1. Sexual Reproduction
SWBAT identify and describe the following flower parts and the function of each; sepals, petals, stamens, and pistils; distinguish between pollination and fertilization in flowers; explain various ways that plants may be pollinated; list several ways in which plants disperse seeds.

2. Quick Review
What are traits?
What are genes?
What are gametes?

3. Sexual Reproduction
How does sexual reproduction create genetic variation?
Only one chromosome is taken from each parent, so the offspring can look like mom, dad, or a combination of the two
Haploid
Cells that have only ½ the chromosomes of a regular cell (this is what is found in gametes)

4. Flowers
Sepals
Leaf-like structures positioned at the outermost base of the flower
Protect the flower while it is developing
Petals
Largest and most colorful part of a flower. They provide the color and design of the flower
Help attract insects and animals that aid in pollination

5. Flowers
Stamen
Male reproductive part of a flower. It’s made up of two parts; long thin filaments and the anther which is filled with pollen grains
Produces pollen grains which are the male gametes

6. Flowers
Pistil
Female reproductive part of a flower. It’s made up of three parts; ovary, style, and stigma, which is the sticky part pollen catches on
Collects pollen for reproduction and draws into the ovary to produce seeds

7. Pollination Pollination Ovules Seed
Process of transferring pollen form an anther to a stigma
Ovules
Contains the eggs of the plant
Seed
Protects the embryo and stored food

8. Pollination How is pollination different from fertilization?
Pollination is the moving of pollen. Fertilization doesn’t happen until the pollen tube as connected with the ovary and produced a zygote

9. Facets of Botany: The Pollen Movers
What is a pollinator?
Anything that transfers pollen from the stamen to the stigma
List some examples of pollinators.
Insects – bees
Butterflies and moths
Birds and bats
Wind

10. Facets of Botany: The Pollen Movers
How do pollinators spread the pollen?
Unintentionally. When they drink nectar they pick up pollen on their bodies which is then transferred to another plant of the same species, when they land to drink from it.
Self-Pollination
Pollen from the same plant fertilizes itself
Cross-Pollination
Pollen from a different plant fertilizes it

11. Facets of Botany: Scattering Seeds
What are some of the different methods plants use to scatter seeds?
Cones
Flung from a coil
Fruit is eaten by animals and the seed passes through their system
Hook method
Wind
Water
Humans
