The type of vascular bundle in which xylem and phloem are situated at same redius, is called

Options

A. concentric
B. spiral
C. radial
D. conjoint

Answer

To solve the question regarding the type of vascular bundle in which xylem and phloem are situated at the same radius, we can follow these steps:

### Step-by-Step Solution:

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

2. **Identify Types of Vascular Bundles**: Vascular bundles can be classified based on the arrangement of xylem and phloem. The two main types are:
- Radial Vascular Bundles
- Conjoined Vascular Bundles

3. **Define Radial Vascular Bundles**: In radial vascular bundles, xylem and phloem are arranged alternately, meaning they are located at different radii from the center of the bundle. This type is typically found in the roots of dicots and monocots.

4. **Define Conjoined Vascular Bundles**: In conjoined vascular bundles, xylem and phloem are located at the same radius from the center of the bundle. This arrangement allows for more efficient transport and is commonly found in the stems and leaves of dicots and monocots.

5. **Conclusion**: Since the question specifically asks for the type of vascular bundle where xylem and phloem are situated at the same radius, the correct answer is **Conjoined Vascular Bundle**.

### Final Answer:
The type of vascular bundle in which xylem and phloem are situated at the same radius is called **Conjoined Vascular Bundle**.
