Draw a pollen grain that might be released from a wind-pollinated plant, and a pollen grain that might be released from an animal-pollinated plant.

Explain the differences between pollen grains released from wind pollinated plant and those release from animal pollinated plants.

If pollination is successful, a pollen grain lands on a stigma of the same species. Give a step-by-step description of what happens from when the pollen grain lands on the stigma to when the fruit is formed.

Explain why you might see tiny oak trees sprouting in a park where there is already an oak tree growing.
