Answer:
This transfer of pollen from one flower to another is called cross-pollination. If the pollen is transferred to the stigma of the same flower it is called self-pollination. Pollen grains are also adapted for insect pollination. ... The stigmas are long and feathery, which gives a large surface area for catching pollen.

Answer:
Pollen grains are also adapted for insect pollination. Some pollen grains are hairy or spiky, and others are sticky, so they attach to the insect. Plants like wild grasses and cultivated cereals are wind pollinated.
