However, in bacteria the plasma membrane has other important roles such as respiration, photosynthesis, and the synthesis of lipids and cell wall components.

除此之外，细菌质膜还有其他重要的作用，例如呼吸作用、光合作用与脂质和细胞壁成分的合成。

Plants absorb carbon from the air during photosynthesis and then return it during respiration. Animals that eat those plants also respire.

在光合作用下，植物从空气中吸收碳，后在呼吸过程中将其返回。吃这些植物的动物呼吸。

In short, as part of the process of photosynthesis plants release water vapour from their leaves into the atmosphere.

简单来说就是光合作用的一部分过程，植物将叶片中的水蒸气释放到大气中。

To understand why, think back to photosynthesis and chlorophyll.

想知道为什么，请回想一下光合作用和叶绿素。

Taking the sunlight in, and through a process known as photosynthesis they're able to transfer the sun's energy and create a chemical known as chlorophyll.

吸收光，通过光合作用的过程，它们能够转的能量并产生一种叫做叶绿素的化学物质。

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

它需要光，这样才能进行光合作用。

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

虫黄藻通过光合作用来合成食物，并将其贡献给珊瑚宿主。

What they're able to do is fascinating, they're taking the sunlight in and through a process known as photosynthesis, they're able to transfer the sun's energy and create a chemical known as chlorophyll.

它们所做的是很神奇的，主要通过光合作用吸收光线，将光能转化，并产生一种叫做叶绿素的化学物质。

Grass takes up carbon from the air by photosynthesis, then cow eat that plant and its carbon, and in the cow, that carbon is then turned into methane — which is carbon and four hydrogens — CH4.

草通过光合作用从空气中吸收碳，后牛吃植物和它的碳，在牛身上，碳被转化为甲烷——就是碳和四个氢——CH4。

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

在面对人工热浪的树木中，光合作用几乎停滞。

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

绿色光合作用在地球自生产力的占比超过 99.9%。

Photosynthesis takes sunlight and stores solar energy in chemical bonds.

的光合作用吸收了能并把它存储在化学键中。

Carnivorous plants still get most of their energy via photosynthesis, just like other plants.

和普通植物一样，食肉植物大部分能量依旧依靠光合作用来获取。

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的DNA，叶绿体是负责光合作用而不是繁殖的细胞器。

Their invention-a small biological circuit they call E-Kaia-harnesses the energy plants produce during photosynthesis.

这3位在校学生的发明是一种名为E-Kaia的生物充电器，原理是利用植物在光合作用中产生的能量。

Plants have a system called photosynthesis which provides us with oxygen.

植物有一个名叫“光合作用”的系统，它能够产生氧气。

In photosynthesis, chlorophyll absorbs energy from sunlight and creates sugar to feed the plant.

在光合作用中，叶绿素从光中吸收能量，并合成糖类供养植物。
