Expert Answer
Structure of a dicot seed:
- A dicotyledonous seed is covered by a seed coat.
- A seed coat is made of two layers—an outer testa and an inner tegmen.
- There is a scar on the seed coat called hilum. Through the hilum, the developing seeds are attached to the fruit.
- A micropyle is the small pore present just above the hilum.
- An embryo is enclosed by the seed coat.
- The embryo has an embryonal axis and two cotyledons.
- The cotyledons are fleshy, and they serve as the food reserves for the developing embryo.
- At the two ends of the embryonal axis are the radicle and the plumule.
