Current Question (ID: 13148)

Question:

Go through the following statements: Flowers are bisexual and homogamous maturing anther and stigma of a flower at the same time. Mechanical devices bringing anthers and stigma close together in a bisexual chasmogamous flower. Cleistogamy (bisexual flowers remain closed) Anther and stigma of an intersexual flower mature in bud condition. The above contrivances favour:

Options:

1. Allogamy
2. Autogamy
3. Xenogamy
4. Cross pollination

Solution:

The above mentioned points explains autogamy. Allogamy: It is the deposition of pollen grains from the anther of one flower to the stigma of another flower, either in same plant or different plant of the same species. Xenogamy: Transfer of pollen grains from anther to the stigma of a different plant. This is the only type of pollination which during pollination brings genetically different types of pollen grains to the stigma. Cross pollination: The transfer of pollen grains from anther of one plant to the stigma of another plant.
