Question

Explain three different modes of pollination that can occur in a chasmogamous flower.

Answer 1

Three different modes of pollination that can occur in a chasmogamous flower are as follows:

1. Autogamy or Self-pollination: This process involves either pollen grains moving from the anther to the stigma of the same flower or pollination occurring within the same flower.
2. Geitonogamy: The movement of pollen grains from the anther to the stigma of a different flower on the same plant is known as geitonogamy.
3. Xenogamy or Cross pollination: Transfer of pollen grains from the anther to the stigma of flowers of a different plant is known as xenogamy or cross-pollination.
