Answer:
pollination is the act of transferring polle grains from the male anther of a flower to the female stigma. the goal of everi living organisms, include plant,is to create offspring of the next generation. one of the ways that plant can produce offspring is by making seeds.
self pollination occurs when the pollen from the anther is deposite on the stigma of the same flower or another flower on the same plant.
cross pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.
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 help in fertilisation bi bringing the male gamete (male pronucleus) closer to the female (egg) and allowing their fusion.
