Options:
Answer:
Solution:
Cleistogamous flowers do not open at all. In such flowers, the anthers and stigma lie close to each other. When anthers dehisce in the flower buds, pollen grains come in contact with the stigma to effect pollination. Thus, cleistogamous flowers are invariably autogamous as there is no chance of cross-pollen landing on the stigma.
Xenogamy: Transfer of pollen grains from anther to the stigma of a different plant i.e. cross-pollination. This is the only type of pollination which during pollination brings genetically different types of pollen grains to the stigma.
Plants use two abiotic i.e. wind (anemophily) and water(hydrophily) and one biotic (animals) agents to achieve pollination. Pollination by insects is called entomophily.
