(i) gram seed
Structure of gram seed-
It is a dicotyledonous seed that develops inside a tiny legume or pod. The outer seed coat, or testa, and the inner seed coat, or tegmen, cover the seed. The seed coverings envelop the embryo. Two enormous cotyledons, joined by short stalks, press on the embryo's short, straight embryo axis. Future roots are formed by a radicle on the micropylar end of the embryo axis. The plumule, which produces branches, is the opposite end of the embryo axis. The cotyledons are where the nourishment is kept. The place to which the seed's stalk is attached is called the hilum.
