Here is the detailed answer:

Pollination in Plants
Pollination is the process by which pollen grains are transferred from the male reproductive organ (anther) to the female reproductive organ (stigma) of a flower. In self-pollination, the transfer of pollen grains occurs between two flowers of the same plant.

Mechanism of Self-Pollination
1. Structure of Flowers: Flowers in self-pollinating plants are often structured in a way that facilitates the transfer of pollen within the same flower or between flowers of the same plant.
2. Pollen Transfer: The pollen grains are transferred from the anther to the stigma of the same flower or a different flower on the same plant. This can happen through wind, water, insects, or other pollinating agents.
3. Ensuring Genetic Variation: While self-pollination leads to genetic uniformity, some plants have mechanisms to prevent self-pollination and promote outcrossing for genetic diversity.

Advantages and Disadvantages of Self-Pollination
1. Advantages: Self-pollination ensures reproductive success in isolated or unfavorable environments, leading to higher seed production.
2. Disadvantages: It limits genetic diversity and can make plants more susceptible to diseases and environmental changes.

Conclusion
Self-pollination is a common reproductive strategy in plants that ensures reproductive success but comes with limitations in terms of genetic diversity. Understanding the mechanisms of self-pollination helps in the conservation and cultivation of plant species.
