Read the following statements about monocot root. Which amongest them are correct?
I. It shows a polyarch condition of xylem.
II. Central pith is less or absent.
III. The monocot root does not undergo secondary growth.

Options

A. Only I
B. I, II and III
C. I and III
D. I and II

Answer

To determine which statements about monocot roots are correct, let's analyze each statement one by one.

### Step 1: Analyze Statement I
**Statement I: It shows a polyarch condition of xylem.**

- **Explanation:** The term "polyarch" refers to a root structure that has more than two xylem bundles. In monocot roots, it is indeed common to find multiple xylem bundles, typically more than two. Therefore, this statement is correct.

### Step 2: Analyze Statement II
**Statement II: Central pith is less or absent.**

- **Explanation:** Monocot roots typically have a central pith that is well-developed. The pith is not absent; rather, it can be prominent in many monocot species. Therefore, this statement is incorrect.

### Step 3: Analyze Statement III
**Statement III: The monocot root does not undergo secondary growth.**

- **Explanation:** Monocot roots generally do not undergo secondary growth. This is because they lack a vascular cambium, which is necessary for the production of secondary xylem and phloem. Therefore, this statement is correct.

### Conclusion
Based on the analysis:
- **Correct Statements:** I and III
- **Incorrect Statement:** II

The correct options are **1 and 3**.
