Nitrogen is needed for proteins, DNA and the chlorophyll that let plants perform photosynthesis.

氮是蛋白质、DNA和让植进行用叶绿素所必需。

To understand why, think back to photosynthesis and chlorophyll.

想知道为什么，请回想一下用和叶绿素。

It would have needed sunlight for that so that photosynthesis could begin.

它需要阳，这样才能进行用。

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

整个植都在做用，所以它长得很快。

So these orchids, they don't even make green leaves to photosynthesize.

这些兰花，它们甚至长绿叶来进行用。

Zooxanthellae supply their coral hosts with food, which they produce through photosynthesis.

虫黄藻通过用来成食，并将其贡献给珊瑚宿主。

With artificial photosynthesis, maybe we can split water molecules to make fuel like a plant.

通过人工用，也许我们可以分裂水分子，像植一样制造燃料。

Photosynthesis produced a waste product, oxygen, which was poisonous to the first organisms on Earth.

用产了一种“废”——氧气，它对地球上最初体来说是有毒。

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

多亏了植和进行用细菌，我们大气中充满了碳水化。

Photosynthesis ground to a near halt in the trees facing the artificial heat wave.

在面对人工热浪树木中，用几乎停滞。

They're cyanobacteria. They're green. They photosynthesize. They need light, but they also need water.

它们是蓝细菌它们是绿色，能进行用。它们需要，当然也需要水。

Phytoplankton's massive photosynthetic blooms produce as much as half of Earth's oxygen.

浮游植大量用产了地球上一半氧气。

To understand the new breakthrough, it is important to know how photosynthesis works.

要想理解这个新突破，重点要了解用如何运。

I mean, green photosynthesis accounts for more than 99.9% of the natural productivity on Earth.

绿色用在地球自然产力占比超过 99.9%。

This is perfect for photosynthesis and photosynthesis is dope, Hello phytoplankton productivity!

这非常适用，而用又是兴奋剂，您好，浮游植产力！

Photosynthesis takes sunlight and stores solar energy in chemical bonds.

用吸收了太阳能并把它存储在化学键中。

You see in the fall leaves stop their food making process and the chlorophyll declines.

你看，在秋天，树叶用减弱，叶绿素减少。

Instead, they modified the DNA in the chloroplasts-organelles responsible for photosynthesis, not reproduction.

相反，他们修改了叶绿体中DNA，叶绿体是负责用而是繁殖细胞器。

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

之后，珊瑚礁体内共藻类，也就是进行用食工厂，会抛弃珊瑚。

Organisms that photosynthesize at the surface take carbon dioxide out of the atmosphere.

在地表进行用将二氧化碳排出大气。
