Answer:
Explanation:
Cleistogamy is the phenomenon, where flowers never open and in such flowers, only self-pollination occurs within the bud (unopened flower). Bisexual flowers that 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. Example of Cleistogamous flowers is Viola. Viola has two kinds of flowers, Chasmogamous flowers that are formed on the upper branches in early season, which are pollinated by insects and Cleistogamous flowers that are formed above the ground late in the season.
So, the correct answer is A
