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.
Reason (R) : The ground tissue in a monocotyledonous stem is highly differentiated into cortex, endodermis, pericycle, and pith.
Options
- ABoth Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A)
- BBoth Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A)
- CAssertion (A) is true but Reason (R) is false
- 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
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
