Annotate the structure of a maize and a bean germinating seed

Maize Seed (Monocot):

1. Pericarp and Seed Coat: Fused outer layer, protective.
2. Endosperm: Large starchy tissue, primary food source.
3. Scutellum (Cotyledon): Thin, shield-shaped structure that absorbs food from the endosperm and transfers it to the embryo.
4. Coleoptile: Protective sheath covering the plumule (embryonic shoot).
5. Plumule: Contains the embryonic leaves and stem.
6. Radicle: Embryonic root, covered by the coleorhiza (protective sheath).

Bean Seed (Dicot):

1. Seed Coat (Testa): Outer protective layer, often two-layered.
2. Hilum: Scar where the seed was attached to the ovary wall.
3. Micropyle: Small pore near the hilum, allows water entry.
4. Embryo: Consists of:
   • Two large Cotyledons: Fleshy structures storing food (starch, proteins, oils).
   • Embryonic Axis:
     • Plumule: Develops into the shoot (stem and leaves).
     • Radicle: Develops into the root.
     • Hypocotyl: Connects the cotyledons to the radicle.
     • Epicotyl: Part of the embryonic axis above the cotyledons.
