1. WARM UP “A weed is but an unloved flower.” –Ella Wheeler Wilcox
What does this mean to you?
How does this apply to plants and reproduction?

2. Seed Development and Germination

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

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

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

6. Fruit
Ovary ripens as ovule develops
Eventually, fruit surrounds seeds

7. Fruit Types Dry Fruits Legume Achene Nut Samara Caryopsis Has a seam
Peanut
Achene
Many fruits attached to large “wall”
Sunflower and strawberries
Nut
Very hard covering
Samara
Wing-like structure
Caryopsis
Fruits/seeds fused to wall

8. Fruit Types Fleshy Fruits Drupe Hesperidium Pepo Pome Aggregate

Lemons, limes
Pepo
Thin rind
Cucumber, cantaloupe
Pome
Flower petals form skin

Aggregate
Many ovaries in a single flower make multiple fruit sections
Blackberries
Multiple
Many separate flowers make separate fruit sections
Pineapple

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

10. WRAP UP Name 3 “vegetables” that are actually fruits.
Name 3 vegetables that are truly vegetables.
