Around 1.25 billion years ago, a eukaryotic cell cannibalized another cell.

大约 12.5 亿年前，一个真核细蚕食了另一个细。

Most cells are eukaryotic — animal cells, plant cells, and fungi, etc.

大多数细是真核——动细、植细和真菌等。

Inside eukaryotic cells, you have a nucleus.

真核细中有一个细核。

Plants and animals are also both eukaryotic organisms, meaning our cells contain organelles.

植和动也都是真核，这意味着我们的细含有细器。

But the system has been altered for use in a variety of species and eukaryotic cells.

但该系统已被改造，可在许多种和真核细中使用。

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

但这些最早的真核植很快就被其他动吃掉了，并被劫持了珍贵的叶绿体，就像绿叶海天牛一。

But the basic parts of this system can be manipulated and used in a variety of eukaryotic organisms and cell types.

而且这个系统的基础部分可以被操控，并在多种真核及细中运用。

And so that's a common characteristic, this endomembrane system of all eukaryotic cells.

因此，这是所有真核细的一个共同特征，即内质网系统。

So at some point, death was invented, you know, somewhere along the eukaryotic scale.

于是，在某个时刻，死亡被创造出来了，你知道的，大概是在真核的某个阶段。

Did they have a dimorphism between prokaryotic, eukaryotic?

它们在原核和真核之间是否存在二态性？

" Diameter of a eukaryotic cell." Look at that, Soren.

" 真核细的直径" , 看看这个, 索伦。

So the biggest eukaryotic cell is our happy place in the middle.

所以最大的真核细是我们在中间的快乐地方。

And so just to point to a few things, these are mitochondria inside a eukaryotic cell.

这些是真核细内的线粒体。

So eukaryotic cells are mostly a little bit under a millimeter in length.

所以真核细的长度大多略小于一毫米。

We're back to our—to our big, big eukaryotic cell.

我们回到了我们的大真核细。

The complex cell, eukaryotic cells, which contain a nucleus and organelles that rose from simple bacterial cells.

复杂的细，即真核细，包含一个核和从简单细菌细演化而来的细器。

In fact, it's thought that the majority of eukaryotic life that lives in the deep sea has bioluminescent capabilities.

事实上，人们认为活在深海中的大多数真核都具有发光能力。

Their cells don’t have a nucleus to store DNA. All plants and animals, including us humans, are eukaryotic, though.

它们的细没有细核来储存DNA。 不过，所有植和动，包括我们人类， 都是真核的。

And so endoplasmic reticulum is just one organelle inside eukaryotic cells.

内质网只是真核细内的一种细器。

Could consciousness been like the invention of the eukaryotic cell or something like this?

意识是否类似于真核细的发明，或是与此类似的事呢？
