| (i) Cleistogamy can favour only autogamy. Justify. |
| (ii) Why emasculation is not required in unisexual flowers? |
Answer:
(i) In cleistogamy, flowers never open at all. Hence, foreign pollen will not land on the stigma of such flowers. So, cleistogamy can favour only self-pollination or autogamy. (ii) In unisexual flowers, emasculation is not needed because the female flowers are bagged before the flowers open. When the stigma becomes receptive, pollination is carried out using the desired pollen and the flowers are rebagged.
