Question

Assertion (A) Vascular bundles in monocots are considered closed.
Reason (R) A bundle sheath surrounds each vascular bundle in monocots.

• A. If both A and R are true and R is the correct explanation of A
• B. If both A and R are true, but R is not the correct explanation of A
• C. If A is true, but R is false
• D. If A is false, but R is true

Answer 1

Answer: (C)

Assertion is true, but Reason is false. Reason can be corrected as
Bundle sheath surrounds only vascular bundles of monocot leaf not in root and stem. The vascular bundles containing cambium are said to be open, but if no cambium develops, they are referred to as closed. In monocots, closed vascular bundles are found because of the absence of cambium.
