Question

Out of the following, how many features belong to monocot root?
1. Radial vascular bundles
2. Closed vascular bundles
3. Endodermis absent
4. Pith developed
5. Polyarch condition

• A. One
• B. Two
• C. Three
• D. Four

Answer 1

The correct option is D Four

When xylem and phloem within a vascular bundle are arranged in an alternate manner on different radii, then it is called Radial vascular bundles. It is true for monocot roots.

When there is no cambium present between the xylem and phloem elements, the bindle is said to be Closed vascular bundles.It is true for monocot roots.

Endodermis is very distinct in monocot root.Hence, sentence number 3 does not belong to the features of monocot root.

Pith is large and well developed in roots of monocotyledonous plants.

Monocot root comprises of more than six xylem bundles i.e. Polyarch condition.

So, the correct option is 'Four'
