The ovule wall, which is made up of maternal cells called integument tissue, matures to become the seed coat. An example of a seed coat is the red or tan "skin" on a peanut. The ovary wall (note the important difference between the words "ovule" and "ovary") matures into the protective cover called the pericarp.

The following are some important structures of a bean seed: Testa - The term testa refers to the outermost protective layer, which is often extremely thin but resilient. Water can penetrate the testa's surface through a microscopic opening known as the micropyle and begin the germination process, thus breaking the latent period. Cotyledons.

Seed Growth. In angiosperms, the process of seed development begins with double fertilization and involves the fusion of the egg and sperm nuclei into a zygote. The second part of this process is the fusion of the polar nuclei with a second sperm cell nucleus, thus forming a primary endosperm. Right after fertilization, the zygote is mostly.
