Question

(ii) Compare the two types of flowers with reference to:
(1) Characteristic feature
(2) Modes of pollination

Hint:

Crosspollination promotes genetic diversity, while selfpollination ensures reproduction in unfavorable conditions.

Answer 1

Characteristic feature: Chasmogamous flowers: Open flowers, reproductive parts exposed. Cleistogamous flowers: Closed flowers, reproductive parts not exposed. Modes of pollination: Chasmogamous flowers: Crosspollination facilitated by agents like wind, insects, or water. Cleistogamous flowers: Selfpollination occurs as flowers never open.
