Question

In adult animals,            are a source of undifferentiated cells that can divide to produce cells that can specialize.

Accepted Answer

Hello everyone and welcome to today's video. So in today's video we have which of the following statements is false regarding stem cells from that. We're looking for the incorrect statement among our answer chases. So now I want you to recall from previous videos what stem cells are in order to solve the problem and in case you forgot, let me quickly help you recall with this definition. And stem cells are undifferentiated cells found in adult organisms that retain embryonic features. So because they are undifferentiated, they can become any cell types in the adult body. So keep that in mind. Remember now let's begin by answer choice C. They're found in adults but mostly retain embryonic features. Here we have this answer choice typed out. So we're going to cancel this out because we're looking for the incorrect statement and this is actually true. Then we're going to move on to answer choice B. They are ongoing sources of the differentiated cells that make up the tissues and organs of animals and plants. Since stem cells are undifferentiated, they are able to differentiate when it is needed and they may become the tissues and organs of animals and plants whenever this is necessary as they grow. So this is actually a correct answer choice. And we're going to cancel it out. Then we're going to move on to answer choice D. They help in regeneration. So if any cell tissue is lost during certain harm to the organism then these undifferentiated stem cells can differentiate into the tissue and help with the regeneration. So this is very related to answer choice B. So we're going to cancel this out as well because it is a true statement, and this all lifts us with answer choice A. There well differentiated cells that cannot differentiate anymore. Well here in our definition we have that they're undifferentiated, so this is completely incorrect, and we're going to highlight it as the final answer to our question. I really hope this video helped you and I hope to see you on the next one.
