Video transcript

Hey everyone. Let's take a look at this question together. The endo sperm is a tissue that develops within the seeds of the majority of flowering plants following double fertilization. What is the main role of the endo sperm in the life cycle of angiosperms? So let's recall what we've learned before about the endo sperm and some of its main functions in the life cycle of angiosperms. So when we're talking about the endo sperm, we know that it provides protection. And we also note that it controls the growth of the angio sperm by acting as a barrier to prevent unwanted things from entering. And we also know that it supplies nutrients to support growth. And so basically when we say this, we are saying that the endo sperm stores food or answer Choice A to provide to the embryo in the life cycle of the angio sperm. So answer choice A. Is the correct answer because we know that the end of sperm does not develop into the embryo. And we also know that it only stores food and not water and that it has nothing to do with the mary stems because we know that it comes from another structure which leaves answer choice A as the only correct answer here, I hope you found this video to be helpful. Thank you and goodbye
