Structure of Dicotyledonous Seed:

- There are two cotyledons.
- Cotyledons are the embryonal leaves as they store food.
- The outer layer of the seed coat is called testa while the inner layer is called tegmen.
- The hilum is the scar on the seed coat through which the developing seeds were attached to the fruit.
- Within the seed coat, embryo is present.
- Embryo consists of an embryonal axis and cotyledons.
- The radicle and plumule are present on the opposite end of the embryonal axis.
- Food storing tissue called the endosperm is also present. It is formed after triple fusion.
