The transfer of a pollen grain from the anther to the stigma is called pollination. This process is crucial for the reproduction of flowering plants, as it allows for the sperm cells contained within the pollen to reach the ovules in the ovary, ultimately leading to fertilization. Pollination can occur through various means, including wind, water, and animal pollinators, such as bees or butterflies, which facilitate the movement of pollen between flowers.

Fertilization, while an important part of the reproductive cycle, occurs after pollination when the pollen grain's sperm fertilizes the ovule. Germination refers to the process by which a seed develops into a new plant, and seed dispersal involves the spreading of seeds from the parent plant to new locations. These processes, while related to the life cycle of plants, occur at different stages and are distinct from the initial transfer of pollen.
