Human embryonic stem cells are capable of forming all types of cells in the human body. How are these cells similar to meristem cells in plants?

Question

Accepted Answer

Hi everyone welcome back. Here's our next question. It says cells that retain embryonic features and are capable of forming all types of cells in the human body are referred to as well. Let's look at our answer choices. We have total potent cells are cells embryonic stem cells and non potent cells. As we look over them we can eliminate two of these choices right away. The other two are going to be a little trickier. Um But Choice B tumor cells is not going to be our correct answer. Tumor cells are not capable of forming all types of cells in the human body. Um They're usually already differentiated. They are cells that are characterized by by growing and dividing out of control. They've lost something's gone wrong with the signals that tell them to stop growing and dividing so that's not our answer. And in Choice D non potent cells well cells can have different potency, the potential to become different things. Um You can have total potent cells. As we see one of those choices. Pluripotent cells, multi potent cells. Unit potent cells that can only that are already differentiated can only become one type of cell but non potent would mean they couldn't become anything. So we can rule that out right away. So we're left with choice A toady potent cells and choice C embryonic stem cells. And again we're looking for cells that retain embryonic features and are capable of forming all types of cells in the human body. Our key phrase here is all types of cells in the human body because Tony potent cells not only have the capability of becoming all types of cells in the human body but they can also become the tissues of the placenta as well, giving them the capability of developing into a complete adult organism. Choice C embryonic stem cells are pluripotent completely pluripotent. They can become any type of cell in the human body but they cannot develop into the tissues of the placenta. So since our question specifically says capable of forming all types of cells in the human body and doesn't say anything about tissues of the placenta, our answer is going to be Choice C embryonic stem cells and not choice A. Toady potent cells. So once again, cells that retain embryonic features capable of forming all types of cells in the human body are referred to as Choice C. Embryonic stem cells. See you in the next video.
