The common character in both dicot root and monocot root is the presence of

Options

A. Large Medulla
B. Polyarch xylem
C. Cambial development at later stages
D. Radial vascular bundles

Answer

To determine the common character in both dicot and monocot roots, we need to analyze the structures present in each type of root and compare them.

### Step-by-Step Solution:

1. **Understanding Dicot and Monocot Roots**:
- Dicot roots typically have a smaller pith or medulla, while monocot roots have a larger pith or medulla.

2. **Xylem Structure**:
- In dicot roots, the xylem is usually arranged in a way that there are 2 to 6 xylem strands.
- In monocot roots, the xylem is referred to as polyarch, meaning it has more than 6 xylem strands.

3. **Cambial Layer**:
- Dicot roots have a cambial layer that develops at later stages, while monocot roots do not have this cambial layer.

4. **Analyzing the Options**:
- **Option A: Large Medulla** - This is present in monocots but not in dicots, so this option is incorrect.
- **Option B: Polyarch Xylem** - This is characteristic of monocots only, so this option is also incorrect.
- **Option C: Cambial Development at Later Stages** - This is present in dicots but absent in monocots, making this option incorrect as well.
- **Option D: Radial Vascular Bundle** - This structure is present in both dicot and monocot roots, where xylem and phloem are arranged in a radial pattern.

5. **Conclusion**:
- The common character in both dicot and monocot roots is the presence of **radial vascular bundles**.

### Final Answer:
The common character in both dicot root and monocot root is the presence of **radial vascular bundles**.
