Open in App
Solution
The correct option is B Oryza sativa
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. In Oryza sativa (rice), anther and stigma mature before the opening of the flower and thus, self-pollination is promoted.Hence, cleistogamy is effective in Oryza sativa.So, the correct answer is A.
