Pollination is the transfer of pollen grains from the anther to the stigma of a flower.

The anther is the part of the stamen that produces pollen grains.

Carpel (or pistil) is the female part consisting of stigma style and ovary.

The stigma is sticky to capture pollen grains during pollination.

Wind water insects birds and bats can all act as pollinators.

Self-pollination occurs when pollen moves to the stigma of the same flower or another flower on the same plant.

Cross-pollination involves transfer of pollen between flowers on different plants.

Pea tomato and rice are examples of self-pollinating plants.

Apple papaya and poplar are cross-pollinated plants.

Cross-pollination often produces stronger and more diverse offspring.
