Detailed explanation-1: -Flowering plants or angiosperms reproduce sexually by the process known as pollination. In this process, the pollen from the male anther is transferred to the female stigma. These pollens travel through the pollen tube and produce gametes which fuse with the egg in the embryo sac. This gives rise to fruit.

Detailed explanation-2: -Pollination is the process of transferring the plant’s male reproductive cells (pollen) to the plant’s female reproductive structures (stigma and style) so that sperm and egg can meet resulting in a new plant.

Detailed explanation-3: -The transfer of pollen grains from the male to the female reproductive structure is known as pollination. Pollination is the process of transfer of pollen grains (male gametes) from the anther (male reproductive structure) to the stigma (female reproductive structure).

Detailed explanation-4: -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-5: -Geitonogamy is the type of self-pollination where the transfer of pollen grains from the anther to the stigma takes place between different flowers in the same plant.
