1.Pistil:female reproductive structure
Stigma: sticky tip; traps pollen
Style: slender tube; transports pollen from stigma to ovary
Ovary: contains ovules; ovary develops into fruit
Ovule: contains egg cell which develops into a seed when fertilized

Stamen
Stamen: male reproductive structure
Filament: thin stalk; supports anther
Anther: knob-like structure; produces pollen
Pollen: contains microscopic cells that become sperm cells

Sepals: encloses & protects flower before it blooms
Petals: usually colorful & scented; attracts pollinators

5. Cross Pollination How does pollination happen?
Slide # 15
Cross Pollination
How does pollination happen?
Pollen from an anther is caught by the stigma, travels through style to the ovules in the ovary.
What is the result of pollination?
A Fruit: An ovary containing seeds.

6. Monocot vs. Dicot

7. Monocot vs. dicot Angiosperms are divided into monocots and dicots
As the zygote grows into the embryo, the first leaves of the young sporophyte develop and are called as cotyledons (seed leaves)
Monocots have one cotyledon (corn, lily, etc).
Dicots have two cotyledons (bean, oak, etc).

8. Monocot vs. dicot
Number of cotyledons: one vs. two

9. Monocot vs. dicot Flower parts: Monocot: in groups of three
Dicot: in groups of four or five

10. Monocot vs. dicot Leaf venation pattern: Monocot is parallel
Dicot is net pattern

11. Monocot vs. dicot root
Monocot: Fibrous root
Dicot: Tap root

12. Monocot vs. dicot Stem type: Monocot: Herbaceous
Dicot: herbaceous or woody
