DRAW IT From memory, draw two eukaryotic cells. Label the structures listed here and show any physical connections between the internal structures of each cell: nucleus, rough ER, smooth ER, mitochondrion, centrosome, chloroplast, vacuole, lysosome, microtubule, cell wall, ECM, microfilament, Golgi apparatus, intermediate filament, plasma membrane, peroxisome, ribosome, nucleolus, nuclear pore, vesicle, flagellum, microvilli, plasmodesma.

Welcome back. The next question asks which of the following correctly matches the eukaryotic cell organelles in the image. So let's look at this image here, we have our cell with three different organelles labeled. And one good thing to look at as we might recall from the content. Video on organelles cell organelles is that we should identify which whether this is an animal cell or a plant cell because they have different kinds of organelles, not all of them are common to both. So we can see that this is an animal cell because it doesn't have the rigid cell wall or the large vacuole you'd see in a plant cell so that can help us to know which things we should not expect to see in this cell and which we should. So this question now is actually an example of why it's a good idea and a multiple choice question to always glance down at your answer choices and see if some can get eliminated. Um Right off the bat, looking at it from something obvious. And when I do look over them, I see that choice. A One of the options is a chloroplast. Well chloroplasts are only found in plant cells, that's where photosynthesis takes place. So we can see that choice A cannot be correct because this is an animal cell. Let's keep on looking down and we see that indeed in choice B we've also got a chloroplast again and in choice D. So just by looking over our answers and recognizing this as an animal cell, we are down to only one option for our correct answer. C. So if we wanna test that, be the end of the story. But just to be thorough let's look through and make sure this is correctly labeled. And so we'll look up at our cell here. Choice A. We see these small organelles with inner membrane folds here and that's a pretty classic shape for mitochondria. And then Choice C. And B. Well we see sort of similar sort of structures see around the nucleus with the little dots on it. So see here is going to be our endo plas Mick particular. Um those little dots being the ribosomes and we have them proteins being synthesized and packaged and transported then be further out from the nucleus. Here is our Golgi apparatus, another part of the endo membrane system where proteins get further package labeled and sorted ready to be transported where they're going. And we see it surrounded by the little vesicles that bring proteins and lipids to that golgi apparatus. So let's double check choice see indeed it says a mitochondria be Golgi apparatus and siendo plasma particular. Um So C does have the correctly labeled organelles. See you next time
