1.) Discuss why is the ovulate cone of a pine designed to be so much more durable than the staminate cone? (think about where fertilization and seed development occur, and how long it takes.)

2.) In pine, both the staminate and ovulate cones occur on the same tree, but not on the same branch. The ovulate cones are usually at the top of the trees, so that pollen from their own tree will NOT fall onto and fertilize the eggs. Why would this be an andvantage?

3.) What is the advantage of having seeds rather than spores?
