Introduction:-

Self Pollination:- Self-pollination, a common reproductive mechanism in plants, occurs when pollen from a flower’s male reproductive organ (stamen) lands on and fertilizes the female reproductive organ (stigma) of the same flower or another flower on the same plant. This process can be facilitated by various means, such as gravity, wind, or physical contact.

Self-pollination ensures a plant’s reproduction even in the absence of external pollinators like insects or wind. While it guarantees successful fertilization, it often results in limited genetic diversity within offspring, potentially reducing adaptability to changing environments. However, some plants have developed mechanisms to promote outcrossing (cross-pollination between different plants) to introduce genetic variation, which can be beneficial for long-term survival and evolution.
