Detailed explanation-1: -Pollination : The mechanism of transferring pollen grains from the anther of one flower to the stigma of another flower of the same or different plant is called pollination. The pollen grains can be transferred to the stigma of the flower through wind, water and insects called pollinating agents.

Detailed explanation-2: -cross-pollination, also called heterogamy, type of pollination in which sperm-laden pollen grains are transferred from the cones or flowers of one plant to egg-bearing cones or flowers of another.

Detailed explanation-3: -Pollination by insects is called entomophily and pollination by birds is called ornithophily. Pollination by vertebrates is known as zoophily. Abiotic agents – Wind and water. Wind pollination is known as anemophily and pollination by water is called hydrophily.

Detailed explanation-4: -A pollinator is an animal that moves pollen from the male anther of a flower to the female stigma of a flower. This helps to bring about fertilization of the ovules in the flower by the male gametes from the pollen grains.

Detailed explanation-5: -/ˈpɑː.lə.neɪt/ to take pollen from one plant or part of a plant to another so that new plant seeds can be produced: Bees pollinate the plants by carrying the pollen from one flower to another. Plant reproduction.
