Question

Cleistogamy does not require anthesis because

• A. It assures heterozygosity
  
• B. It favours insect pollination
  
• C. It allows xenogamy
  
• D. No pollination agent is required
  

Answer 1

The correct option is D No pollination agent is required


Anthesis
Anthesis is the opening of floral buds of the plants in the flowering season.
Cleistogamy
Cleistogamous plants bear closed bisexual flowers and reproduce by autogamy in which pollen grains are transferred from the anther to the stigma of the same flower in a plant.
These plants do not require pollinators for pollination to take place. Usually they have the stigma and anther lying at close proximity which favours autogamy.
As cleistogamous flowers undergo autogamy, they ensure homozygosity.
Final answer
(a) No pollination agent is required
