Parts and their functions

• Seed coat (bean) (बीजावरण) — Formed from the integuments; hard, protects the embryo.
• Cotyledon (bean) (बीजपत्र) — Thick, swollen — stores food. Bean/pea/groundnut are NON-ALBUMINOUS: no residual endosperm, it was fully used by the embryo.
• Plumule (प्रांकुर) — Shoot tip of the embryo.
• Radicle (मूलांकुर) — Root tip of the embryo.
• Hilum (नाभिका) — Scar on the seed coat where the seed was attached to the fruit (funicle).
• Micropyle (बीजांडद्वार) — Remains as a small pore in the seed coat; lets oxygen and water in during germination.
