Pollination

Pollination, in plants, the transfer of pollen from the male stamen of aflower to the female pistil of the same or another flower for fertilization. Wind-pollinated plants, such as grasses, produce inconspicuous flowers with large, feathery stamens and stigmas and usually large quantities of pollen. Insect-or bird-pollinated flowers have large, conspicuous, and colorful flowers, produce nectar, and have small stigmas.
