Explanation

The outermost covering of a dicotyledonous seed is the seed coat. The seed coat has two layers, the outer testa and the inner tegmen. The hilum is a scar on the seed coat through which the developing seeds were attached to the fruit. Above the hilum is a small pore called micropyle. Within the seed coat is the embryo, consisting of an embryonal axis and two cotyledons.
