Question

Given below are two statements:
Statement I: Cleistogamous flowers are invariably autogamous
Statement II: Cleistogamy is disadvantageous as there is no chance for cross pollination
In the light of the above statements, choose the correct answer from the options given below:

• A. Both Statement I and Statement II are correct
• B. Both Statement I and Statement II are incorrect
• C. Statement I is correct but Statement II is incorrect
• D. Statement I is incorrect but Statement II is correct

Answer 1

The Correct Option is A

In this exercise, we analyze statements about cleistogamous flowers.

Statement I: Cleistogamous flowers are invariably autogamous.

Explanation: Cleistogamous flowers are those that do not open and thus self-pollinate without external influence. This means these flowers are always autogamous (self-pollinating), as they do not allow any other form of pollination.

Conclusion: Statement I is correct.

Statement II: Cleistogamy is disadvantageous as there is no chance for cross pollination.

Explanation: While cleistogamy ensures seed production due to consistent self-pollination, it restricts genetic variation because there is no opportunity for cross-pollination. Genetic variation is crucial for the adaptability and survival of species in changing environments.

Conclusion: Statement II is also correct, as the lack of cross-pollination can be considered a disadvantage.

Based on the explanations provided for both statements, the correct answer is: Both Statement I and Statement II are correct.
