Cross-pollination occurs when pollen from a flower lands on the stigma of a different plant of the same kind. This helps in genetic diversity and the creation of healthy plants.

Understanding Cross-Pollination
Cross-pollination is a vital process in the reproductive cycle of flowering plants. It occurs when pollen from the anther of one flower lands on the stigma of a flower of a different plant of the same species. This process enhances genetic diversity and is crucial for the evolution and adaptability of plant populations.
Key Aspects of Cross-Pollination:
- Definition: Cross-pollination specifically involves the transfer of pollen between different individuals of the same species, as opposed to self-pollination, where pollen from a flower fertilizes its own ovules.
- Mechanisms: Cross-pollination can occur through various agents, including:
- Wind
- Insects (like bees and butterflies)
- Birds
- Water
- Benefits: The advantages of cross-pollination include:
- Increased genetic diversity, leading to more resilient plant populations.
- Higher rates of seed production and better quality seeds.
- Enhanced adaptability to environmental changes.
- Contrast with Self-Pollination: While self-pollination ensures that a plant can reproduce even in isolation, it does not promote genetic variation as effectively as cross-pollination does.
Conclusion:
In summary, cross-pollination is a fundamental process in botany that promotes genetic diversity and strengthens the resilience of plant species. Understanding this process is essential for appreciating how ecosystems function and evolve over time.

When the Pollen grains land on the stigma of a flower of a different plant of the same species it is known as cross pollination.
when pollen grains land on the stigma of a flower of the same plant or another flower on the same plant it is known as self pollination.
