Detailed explanation-1: -Seed coat is the outermost covering of a seed. It helps in the protection of the seed from the physical stress such as shock, temperature variations or water damage. It also helps the seed to remain dormant within the seed coat and germinates when there are favourable conditions.

Detailed explanation-2: -The outer covering of a seed is called the seed coat. Seed coats help protect the embryo from injury and also from drying out.

Detailed explanation-3: -The seed coat’s function is simultaneously to protect the embryo and to transmit information regarding the external environment. An impenetrable seed coat may help to keep the embryo safe, but at the same time it would exclude the sensing of environmental cues.

Detailed explanation-4: -In botany, seed is an undeveloped plant embryo and food reserve enclosed in a protective outer covering called a seed coat (testa). More generally, the term “seed” means anything that can be sown, which may include seed and husk or tuber.

Detailed explanation-5: -The seed coat has two layers. The outer layer is thick and known as the testa. The inner layer is thin and known as tegmen.
