Flexi Says: Pollination is transferring of pollen grains from the male anther of a flower to the female stigma of another flower. Pollination is the first step in fertilization and leads to the production of seeds. Pollinating agents are animals such as insects, birds, and bats; water; wind; and even plants themselves, when self-pollination occurs within a closed flower. Pollination typically occurs within a species, but cross-pollination between two species can sometimes occur and produce hybrid offspring.
