Sexual Reproduction In Flowering Plants

Question

In which one of the following pollination is autogamous?

Xenogamy

Chasmogamy

Cleistogamy

Geitonogamy

Solution

Cleistogamy

Bisexual flowers which remain always closed are called the cleistogamous and such condition of flowers is called cleistogamy. In such flowers, the anthers and stigma lie close to each other. When anthers dehisce in the flowers buds, pollen grains come in contact with stigma to effect pollination. Thus, cleistogamous flowers are invariably autogamous.
