NEET BIOLOGY

Detailed explanation-1: -Seed coats help protect the embryo from injury and also from drying out. Seed coats can be thin and soft as in beans or thick and hard as in locust or coconut seeds. Endosperm, a temporary food supply, is packed around the embryo in the form of special leaves called cotyledons or seed leaves.

Detailed explanation-2: -The outer covering of the seed is known as a seed coat. It protects the embryo from drying out and from any injuries. Seed coats can be thin and soft as well as hard as in coconut shell.

Detailed explanation-3: -For example, the seed coat keeps too much water from reaching the internal seed structures, as well as prevents these structures from drying out. The seed coat also provides a degree of insulation and protection from sub-freezing temperatures.

Detailed explanation-4: -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.

Detailed explanation-5: -The seed contains the embryo of a plant. Seeds have a hard outer cover that protects the embryo inside. Cotyledons in the seed store food for the growing embryo.
