Pollination is a process in which pollen is transferred to the female reproductive organs of seed plants, thereby enabling fertilization and reproduction through growth of the pollen tube and eventual release of sperm.ollination is a necessary step in the reproduction of flowering plants, resulting in the production of offspring that are genetically diverse. The study of pollination brings together many disciplines, such as botany, horticulture, entomology, and ecology.
