Assertion (A) : In a monocotyledonous stem, the vascular bundles are surrounded by a sclerenchymatous bundle sheath. Reason (R) : The ground tissue in a monocotyledonous stem is highly differentiated into cortex, endodermis, pericycle, and pith.

Options

  1. ABoth Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A)
  2. BBoth Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A)
  3. CAssertion (A) is true but Reason (R) is false
  4. DAssertion (A) is false but Reason (R) is true

Correct answer

C. Assertion (A) is true but Reason (R) is false

Step-by-step solution

In a monocotyledonous stem, the vascular bundles are scattered, conjoint, collateral, and closed. Each vascular bundle is surrounded by a sclerenchymatous bundle sheath. Thus, Assertion (A) is true. The ground tissue in a monocotyledonous stem is a continuous mass of parenchymatous cells and is not differentiated into cortex, endodermis, pericycle, and pith. Thus, Reason (R) is false. Answer: Assertion (A) is true but Reason (R) is false
