Question

State the role of endosperm in mature albuminous seeds.

Answer 1

The endosperm stores food for the egg and seedling as they grow in mature albuminous seeds. It stores nutrients like starch, proteins, and lipids, which give energy to the growing egg as it germinates. The growing embryo slowly eats the endosperm as it grows. This helps the seedling get established until it can photosynthesise and make its own food.
