Pollination is the transfer of pollen from the male anther of a flower to the female stigma. Once there, the pollen germinates and forms a pollen tube that grows down the style to the ovary, where it fertilizes the ovules.
This process is essential for the reproduction of flowering plants and the production of seeds, which contain the embryos of new plants.
Self-Pollination: Pollen moves from the anther to the stigma of the same flower. This is common in plants with few pollinators and can ensure reproduction even in isolation.
Cross-Pollination: Pollen is transferred between different flowers, often carried by wind or insects. This promotes genetic diversity and is widespread in nature.
Pollination is vital for producing food, fiber, and countless other plant products, making it a cornerstone of both natural ecosystems and agriculture.
