Finally, let's look at the chloroplast.

最后是绿体。

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

相反，他们修改了绿体中DNA，绿体是负责光合作用而不是繁胞器。

Chloroplasts are found only in plant cells and contain chlorophyll.

绿体仅存在于植物胞内，而且含有绿素。

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

简单植物胞可能仅有一个或两个绿体。

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

今天，每一株植物有这样胞，充满绿体和线粒体。

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

植物胞还包含绿体，里面充满了一种叫做绿素学物质。

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

随着时间推移，它们进绿体，也就是进行光合作用胞器。

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

它是利用一种类似于胞器绿体达这一目，就像植物捕捉阳光一样。

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。

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

它将胞吸空，并消耗其大部分物质，留下“绿体”完好无损。

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——它们更像是植物组部分。你不会明白，水滴鱼。

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

如此令人难以置信适应性，竟然有多达 70 多种鼻涕虫从食物中窃取绿体。

And cyanobacteria became chloroplasts, the organelles that carry out photosynthesis today.

蓝藻变了绿体，即今天进行光合作用胞器。

Tripos is in turn eaten by other mixotrophic algae, providing frequent opportunity for exchange of organelles such as chloroplasts.

角藻又被其他混合营养藻类吞食，为绿体等胞器交换提供频繁机会。

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，太阳光照射在植物胞里一些叫做绿体结构上，而这些绿体中含有大量绿素色素。

Some of these tiny plants were not digested and lived on in the animal cells, eventually giving rise to chloroplasts.

这些微小植物并无法消和吸收这些动物胞，最终形了绿体。

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

获取绿体并粘在胞内部不足以进行光合作用。

And at the end of these branches, we have these cul de sacs that are loaded with chloroplasts.

在这些分支尽头，我们有这些装有绿体死胡同。

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动物无法提供东西。

We call this kleptoplasty." Klepto" , as in to steal, " plasty" as in chloroplast, right?

我们称这种 kleptoplasty 为“Klepto”，就像偷窃一样，“plasty”就像在绿体中一样，对吧？
