Which one of the following statements is correct?
Options
(a) Geitonogamy involves the pollen and stigma of flowers of different plants
(b) Clestogamous flowers are always autogamous
(c) Xenogamy occurs only by wind pollinations
(d) Chasmogamous flowers do not opeon at all
Correct Answer:
Clestogamous flowers are always autogamous
Explanation:
Cleistogamous flowers do not expose their reproductive parts. Anthers and stigma lie close to each other. Pure autogamy occurs since there is no chance of cross-pollination. Cleistogamy is the most efficient floral adaptation for promoting self-pollination. E.g., Viola mirabilis and Oxalis autosella.
