What do you mean by endosperm?
Endosperm, tissue that surrounds and nourishes the embryo in the seeds of angiosperms (flowering plants).
In some seeds the endosperm is completely absorbed at maturity (e.g., pea and bean), and the fleshy food-storing cotyledons nourish the embryo as it germinates..
What is the role of the endosperm?
The endosperm plays an important role in supporting embryonic growth by supplying nutrients, protecting the embryo and controlling embryo growth by acting as a mechanical barrier during seed development and germination.
Which foods are examples of endosperm?
Endosperm is the most important plant product on Earth for humans. Two thirds of all human calories come from endosperm. In one form or another cereal grains, the one-seeded fruits of grasses, which include rice, wheat, maize, rye, oats, and barley, constitute the majority of human food.
What are the types of endosperm?
The primary endosperm nucleus divides rapidly to form the endosperm tissue. The endosperm nuclei increase in size as the development proceeds. In angiosperms there are three types of endosperm development— namely, nuclear, cellular, and helobial.
What is Embryosac?
