Introduction:-
Cross Pollination:– Cross-pollination is a plant reproductive process where pollen is transferred from the male reproductive organ (stamen) of one flower to the female reproductive organ (stigma) of another flower, typically from a different individual within the same species. This process often relies on external agents such as wind, insects, birds, or other animals to facilitate the transfer of pollen between flowers. Cross-pollination promotes genetic diversity among offspring, which can be advantageous for a species’ long-term survival and adaptation to changing environments. Many flowering plants have evolved various mechanisms to encourage cross-pollination, ensuring a mix of genetic traits and reducing the risk of inbreeding.
