Seed Development and Germination

Ovules Ovule has an embryo, endosperm, and coverings – Gets nutrients from plant

Seeds When coverings thicken and seal, food is stored and seed is formed. – Seed coat, endosperm, embryo

Seeds Cotyledons – Part of the embryo that absorbs nutrients from endosperm so growth can occur

Fruit Ovary ripens as ovule develops Eventually, fruit surrounds seeds

Fruit Types Dry Fruits – Legume – Achene – Nut – Samara – Caryopsis

Fruit Types Fleshy Fruits – Drupe – Hesperidium – Pepo – Pome – Aggregate – Multiple

Germination Seeds take in water, swell, and rupture – Seed coat broken by scratching, freezing, fire, etc. More oxygen, more cell division Primary root emerges 1 st, then shoot
