Explain the difference between crosspollination and self pollination in plants?

Answer 1

Cross pollination is when pollination occurs between two different varieties of plant, which do not ordinarily pollinate each other, thus producing a new, hybrid variety of plant. Self pollination is when a single plant pollinates itself, thus there is no mixing of genetic material, the offspring will have only one parent instead of two.

Answer 2

Self-pollination is the process by which pollen from the stamen of a flower is transferred to the pistil of a flower of the same plant whereas cross-pollination is the transfer of pollen from the stamen of a flower to the pistil of a flower of a different plant.

Answer 3

Cross-pollination occurs when pollen is transferred between flowers of different plants, promoting genetic diversity. In contrast, self-pollination involves the transfer of pollen within the same flower or between flowers of the same plant, limiting genetic diversity. Cross-pollination usually requires the assistance of external agents like insects or wind, while self-pollination can occur through self-fertilization mechanisms in the plant itself.
