 00:35:54,820 --> 00:35:56,370 it can grow out of bare rock. 358 00:36:01,510 --> 00:36:05,891 It might seem... that conditions can't get much tougher... for the plant... than here. 359 00:36:09,500 --> 00:36:10,500 But for some... 360 00:36:10,805 --> 00:36:12,200 the conditions are even harsher. 361 00:36:16,870 --> 00:36:22,210 Six hours ago... here on the coast of Australia... this tree was high and dry... 362 00:36:22,211 --> 00:36:23,211 on a sandy beach. 363 00:36:24,410 --> 00:36:27,750 For almost all plants... salt water is lethal. 364 00:36:28,050 --> 00:36:32,860 So submersion of this tree's roots... by the tide twice a day... should kill it. 365 00:36:40,600 --> 00:36:44,141 Yet this red mangrove... is flourishing. 366 00:36:50,580 --> 00:36:55,260 The retreating tide... reveals the key... to surviving the sea's assault. 367 00:36:57,940 --> 00:37:01,800 The mangrove's roots... are covered... in warty growths. 368 00:37:03,300 --> 00:37:07,860 The growths... surround pores... that take in oxygen from the air... 369 00:37:08,035 --> 00:37:09,680 when the roots are above water. 370 00:37:14,700 --> 00:37:18,100 But the pores... become useful... in a quite different way... 371 00:37:18,101 --> 00:37:19,560 when they're submerged again. 372 00:37:25,540 --> 00:37:28,221 They allow water... into the plant... 373 00:37:28,545 --> 00:37:32,121 but filter out 99% of the salt... as it passes through. 374 00:37:36,320 --> 00:37:41,140 Any salt that gets in... is pumped into a few... sacrificial leaves... 375 00:37:41,315 --> 00:37:43,330 that turn yellow... and are discarded. 376 00:37:51,030 --> 00:37:52,830 Plants can not only cope... 377 00:37:53,310 --> 00:37:55,910 with being poisoned... parched and scorched... 378 00:37:56,360 --> 00:37:58,831 but they can also survive... being frozen. 379 00:37:59,920 --> 00:38:04,130 In the world's northern forests... the changing of the seasons... 380 00:38:04,131 --> 00:38:05,750 creates its own challenges. 381 00:38:18,660 --> 00:38:22,460 As summer moves to autumn... plants prepare themselves... 382 00:38:22,461 --> 00:38:24,380 for the toughest time of their year. 383 00:38:28,020 --> 00:38:29,360 Broadleaf trees... 384 00:38:30,920 --> 00:38:32,360 a colourful spectacle. 385 00:38:33,360 --> 00:38:37,860 But for these plants... it's the beginning... of a series of urgent... 386 00:38:37,861 --> 00:38:39,960 and drastic survival strategies... 387 00:38:40,060 --> 00:38:41,960 to cope with the coming cold. 388 00:38:43,200 --> 00:38:47,740 They begin... by pulling all the water and nutrients... within their leaves... 389 00:38:47,990 --> 00:38:49,200 back into the trunk. 390 00:38:51,930 --> 00:38:55,920 The last rays... of useful sunlight... are channelled into making... 391 00:38:55,921 --> 00:38:59,920 a sugary antifreeze... that will protect... the body of the tree. 392 00:39:03,230 --> 00:39:06,590 The green pigment... chlorophyll disappears... 393 00:39:06,690 --> 00:39:09,991 leaving purples, reds, oranges... and yellows. 394 00:39:11,830 --> 00:39:13,690 Finally, the leaves die... 395 00:39:14,090 --> 00:39:15,510 and the trees discard them. 396 00:39:23,840 --> 00:39:25,640 As temperatures drop... 397 00:39:25,890 --> 00:39:27,100 below freezing... 398 00:39:27,350 --> 00:39:30,560 the plants of broadleaf forests... settle down to hibernate... 399 00:39:30,660 --> 00:39:31,660 until spring. 400 00:39:46,170 --> 00:39:49,390 Pine trees... can survive... much colder conditions. 401 00:39:51,970 --> 00:39:56,490 They have antifreeze... in the leaves themselves... that means that they can... 402 00:39:56,491 --> 00:39:57,570 keep them all winter. 403 00:40:00,010 --> 00:40:03,670 The needle-like leaves... also have a thick waxy coating... 404 00:40:03,695 --> 00:40:06,211 that limits any water loss... through pores. 405 00:40:08,270 --> 00:40:09,690 The winters here... 406 00:40:09,940 --> 00:40:11,110 are long and hard. 407 00:40:13,310 --> 00:40:18,270 The trees have to survive... temperatures of down to... minus 40 centigrade... 408 00:40:18,271 --> 00:40:19,530 for five months. 409 00:41:06,840 --> 00:41:13,020 But one pine tree... is capable of surviving... even harsher conditions. 410 00:41:17,020 --> 00:41:20,540 These pines... live at the limit of life... 411 00:41:20,790 --> 00:41:24,260 above 3,000 meters... in the mountains of Western America. 412 00:41:26,460 --> 00:41:29,460 Almost continuous... freezing temperatures... 413 00:41:29,610 --> 00:41:31,220 and savage winds... 414 00:41:31,445 --> 00:41:32,780 make life so tough... 415 00:41:33,005 --> 00:41:34,480 that these bristle cones... 416 00:41:34,680 --> 00:41:35,980 only manage to grow... 417 00:41:36,230 --> 00:41:37,660 for six weeks of the year. 418 00:41:40,460 --> 00:41:42,900 Everything is about... conserving energy. 419 00:41:44,410 --> 00:41:46,440 They hardly ever... shed their needles... 420 00:41:46,665 --> 00:41:48,560 which can last more than 30 years. 421 00:41:51,080 --> 00:41:55,160 After centuries... of being blasted by storms... a full-grown tree... 422 00:41:55,161 --> 00:41:58,740 still survives... with only a strip of bark... a few inches wide. 423 00:42:04,310 --> 00:42:07,430 These trees live life... at such a slow pace... 424 00:42:07,755 --> 00:42:09,390 that they can reach great age. 425 00:42:09,710 --> 00:42:12,250 Some are over 5,000 years old. 426 00:42:16,350 --> 00:42:18,310 It's been said of the bristle cones... 427 00:42:18,535 --> 00:42:22,370 that to live here... is to take a very long time to die. 428 00:42:30,700 --> 00:42:34,520 As the northern spring approaches... the warming temperatures... 429 00:42:34,521 --> 00:42:37,940 and increased day length... release the land from winter. 430 00:42:44,010 --> 00:42:47,330 Plants that have... lay in dormant... begin to grow again. 431 00:42:54,800 --> 00:42:59,960 These have overwintered... buried in the mud at the bottom... of this frozen lake. 432 00:43:09,740 --> 00:43:12,940 The retreating ice... allows the water to warm... 433 00:43:13,090 --> 00:43:16,920 and this white water lily... to flourish... for another season. 434 00:43:33,690 --> 00:43:37,210 And as all the trees... come out of their winter rest... 435 00:43:37,211 --> 00:43:40,610 the vivid green of new leaves... returns to the land. 436 00:44:02,240 --> 00:44:07,820 From the frozen north... to the southern deserts... the spring bloom symbolizes... 437 00:44:07,821 --> 00:44:09,460 the success of plants... 438 00:44:09,735 --> 00:44:11,880 in surviving against the odds. 439 00:44:38,120 --> 00:44:41,020 But the most successful type... of flowering plant... 440 00:44:41,395 --> 00:44:43,360 is one that makes up 20%... 441 00:44:43,880 --> 00:44:45,620 of all plant life on the planet. 442 00:44:47,940 --> 00:44:48,940 Grass. 443 00:44:50,680 --> 00:44:53,681 There are 10,000... different species. 444 00:44:59,880 --> 00:45:03,900 Today they form the diet... of many thousands of different animals. 445 00:45:08,290 --> 00:45:12,850 And a few grasses... particularly rich in nutrients... 446 00:45:12,851 --> 00:45:16,450 have developed a relationship... with one animal... 447 00:45:16,900 --> 00:45:18,370 and together the two... 448 00:45:30,460 --> 00:45:35,140 Ten thousand years ago... we humans started to cultivate rice... 449 00:45:35,490 --> 00:45:37,900 in order to harvest... its food-rich seeds. 450 00:45:44,980 --> 00:45:49,420 Now half of the world's population... depends on it. 451 00:45:58,900 --> 00:46:00,650 But there is one other grass... 452 00:46:00,875 --> 00:46:03,510 that has spread even further... across the planet... 453 00:46:03,860 --> 00:46:05,830 due to its relationship with humans. 454 00:46:07,610 --> 00:46:08,610 Wheat. 455 00:46:13,500 --> 00:46:15,640 It underpinned the development... 456 00:46:15,890 --> 00:46:17,080 of western civilization. 457 00:46:26,800 --> 00:46:31,200 Today it covers more of the land... than any other kind of plant. 458 00:46:39,260 --> 00:46:43,480 Plants have been residents on land... longer than animals... 459 00:46:43,481 --> 00:46:46,941 and have had nearly half a billion years... to evolve. 460 00:46:50,180 --> 00:46:54,020 During that time they've diversified... into countless forms... 461 00:46:54,021 --> 00:46:56,160 and have colonized every habitat. 462 00:47:05,660 --> 00:47:08,540 This is the first time... As well as collaborating with animals... 463 00:47:08,541 --> 00:47:13,380 plants are sometimes their masters... exploiting them to their own advantage. 464 00:47:25,900 --> 00:47:31,000 Plants capture energy from the sun... and all life on land... 465 00:47:31,001 --> 00:47:33,881 directly or indirectly... depends on them. 466 00:47:34,180 --> 00:47:40,440 So ultimately... plants fuel the diversity... of life on earth. 467 00:47:50,620 --> 00:47:54,540 To see the behaviour of plants... as they struggle to survive... 468 00:47:54,541 --> 00:47:56,520 presented a unique challenge. 469 00:48:02,960 --> 00:48:08,080 The plants team... had to employ many techniques... including time-lapse... 470 00:48:08,081 --> 00:48:09,420 and high-speed photography. 471 00:48:14,240 --> 00:48:18,180 They filmed in jungles... deserts, swamps and plains... 472 00:48:18,181 --> 00:48:21,800 but they also spent many hours... shooting in a converted barn... 473 00:48:21,801 --> 00:48:23,280 just outside Exeter. 474 00:48:23,480 --> 00:48:24,680 Plants are the only animals... 475 00:48:35,510 --> 00:48:39,450 that can survive... under the watchful eye... of green-fingered cameraman... 476 00:48:39,451 --> 00:48:40,451 Tim Sheppard. 477 00:48:44,550 --> 00:48:48,630 Filming plants in time-lapse... takes so long and is so susceptible... 478 00:48:48,631 --> 00:48:53,170 to changes in light levels... and weather conditions... that some key sequences... 479 00:48:53,370 --> 00:48:54,910 had to be filmed in this studio. 480 00:49:01,530 --> 00:49:02,880 In time-lapse... 481 00:49:03,005 --> 00:49:07,300 a camera takes a series of pictures... over an extended period of time... 482 00:49:07,560 --> 00:49:10,660 so when played back... the action appears speeded up. 483 00:49:12,060 --> 00:49:17,180 These sunflowers actually take... three days to open... but are seen opening... 484 00:49:17,181 --> 00:49:18,181 in a matter of seconds. 485 00:49:23,980 --> 00:49:27,120 The most complex time-lapse... the team attempted... 486 00:49:27,121 --> 00:49:32,540 showed an entire growing season... in an English woodland... in one continuous shot. 487 00:49:32,740 --> 00:49:35,560 A shot that took two years to create. 488 00:49:47,370 --> 00:49:52,420 As the producer...
