Please help: What is the function of the rough surface of the pollen grains?
Also, 2. Why is it helpful that different types of plants have differently shaped pollen grains

In some cases the rough surface helps the pollen float in the air. It needs different shapes at least partially because they are transported to the female part of the plant in different ways. It doesn't need to float if the pollen is spread by insects.
