हिन्दीGiven below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): In a pinnately compound leaf, a number of leaflets are present on a common axis called the rachis. Reason (R): The rachis represents the modified petiole of the leaf. In the light of the above statements, choose the correct answer from the options given below:
Correct answer · Option 4
(A) is false but (R) is true.
Explanation
The rachis represents the midrib of the leaf, not the petiole. Hence Assertion is false, but statement about rachis having leaflets is true if framed as midrib (NCERT states: rachis, which represents the midrib of the leaf).
