(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.
