Detailed explanation-1: -Pollination is the act of transferring pollen grains from the anther, i.e., the male part of a flower, onto the pistil, i.e., the female part of a flower. The transfer between male and female parts can be within the same flower or to a different flower of the same species.
Detailed explanation-2: -Pollination is the transfer of pollen grains from an anther to a stigma. Pollen can be transferred by an animal or by the wind. Fertilisation takes place inside the ovary when the nucleus of pollen grain fuses with the nucleus of an ovule to produce a zygote.
Detailed explanation-3: -Pollination is the process that brings these male and female gametes together. Pollen can’t get from the anthers to the ovules on its own, so pollination relies on other things to move the pollen. The wind or animals, especially insects and birds, pick up pollen from the male anthers and carry it to the female stigma.
Detailed explanation-4: -Pollination is an essential part of plant reproduction. Pollen from a flower’s anthers (the male part of the plant) rubs or drops onto a pollinator. The pollinator then take this pollen to another flower, where the pollen sticks to the stigma (the female part). The fertilized flower later yields fruit and seeds.
