Question

Arrange the following organs with a gradual increase in the number of vascular bundles in them.
I. Monocot Root II. Monocot stem
III. Dicot root

• A. III, I, II
• B. II, I, III
• C. I, III, II
• D. I, II, III

Answer 1

The correct option is A III, I, II

The number of vascular bundles in the dicot root is two to four (diarch to tetrarch condition).
The number of vascular bundles in the monocot root is more than six (polyarch condition).

In the monocot stem, there are a large number of vascular bundles scattered throughout the ground tissue.
Monocot stem has more number of vascular bundles followed by monocot root and then the dicot root.

Dicot root < Monocot root < Monocot stem.
