Vascular bundles where the phloem is found to be present on both sides of xylem is said to be

Options

A. radial
B. conjoint
C. collateral
D. bicollateral

Answer

To solve the question regarding the type of vascular bundle where the phloem is present on both sides of the xylem, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Vascular Bundles**: Vascular bundles are structures in plants that consist of xylem and phloem, which are responsible for the transport of water, nutrients, and food.

2. **Identify the Arrangement**: The question specifies that phloem is present on both sides of the xylem. This means that if you visualize the arrangement, xylem is in the center, and phloem is on both the left and right sides.

3. **Define the Types of Vascular Bundles**:
- **Radial Vascular Bundle**: In this type, xylem and phloem are located on different radii, meaning they are not on the same line.
- **Conjoined Vascular Bundle**: Here, the phloem is located outside the xylem on the same radius.
- **Collateral Vascular Bundle**: In this case, phloem is on the inner side and xylem on the outer side, but both are on the same radius.
- **Bicollateral Vascular Bundle**: This is the type where phloem is present on both sides of the xylem.

4. **Conclusion**: Based on the arrangement described in the question, where phloem is on both sides of xylem, the correct answer is **bicollateral vascular bundle**.

### Final Answer:
The vascular bundles where the phloem is found to be present on both sides of xylem is said to be **bicollateral**.
