This question asks, which organelles are surrounded by a double membrane? so we have a lot of membrane -bound organelles, but only three of them will contain a double membrane.
00:14
So the first will be the nucleus.
00:19
And this nucleus will contain a double membrane.
00:25
And if we are to look at the membrane of the nucleus, we find that there are these channels with within that nuclear membrane, and they are known as nuclear pores that will allow the passage of mrna out of the nucleus and different proteins into the nucleus.
00:51
The second double membrane bound organelle will be the mitochondria, and the mitochondria contains an outer mitochondrial membrane and an inner mitochondrial membrane.
01:07
So here we have a mitochondria, and the inner mitochondrial membrane extends into the interior of our mitochondria, and it's quite folded, actually...
