Bees contribute to pollination by transferring pollen from the male parts of a flower to the female parts, which allows plants to produce fruits and seeds. Bees collect nectar and pollen from flowers as a food source, and in the process of foraging, pollen grains get stuck to their bodies. As bees move from flower to flower to collect nectar, they inadvertently transfer pollen, facilitating the fertilization process that is crucial for plant reproduction. This pollination process is essential for the reproduction of many plant species and plays a vital role in maintaining biodiversity and ecological balance.
