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

相反，他们修改了绿体中的DNA，绿体是负责光合作用而不是繁殖的细胞器。

Over time, that evolved into a chloroplast, the organelle that does photosynthesis.

时间的推移，它们进化成绿体，也就是进行光合作用的细胞器。

Today, every single plant has cells like this, full of chloroplasts and mitochondria.

今天，每一株植物都有这样的细胞，充满绿体和线粒体。

Chloroplasts are found only in plant cells and contain chlorophyll.

绿体仅存在植物细胞内，而且有绿素。

It does so using a chloroplast-like organelle, like the one plants use to capture sunlight.

它是利用一种类似细胞器的绿体达成这一目的，就像植物捕捉阳光一样。

Plant cells also contain chloroplasts which are filled with a chemical called chlorophyll.

植物细胞还绿体，里面充满了一种叫做绿素的化学物质。

Finally, let's look at the chloroplast.

最后是绿体。

Simple plant cells may have only one or two chloroplasts in them.

简单的植物细胞可能仅有一个或两个绿体。

You won't find chloroplasts in animals — they're more of a plant thing. You wouldn't understand, Blobfish.

你在动物身上找不到绿体——它们更像是植物的组成部分。你不会明白的，水滴鱼。

During this process, sunlight hits structures within a plant's cells called chloroplasts, which are packed with chlorophyll pigments.

在光合作用中，太阳光照射在植物细胞里一些叫做绿体的结构上，而这些绿体中有大量的绿素色素。

It sucks the cell empty and digests most of its contents, but the chloroplasts remain intact.

它将细胞吸空，并消耗其大部分物质，留下“绿体”完好无损。

This makes the chloroplasts able to sustain themselves for longer inside the slug.

这使得绿体能够在鼻涕虫体内维持更长时间。

Plants do this by using organelles called chloroplasts, which give them their bright colors and convert sunlight into food through photosynthesis.

植物通过“绿体”的细胞体实现上述功能，“绿体”赋予它们鲜亮的颜色，并通过光合作用将阳光转化为食物。

As incredible as this adaptation is, there are more than 70 species of slug that steal chloroplasts from their food.

如此令人难以置信的适应性，竟然有多达 70 多种鼻涕虫从食物中窃取绿体。

Taking a chloroplast and sticking inside of a cellis not enough to become photosynthetic.

获取绿体并粘在细胞内部不足以进行光合作用。

Chloroplasts engage in photosynthesis and are restricted to algae and plants.

绿体进行光合作用，仅存在藻类和植物中。

And we think chloroplasts got into plant cells in the same exact way.

我们推测绿体也是以同样的方式进入植物细胞的。

Chloroplasts need things that the algae provide to themthat animals shouldn't be able to do.

绿体需要藻类为它们提供的动物无法提供的东西。

So these are the mitochondria and the chloroplasts.

这些就是线粒体和绿体。

A chloroplast is the part of a plant cell where photosynthesis takes place, converting sunlight into food.

绿体是植物细胞中进行光合作用的部分，能将阳光转化为食物。
