Question

Cleistogamous flowers are

• A. Male female which never open
• B. Female flowers which never open
• C. Bisexual flowers which never open
• D. Open bisexual flowers which perform self pollination in bud condition

Answer 1

The correct option is C Bisexual flowers which never open

Cleistogamy is the phenomenon, where flowers never open and in such flowers, only self-pollination occurs within the bud (unopened flower). Bisexual flowers which do not open at all are called cleistogamous. In such flowers, anthers and stigma lie close to each other. When the anthers dehisce in the flower buds, pollen grains come in contact with the stigma and pollination occurs.

So, the correct answer is C.
