9.3.3 Dicotyledonous Seed Structure and Function

Testa protects the plant embryo and the cotyledon food stores

Radicle is the embryonic root

Plumule is the embryonic stem

Cotyledonous is the food store for the seed.

Micropyle is a hole in the testa through which the water can enter  the seed prior to germination

Scar is where the ovule was attached to the carpel wall
