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): The flowers of Canna cannot be divided into two similar halves by any vertical plane passing through the centre. Reason (R): Canna flowers are asymmetric. 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).
- BBoth (A) and (R) are correct but (R) is not the correct explanation of (A).
- C(A) is correct but (R) is not correct.
- D(A) is not correct but (R) is correct.
Correct answer
A. Both (A) and (R) are correct and (R) is the correct explanation of (A).
Step-by-step solution
A flower is asymmetric (irregular) if it cannot be divided into two similar halves by any vertical plane passing through the centre, as seen in Canna. Thus, the Assertion is a correct statement. The Reason correctly states that Canna flowers are asymmetric, which is the exact explanation for why they cannot be divided into two similar halves. Therefore, both (A) and (R) are correct and (R) is the correct explanation of (A). Answer: Both (A) and (R) are correct and (R) is the correct explanation of (A).
