In radial vascular bundles the xylem and phloem lie

Options

A. Xylem and phloem are on same radius
B. Xylem and phloem are on alternating with each other
C. Xylem and phloem are separated by meristem (cambium) barate radii
D. Xylem and phloem are one around the other

Answer

### Step-by-Step Solution:

1. **Understanding Radial Vascular Bundles**:
- Radial vascular bundles are a type of vascular arrangement in plants. In these bundles, the xylem and phloem are arranged in a specific manner.

2. **Arrangement of Xylem and Phloem**:
- In radial vascular bundles, the xylem and phloem are located at different radii from the center of the bundle. This means that they are not located on the same radius.

3. **Separation by Non-Conductive Tissue**:
- The xylem and phloem are separated by non-conductive tissues. This separation allows for the distinct functioning of xylem (water transport) and phloem (nutrient transport).

4. **Alternating Arrangement**:
- The xylem and phloem alternate with each other. This means that if you were to look at the cross-section of a radial vascular bundle, you would see xylem and phloem positioned alternately around the center.

5. **Conclusion**:
- Therefore, in radial vascular bundles, the xylem and phloem lie separately and alternate with each other.

### Final Answer:
In radial vascular bundles, the xylem and phloem lie alternately with each other, separated by non-conductive tissues.
