Assertion. In collateral vascular bundles, phloem is situated towards inner side.
Reason. In monocot stem, cambium is present

• A. A
• B. B
• C. C
• D. D

Answer 1

Answer: (D)

D

The common arrangement of vascular tissues is collateral, i.e. the primary xylem is located on the inner side of the bundle, and the primary phloem is located on the outer side of the bundle. Monocot stems, such as corn, palms and bamboos, do not have a vascular cambium and do not exhibit secondary growth by the production of concentric annual rings.

So, the correct answer is 'D.'
