Question

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 ovule mature simultaneously
• D. None of these

Answer 1

The correct option is C both pollen and ovule mature simultaneously

Chasmogamous flowers are the flowers with exposed anthers and stigma. For autogamy (transfer of pollen from anther to stigma of the same flower) to occur in chasmogamous flowers both pollen and ovule should mature simultaneously. There should be synchrony between pollen release and stigma receptivity.
