Definition - What does Pollen mean?

Pollen is a powdery, microscopic grainy substance found in plants or flowers that contain the male gametes. Pollen is transported by the wind, insects, or other animals from one flower to another, where it fertilizes female ovules, resulting in new seeds. In aquatic plants, pollen grains are protected by a double wall.

Pollination agents can be bats, birds, butterflies, moths, bees, and other such insects. In seed plants, pollen can be transferred either through cross-pollination or through self-pollination. It is important to understand the different aspects of pollen transfer, since proper pollination can largely enhance crop quality and growth.

In some cases, pollen can be transferred by the wind. Oaks, pines, maples, and grasses largely benefit from wind pollination, while violets, sunflowers, roses, and other flowers with wide, brightly colored petals are pollinated by insects. Some birds, such as the hummingbird, are attracted to flowers by their nectar guides, again resulting in the transfer of pollen from one plant to another.
