Assertion: Cleistogamous flowers require pollinating agents.
Reasoning:: Chasmogamous flowers do not expose their sex organs.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) →Both Assertion (A) and Reason (R) are false.
Explanation:
Assertion: "Cleistogamous flowers require pollinating agents." – False
- Cleistogamous flowers remain closed and undergo self-pollination without the need for external pollinators.
- Since anthers and stigma are enclosed within the same flower, pollen transfer occurs automatically, ensuring assured seed-set even in the absence of pollinators.
Reason: "Chasmogamous flowers do not expose their sex organs." – False
- Chasmogamous flowers are open flowers, where the stigma and anthers are exposed to facilitate cross-pollination by wind, insects, or other agents.
- Since their reproductive organs are exposed, they do not rely solely on self-pollination like cleistogamous flowers.
