Final answer:
Pollination is the process of transferring pollen from one flower to another, either on the same plant (self-pollination) or on a different plant (cross-pollination).
Step-by-step explanation:
Pollination is the process of transferring pollen from the anther to the stigma of a flower. It can occur in two forms: self-pollination and cross-pollination. Self-pollination happens when the pollen from the anther is deposited on the stigma of the same flower or another flower on the same plant.
Cross-pollination occurs when pollen is transferred from the anther of one flower to the stigma of another flower on a different plant. This type of pollination requires the help of pollinators such as bees, butterflies, or wind.
