Question

Which of the following is true about autogamy?
I. Pollen grains are deposited on the stigma of the same flower.
II. It requires synchrony in pollen release and stigma receptivity.
III. Autogamy cannot occur without pollinating agents.
IV. Anthers and stigma needs to be close.

• A. I, II and III are correct
• B. II, III and IV are correct
• C. I, II and IV are correct
• D. Only I and II are correct

Answer 1

The correct option is C I, II and IV are correct

In autogamy (self-pollination), pollen grains are deposited on the stigma of the same flower. Hence the flower should be bisexual. Since the pollination occurs within the same flower there is no need for pollinating agents.
Self pollination requires synchrony between the pollen release and stigma receptivity.
Also the anthers and the stigma needs to be close for self-pollination to occur.
