HORTICULTURE

Detailed explanation-1: -The outer covering of the seed is known as the seed coat. It develops from the integument of the ovule. The outer layer is called testa and the inner layer is called tegmen. The seed coat protects the seed and its other parts.

Detailed explanation-2: -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-3: -seed development … form the seed coat (testa). The product is a structure in which the embryo is protected from temperature extremes by its state of desiccation and is often guarded from further drying and from mechanical or biological degradation by the seed coats.

Detailed explanation-4: -No Life without Protection. In many seeds, the epidermal layer of the seed coat generates a cuticle which represents a physical barrier between the seed and its external environment.
