Explanation:

A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane.

Animal cell. And what I have on the right, this should be indicative of a plant cell. Plant cell. So let's start with the, what's outside of the cell. So we see in both of them, we see the extracellular matrix. You see on this animal or outside of this animal cell, you see all these collagen fibers and everything else, all these fibers that are holding these cells into place and allow these cells to relate to each other, and actually, depending on what's inside of it, can even help signal different things to the cells, so this is an extracellular matrix. Now when we think about the extracellular matrix for a plant cell, we also think about, there's some other components that are involved in the actual cell wall, and so the cell wall is a key difference between plant and animal cells. So, the cell wall is going to be in a plant cell. Animal cells don't have cell walls. Now, if we go one layer deeper, we get to the plasma membrane, the cellular membrane, and we see that that is common to both. The animal cell is going to have a plasma membrane and the plant cell is going to have a plasma membrane and they actually can both have tunnels from neighboring cells, or tunnels between neighboring cells. We studied that in the cell wall video for plant cells. We saw these things right over here, called plasmodesmata, And we can actually see a complete one over here, because I start to draw a little bit of an adjacent cell. Plasmodesmata. And in animal cells, the analog are gap junctions, which are still tunnels between adjacent cells. So, gap junctions. Now, plasmodesmata are much more common to a much wider category of plant cells than gap junctions but gap junctions can be very relevant in certain types of animal cells, in particular, things like heart cells, where because of gap junctions between adjacent cells, electrical signals can move through the tissue and let adjacent cells know, hey, it's time to contract in the right way, so this is still very crucial for certain types of animal cells. So now let's go a layer even deeper, and actually, before I do that, I want to reemphasize this, and I do this in almost every video. All of these membranes that we draw, either the outercellular membrane or the membranes of these organelles, these are all lipid bilayers, or phospholipid bilayers, so if I were to zoom in, right over there, on this yellow place right
