Match the cellular structures to their functions. Many statements will be used more than once; some structures may be matched to more than one functional description.

Question

Table matching cellular structures like ribosome and flagella to their respective functions such as motility and protection.

Accepted Answer

Hey, everyone. Let's take a look at this question together, choose which of the following is correctly matched. And here we have four different answer choices. Three of which contain a structure followed by a description of that structure that we have to determine which of the following description is correctly matched to the appropriate structure. Is it answer choice. A the cell wall is the innermost covering of a prokaryotic cell. Answer choice B the nuclear membrane is a double layer that encloses a cell's nucleus. Answer choice C A plasma membrane is the membrane found uniquely in plant cells or answer choice D. All of the above, let's work this problem out together to try to figure out which of the following answer choices contain a correct match. So starting off with answer choice A which says that the cell wall is the innermost covering of a prokaryotic cell. Well, we can recall that the cell wall refers to the layer that surrounds some cell types and is found immediately outside of the cell membrane. And since it is the layer that is found immediately outside of the cell membrane, it would not be that innermost covering of a prokaryotic cell. So that makes answer choice. A an incorrect match. So answer choice A cannot be the correct answer. And since we are looking for which of the following is correctly matched answer choice D all of the above is no longer a viable answer choice. So it can be eliminated as well. Next, we have answer choice B which says that the nuclear membrane is a double layer that encloses a cell's nucleus. Well, we can recall that the term nuclear membrane refers to the double layer that encloses the cell's nucleus. And it is where the chromosomes reside. And we can see that from answer choice B which says that the nuclear membrane is a double layer that encloses a cell's nucleus. We can identify answer choice B as being a correct match. Since the nuclear membrane is that double layer that encloses the cell's nucleus as it serves to separate the chromosomes from the cell's cytoplasm and other contents. So answer choice B is correctly matched, making answer choice B the correct answer. And lastly, we know that answer choice C is incorrect as answer choice C does not contain a correct match. As it says that the plasma membrane is the membrane found uniquely in plant cells, which we know the plasma membrane is the membrane found in all cells that separates the interior of the cell from the outside environment. So it would not be found uniquely in plant cells as it is found in all cells. So answer choice C is incorrect. I hope you found this video to be helpful. Thank you and goodbye.
