Pollination is the process in which the pollen grains from stamen is transferred to the stigma of flower. Insects like bees helps in pollination and pollination from insect called entomophily.
So bees are responsible for pollination during the life cycle of flowering plant. Pollination can be self-pollination and cross-pollination. In self-pollination pollen from a stamen falls on the stigma of the same flower and in cross-pollination, the pollen from the anther of one flower falls on stigma of a different flower.
