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

Distinguishing features: Chasmogamous flowers: Characterized by open blooms with readily accessible reproductive organs. Cleistogamous flowers: Feature closed blossoms, concealing their reproductive structures. Pollination mechanisms: Chasmogamous flowers: Undergo cross-pollination, typically mediated by external vectors such as wind, insects, or water. Cleistogamous flowers: Exhibit self-pollination due to their perpetual closed state, preventing external pollen transfer.
