1·In Earth's early days, all over the planet countless photosynthetic bacteria performed photosynthesis.
在地球早期，整个星球上有无数的光合细菌在进行光合作用。
2·The answer to this riddle lies in the metabolic activity of early photosynthetic life-forms that slowly but surely transformed the chemical composition of Earth's atmosphere.
这个谜题的答案在于早期光合生命形式的新陈代谢活动，这种活动缓慢但一定改变了地球大气的化学成分。
3·That means that organisms that have this chlorophyll inside can extend their photosynthetic range for maximum use of solar energy.
这意味着含有这种叶绿素的生物可以拓宽他们的光合范围，最大限度地利用太阳能。
4·The most common by far is photosynthetic plants that capture solar energy.
最普遍的是一些吸收太阳能进行光合作用的植物。
5·The photosynthetic technique for transferring energy from one molecular system to another should make any short-list of Mother Nature's spectacular accomplishments.
从一个分子向另一个分子传递能量的光合技术是大自然母亲最引人入神的才能之一。
1·The ancestors of plants were photosynthetic single-celled organisms that gave rise to plants presumably lacked true roots, stems, leaves, and complex reproductive structures such as flowers.
植物的祖先是进行光合作用的单细胞生物，由此产生的植物可能缺乏真正的根、茎、叶和复杂的生殖结构，如花朵。
2·Photosynthetic life is impossible there because sunlight is completely absent, but life such as the microbes that flourish deep within earth may still be possible.
因为那里完全没有阳光，所以不可能有光合作用的生命，但像在地球深处蓬勃生长的微生物之类的生命可能仍然存在。
3·As summer turns to autumn, the photosynthetic process slows down as the days get both shorter and colder, which in turn leads to less chlorophyll production and the green fading to yellow.
当夏天转变成秋天时，由于白天时间变短而且天气日益变凉，这些叶子的光合作用过程减慢了。相反，这个过程导致了较少的叶绿素，绿色褪成黄色。
4·You can see the films of green photosynthetic bacteria on top of a rock and a film of white sulfide-oxidizing bacteria underneath it in the very last scene of the movie.
在视频的最后画面中，你能发现石块顶部由进行光合作用的细菌组成的绿色膜，和下部由白色硫化细菌构成的白色的膜。
5·But there's a diverse and abundant population of photosynthetic organisms, collectively called the algae, that can be induced to make the likes of olive oil, oil that can fly jet airplanes just fine.
但是有一种多样性且很丰富的光合作用生物，统称为藻类，它们可以被诱导生产类橄榄油，一种可以让喷气式飞机正常飞行的燃料。
