In this video, we're going to begin our lesson on eukaryotic Celia and flow gela. And so the side a skeleton, specifically, micro tubules are a major structural component of both cilia and flood gela. And both cilia and flow gela are important for providing cell movement. And they both also extend outwards from the cell surface and they are both anchored to the sell by a basal body. Now, cilia are more like short hair like structures that are going to be covering the cell. And flow gela are longer tail like structures that are going to be uh that can be distributed in different ways. Now, both cilia and flew to L. A. Are made up of long micro tubules that are together in a nine plus two arrangement. And so this nine plus two arrangement is referring to the fact that there are nine pairs of micro tubules surrounding to central micro tubules. And we'll be able to see that down below in our image. And so notice over here on the left hand side, we're showing you an image of cilia which are these short hair like projections sticking off of the surface of the cell. And we're also showing you an image of flow gela, which is a longer tail like structure. And so over here we're showing you the eukaryotic uh cilia and flow gela structure. And so you can see zooming into uh the structure here. You'll notice that there is a nine plus two arrangement. And so this nine plus two arrangement is again referring to the fact that there are nine pairs of micro tubules that are surrounding a to central micro tubules. And so these micro tubules that you see here, they project throughout the entire structure downwards as you can see here. And so this is more like a bird's eye view, looking at the very top of the cilia or flow gela. And so this here concludes our brief introduction to eukaryotic cilia and flow gela. And we'll be able to get some practice applying these concepts as we move forward. So I'll see you all in our next video.

in this video, we're going to talk about the motility of eukaryotic Celia and eukaryotic flow gela. And so again, motility is referring to the ability to be able to move and cause movement. And so cilia and flow gela have similar overall structure, but each are associated with a different type of cell movement. And so cilia are actually uh going to be associated with a movement that is similar to the movement of yours, like boat oars. And so they are going to move objects around the cell or they are going to provide cell movement for the cell itself. Now, flow gela, on the other hand, do not move like yours. Instead, they move in somewhat of a whip like fashion. And so they are going to be propelling the sell through its environment. And that propulsion is going to be powered by a teepee. Hydrologists rather than being powered by a proton motive force or a PMF. Like what pro carry attic flat gela are powered by. And so if we take a look at this image down below, notice on the left hand side, we're showing you the door like motion of the celiac. And so it's going to be moving somewhat like an or where it goes in this direction. It comes back and continuously moves like an or now the flu gela, on the other hand, which you can see over here are going to be moving in more of a whip like fashion. And so that whip like fashion is going to help propel the sell through its environment. And so this here concludes our brief introduction to how to the motility of eukaryotic cilia and flow gela. And we'll be able to get some practice applying these concepts as we move forward. So I'll see you all in our next video.
