How does cleistogamy ensure autogamy ?​

Answer 1

Explanation:

${\mathfrak{\boxed{\huge{\red{Answer:}}}}}$

Cleistogamous flowers do not open at all. In such flowers , the anthers and stigma lie close to each other. When anthers dehisce in the flower buds, pollen grains come in contact with stigma to effect pollination. So cleistogamous flowers are autogamous as there is no chance of cross pollen landing on stigma.

Hope it helps you ✌️
