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，叶绿体是负责光合作用而不是繁殖细胞器。

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

随着时间推移，它们进化成叶绿体，也是进行光合作用细胞器。

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

今，株植物都有这样细胞，充满叶绿体和线粒体。

Chloroplasts are found only in plant cells and contain chlorophyll.

叶绿体仅存在于植物细胞，而且含有叶绿素。

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

它是利用种类似于细胞器叶绿体达成这，像植物捕捉阳光样。

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

植物细胞还包含叶绿体，里面充满了种叫做叶绿素化学物质。

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“叶绿体”完好无损。

Finally, let's look at the chloroplast.

最后是叶绿体。

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

简单植物细胞可能仅有个或两个叶绿体。

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叶绿体——它们更像是植物组成部分。你不会明白，水滴鱼。

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

这使得叶绿体能够在鼻涕虫体维持更长时间。

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叶绿体。

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

蓝藻变成了叶绿体，即今进行光合作用细胞器。

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，为叶绿体等细胞器交换提供频繁机会。

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

我们称这种 kleptoplasty 为“Klepto”，像偷窃样，“plasty”像在叶绿体中样，对吧？

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

获取叶绿体并粘在细胞部不足以进行光合作用。

But these first eukaryotic plants were soon consumed by other animals, which hijacked the precious chloroplast, just like Elysia.

但这些最早真核植物很快被其他动物吃掉了，并被劫持了珍贵叶绿体，像绿叶海牛样。

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化和吸收这些动物细胞，最终形成了叶绿体。

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，我们有这些装有叶绿体死胡同。

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

叶绿体需要藻类为它们提供动物无法提供东西。
