  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?

  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?
