Pollination refers to the transfer of pollen grains from the anther of a flower to the stigma of the same or a different flower. Pollination is a significant process as it helps in fertilisation by bringing the male gamete (male pronucleus) closer to the female (egg) and allowing their fusion. It, therefore, helps in the production of seeds and fruits and thereby help in reproduction as the seeds formed helps in generation of new offsprings. Cross-pollination (in which the pollen grains of one flower are transferred to the stigma of a different flower) helps in the introduction of new variations in plants.
