LIFE SCIENCE

Detailed explanation-1: -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.

Detailed explanation-2: -Essentially, a seed consists of a miniature undeveloped plant (the embryo), which, alone or in the company of stored food for its early development after germination, is surrounded by a protective coat (the testa).

Detailed explanation-3: -Endosperm serves as a food supply for the embryo and seedling; depending on the species, it may be rich in oils, starch, and/or protein. In some species, the majority of the endosperm is absorbed by the developing embryo and stored in the cotyledons.

Detailed explanation-4: -A seed is a sporophyte embryo, along with its food supply, packaged in a protective coat.
