Biology Question on sexual reproduction in flowering plants
Autogamy can occur in a chasmogamous flower if
A
pollen matures before maturity of ovule
B
ovules mature before maturity of pollen
C
both pollen and ovules mature simultaneously
D
both anther and stigma are of equal lengths
Answer
both anther and stigma are of equal lengths
Explanation
Solution
Autogamy is pollination within a flower. Chasmogamous flowers are those in which anthers and stigma are exposed. For autogamy, in such a flower to take place, pollen and ovule should mature simultaneously and anther and stigma should lie close to each other.
