Question

Differentiate between self-pollination and cross-pollination.

Hint:

Cross-pollination promotes genetic diversity, which is beneficial for the adaptability of species.

Answer 1

\[ \begin{array}{|l|l|} \hline \textbf{Self-pollination} & \textbf{Cross-pollination} \\ \hline \text{Pollen from the same flower or plant fertilizes the stigma.} & \text{Pollen from one plant fertilizes the stigma of another plant of the same species.} \\ \hline \text{No involvement of other plants.} & \text{Involves different plants.} \\ \hline \text{No external agents; pollen remains within the same plant.} & \text{Often involves external agents like wind, water, or animals.} \\ \hline \text{Results in less genetic variation.} & \text{Promotes genetic diversity, leading to more adaptability.} \\ \hline \text{Examples: Pea plants, wheat.} & \text{Examples: Apple, cherry, and many flowers.} \\ \hline \end{array} \]
