Question
Chapter 45.6, Problem 1CSC
Summary Introduction
To determine:
Some other ways, besides bird dispersal, that fruits have adapted to disperse their seeds.
Introduction:
Seed dispersal is the process of transport of seeds from their parent plant to other places. As plants do not show mobility, they rely upon their fruits and various vectors for their seed dispersal.

Imagine that you are a member of a research group conducting research on fruit type and seed dispersal. Your group has submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document.Question: Why is seed dispersal important in the life of plants? What would be the consequences of having seeds that simply fell to the ground underneath the parent tree?

- In wild columbine, flower morphology encourages crosspollination. However, during the middle of the receptive period of the stigma, self-pollination can occur if the flower was not previously pollinated. If cross-pollination occurs after selfpollination, then that pollen reaches the base of the style before the self-pollen.
