Question

Which pollination is autogamous?

• A. Geitonogamy
  
• B. Chasmogamy
  
• C. Xenogamy
  
• D. Cleistogamy
  

Answer 1

The correct option is D Cleistogamy


Introduction to autogamy
Autogamy involves the transfer of pollen grains from the anther to the stigma of the same flower.
Chasmogamy
Chasmogamous flowers remain open with their anthers and stigmas exposed to the environment. They have high chances of being cross-pollinated by pollen from other flowers and rarely undergo autogamy.
Geitonogamy
In geitonogamy, the pollen is transferred from the anther of a flower to the stigma of a neighbouring flower of the same plant.
Cleistogamy
Cleistogamous plants bear closed flowers in which the anther and stigma are not exposed to the external environment. These flowers reproduce by autogamy and do not require pollinators.
Xenogamy
Xenogamy occurs when pollen grains are transferred from the anther of one flower to the stigma of another flower on a different plant.
Final answer
(C) Cleistogamy
