Seed Dispersal•Disperse means to spread out. •Seeds must be dispersed!!!!•Seeds grow best if they are AWAY from their parent plant.

•Parent plants block sunlight and soak up water and nutrients that the seedling needs.

•Seeds disperse from the parents by wind, water, or animals.

Horrible fashion, great seed dispersal!!!!

When these seeds fall off, theycan begin to grow.

These seeds are dispersed by the wind. How does their shape help in dispersal?

This coconut will eventually grow intoa new palm tree. Does this explain why palm trees are only found in coastal areas?

How do animals like these animals help with seeddispersal?

How about these monkeys? How will they help disperse the seeds found in the fruit?
