1. The Problem of Fruit Plant Reproduction, Fruit and Seed Dispersal

2. How do plants reproduce?  Plants use flowers or cones to fertilize the egg  Pollen and eggs

3. How do plants reproduce  Plants depend on animals or force of nature to pollinate them  Flowers: animals, insects  Cones and other: wind, water

4. Problem 1  Flowers are pretty and take a ton of energy to create  Why would a plant invest so much energy and time into a pretty flower, or into crazy reproductive parts?

5. To attract an make fertilization possible

6. Pollination  Pollen moves through “style”  #swag  And fertilizes an egg in the ovary

7. Ovary becomes fruit

8. Problem 2  Why would a plant spend so much energy to create a fruit?

9. To transport seeds

10. Seed movement  Animals might burry seed  Squirrel burry acorn  Animals might poop seed  Apple, Berries, Vegetables  Seed might float away  Coconut

11.  Why is moving seeds important?

12. Other Seed Dispersal Methods  Burrs, Wind, Spores

13. Seed Dispersal Success Depends Upon  Type of animals  Environmental factors  Number of seeds produced  Seed landing in right spot

14. Review  Why do seeds spend so much energy creating flowers and systems of fertilization?  Why do seeds invest so much energy in fruit production?

15. Practice  Why would a plant be more successful as a species if it is spread out over a wide geographical area?  What are some factors that affect the successful germination of seeds?
