Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Secondary xylem and secondary phloem are considered redifferentiated tissues. Reason (R): They are formed by the division of primary meristems and subsequently lose their capacity to divide to perform specific functions. In the light of the above statements, choose the most appropriate answer from

Options

  1. ABoth Assertion and Reason are correct and Reason is the correct explanation for Assertion.
  2. BBoth Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
  3. CAssertion is correct but Reason is incorrect.
  4. DAssertion is incorrect but Reason is correct.

Correct answer

C. Assertion is correct but Reason is incorrect.

Step-by-step solution

Assertion (A) is correct: Secondary xylem and secondary phloem are formed by the division of vascular cambium (a dedifferentiated tissue). The newly formed cells lose their capacity to divide and mature to perform specific functions. This phenomenon is termed redifferentiation. Reason (R) is incorrect: Secondary xylem and secondary phloem are formed by the division of secondary meristems (vascular cambium), not primary meristems. Primary meristems form primary permanent tissues through differentiation. Answer: Asse
