Two Kinds of Pollen
There are two kinds of pollen. One type is produced by flowers that are pollinated by wind. This pollen is light and fluffy, so that it will move far from the original plant. It is also very poor in nutritional value. Plants that rely on wind are called anemophilous, and wind pollination is called anemophily. The word literally means wind-loving.
Some anemophilous plants are grasses, grains (such as wheat and corn), pines, pecans, oaks, and ragweed.

See the pollen grains that have settled on this corn leaf. In a cornfield there is a lot of wind blown pollen, and it settles on any flat surface. Notice that this pollen is not sticky. You can blow it off the leaf with a little puff of breath.

The second kind of pollen is produced by entomophilous plants. This literally means insect-loving, and refers to plants that are pollinated mostly by insects.
