What is the key difference between cross-pollination and self-pollination in flowering plants?

Explanation

Cross-pollination occurs when pollen is transferred from a flower on one plant to a flower on a genetically different plant of the same species, typically increasing genetic diversity within a population, while self-pollination occurs when pollen from a flower fertilizes the same flower or another flower on that same individual plant. Many plant species have evolved specific structural or timing-related adaptations that favor one method over the other, though some plants are capable of both under different circumstances. Greater genetic diversity resulting from cross-pollination can potentially help a plant population better adapt to changing environmental conditions or resist disease over time.
