NEETBotanyMorphology of Flowering Plants
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Flowers of Cassia and Gulmohur exhibit imbricate aestivation. Reason (R): In these flowers, one margin of the appendage overlaps that of the next one and so on in a particular direction. In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- ABoth (A) and (R) are correct and (R) is the correct explanation of (A)
- B(A) is correct but (R) is not correct
- CBoth (A) and (R) are correct but (R) is not the correct explanation of (A)
- D(A) is not correct but (R) is correct
Correct answer
B. (A) is correct but (R) is not correct
Step-by-step solution
Assertion (A) is correct. Cassia and Gulmohur are classic examples of flowers exhibiting imbricate aestivation. Reason (R) is incorrect. In imbricate aestivation, the margins of sepals or petals overlap one another but not in any particular direction. The description given in the Reason (overlapping in a particular direction) corresponds to twisted aestivation, not imbricate. Therefore, (A) is correct but (R) is not correct. Answer: (A) is correct but (R) is not correct
