उत्तर
Pollination: It is the reproductive organ of the plant. A flower contains the male parts (stamens) and the female parts (carpels). The pollen grains from the male part are transferred (by air or insects) to the female part of the flower. This transfer of pollen from anther to stigma is called pollination.
