Our atmosphere is full of it thanks to plants and photosynthetic bacteria.

多亏了植和进行光合作用的细菌，我们的大气中充满了碳水化合。

In contrast, chlorophyll fluorescence is a direct measure of photosynthetic activity.

比之下，叶绿素荧光能直接地测量光合作用活动。

The whole of the plant is pretty much photosynthetic, so it grows fast.

整个植都在做光合作用，所以它长得很快。

If not dealt with, the excess light can damage their photosynthetic machinery.

如果不解决这个问题，过量的光线会毁坏植中运行光合作用的机制。

And then, the symbiotic algae that live inside corals-which are photosynthetic food factories-abandon the corals.

之后，珊瑚礁体内的共藻类，也就是进行光合作用的食工厂，会抛弃珊瑚。

But that's just one of three ways that light entering a photosynthetic organism is used.

但是这仅仅只是光进入光合体内被使用的三种方式的其中一种。

At least 50% of the oxygen on earth is produced by photosynthetic microorganisms like algae and cyanobacteria.

地球上至少 50％ 的氧气都是由光合微，如藻类和蓝细菌产的。

Although invisible to the naked eye, phytoplankton are so abundant that they are responsible for half of all the carbon absorbing photosynthetic activity on earth.

尽管我们肉眼看不见，但是浮游植的数量太过庞大，它们承担了地球上一半的光合作用。

And here it is for the first time unveiled at TED -- our first photosynthetic wearable, liquid channels glowing with life inside a wearable clothing.

在這個TED大會上我們首次展示--我们的第一件，由有命、会成长的 液体管道构成，可行光合作用的服饰。

Too much UV can even mess up photosynthesis, because it can damage structures that help capture energy from sunlight, like important proteins, chlorophyll, or photosynthetic genes.

过多的紫外线甚至会扰乱光合作用，它会破坏绿叶中捕获阳光能量的结构，比如一些重要的蛋白质、叶绿素或者控制光合作用的基因。

And billions of years ago, these stromatolites, ancient communities of photosynthetic bacteria that are equal parts biology and geology, may have exhaled the first breaths of life-giving oxygen.

数十亿年前的这些叠层石，古老的光合细菌群落，它们在学和地质学中是一样的部分，可能已经呼出了第一口提供命的氧气。

They basically evolved as flotation devices for photosynthetic microbes that live in water and need to float to the top of the water so they can get enough sunlight.”

活在水中的光合作用微进化出这些气泡囊作为漂浮装置，以便浮出水面来获得足够的阳光。”

" The bright pink pigments are the molecular fossils of chlorophyll that were produced by ancient photosynthetic organisms inhabiting an ancient ocean that has long since vanished, " she said in a statement.

" 亮粉色色素是叶绿素分子化石，由活在早已消失的远古海洋中的光合产。"

Ferns can even thrive on a photosynthetic income that's inadequate for the small offspring of many tall trees, and thus the humble fern coexists with the tall timber above by competing on its own terms.

青苔甚至能够在不充足的光合作用下茂盛成长，谦卑的青苔可以和大树的后代并存，在与高大木材的竞争中坚固自己的地位。
