In dicot root

Options

A. Vacscular bundles are scattered with cambium
B. Vascular bundles are open and arranged in a ring
C. Xylem and pholem are radial
D. Xylem is always endarch

Answer

### Step-by-Step Solution:

1. **Understanding Dicot Roots**:
- Dicot roots are characterized by their vascular bundles. Unlike monocot roots, the vascular bundles in dicot roots are arranged in a specific pattern.

2. **Vascular Bundle Arrangement**:
- In dicot roots, the vascular bundles are arranged radially. This means that the xylem and phloem are positioned alternately around the central axis of the root.

3. **Tetrarch Arrangement**:
- The vascular bundles in dicot roots are often described as tetrarch, meaning there are four groups of xylem and phloem. This arrangement allows for efficient transport of water and nutrients.

4. **Position of Xylem and Phloem**:
- In a typical dicot root, the xylem is located at the center, while the phloem surrounds the xylem. This central placement of xylem is a distinguishing feature of dicot roots.

5. **Conclusion**:
- Based on the characteristics discussed, the correct answer to the question about dicot roots is that the xylem and phloem are arranged radially.

### Final Answer:
- The correct option is **C**: Xylem and phloem are radial.
