The correct Answer is:
To determine which statements about monocot roots are correct, let's analyze each statement step by step. ### Step 1: Analyze Statement I **Statement I:** "It shows a polyarch condition of xylem." - In monocot roots, the xylem is typically arranged in multiple bundles, which is referred to as a polyarch condition. This means that there are several groups of xylem vessels present. - **Conclusion:** This statement is **correct**. ### Step 2: Analyze Statement II **Statement II:** "Central pith is less or absent." - Monocot roots usually have a well-developed central pith that is often large and prominent. The pith is not absent; rather, it is a significant part of the root structure. - **Conclusion:** This statement is **incorrect**. ### Step 3: Analyze Statement III **Statement III:** "The monocot root does not undergo secondary growth." - Monocot roots typically do not exhibit secondary growth, which is the increase in thickness due to the activity of the cambium. Secondary growth is more common in dicots. - **Conclusion:** This statement is **correct**. ### Final Conclusion Based on the analysis: - Statement I is correct. - Statement II is incorrect. - Statement III is correct. Thus, the correct statements about monocot roots are **I and III**.
