Answer:
The Internal Structure of a Seed — The seed is covered by a hard, tough covering called testa. Inner to the tests is the embryo. The Embryo consists of two cotyledons and an embryo axis. The Embryo axis has plumule and radicle. The plumule is present in between the two cotyledons and its top bears two folded tiny leaves. It forms future shoots and leaves of the growing seed. Radicle is rod-shaped and is out of the two cotyledons. It forms the root of the growing seed. When the seed grows the two cotyledons come out of the soil and form cotyledonary leaves and turn green in color. Cotyledons give food to the growing seedling as it has food. The germination in this seed is epigeal as cotyledons come outside the soil in the growing seed.
