The Organelle Hunter!

G'Day! [Music] - Hungry Like the Wolf by Duran Duran Howdy! I'm Über, and I'm gonna be giving you guys a tour of a eukaryotic cell. C'mon! Alright. So what we got here is the selectively permeable plasma membrane. Plasma membrane encompasses all cells, both prokaryotic and eukaryotic and it's a lipid bilayer with channel proteins dispersed throughout. Now, we're gonna try to get through the membrane with passive diffusion but we might not be able to; we're pretty big molecules. Too big molecules, mate. We're gonna have to find a channel protein to go through. Let's go! We've found a channel protein, and once we go through here it'll take us right to the center of the cytoplasm. We'll see what organelles we can find. Oi, there's a lysosome! It's job is to get waste out of the cell. Careful though, you don't want to get too close. See, if you don't have proper protection like a 5' cap or poly-A tail, he could break ya down Well, that certainly was a good first find ***'nit? But, I think there might just be an even better find right around the corner here. Crikey! Th-there's a nucleus! No, don't be frightened, I'm just giving a tour of the cell! I'm just here to observe. Okay. Why don't ya give us a rundown of what your niche in the habitat would be? Okay. [Rapping] The nucleus contains chromatin it holds the genetic information surrounded by the nuclear envelope to see it you would need, an electron microscope The nucleus is the brain of the cell it is the most important organelle. You'd find me in all the eukaryotes Muscle cells do, contain the most. Hi, I'm a vacuole. I'm basically a membrane-bound, big, empty, blob of space within a cell. I contain organic molecules including enzymes I also contain waste products, and I maintain hydrostasis/turgor within the cell. Well, we got ourselves quite a strange sight here. Uh, It's a centrosome, and if I knew anything about it I'd tell ya. But the trouble is, well, we don't. Oh, hi! I'm the centrosome, and my job i- L-let-let's go over here to find a more interesting organelle. I'm gonna go and check the endoplasmic reticulum. There's ribosomes in here usually. Crikey, there's one now! It's a ribosome, I knew we'd find one! It's startin' its protein synthesis now; findin' tRNA to build a polypeptide chain. What we have here is a mitochondria. He's the powerhouse of the cell, so it's not surprising to see him working like this. Now, his job is to take oxygen and break it down into ATP, which is the cell's power source. Hey! He's not gonna talk to me. Ya see, he's always been different from the other organelles. Some say... Some say that he's even a prokaryote that was swallowed up by a eukaryotic cell a long while ago, and never was the same. You gonna talk to me or what? I'm running the electron transport chain, and I'd like to keep doing it if you wouldn't keep bothering me. Crikey, we better give that bloke some room. Hello, I'm found in plant cells. I conduct photosynthesis. I take in light energy and use it to make organic materials like sugar and oxygen for the cell. I'm green because I contain chlorophyll. Och, here's a golgi apparatus! These guys are responsible for synthesizing, and exporting waste out of the cell. Hey, Golgi! Why don't you tell us what you're doing there? I'm just synthesizing. Getting some work done! Well there ya have it. Good day's journey inside eukaryotic cell number 13. We learned a lot, saw some great organelles, and even cameo appearances from plant cell organelles we didn't think we would see. Now, remember, this is a eukaryotic cell, not a prokaryotic one. If it would have been a prokaryotic one, we wouldn't have seen things like a nucleus or mitochondria. But, that's next year's special. For now, this is Über the Organelle Hunter saying, "See ya!"
