Vascular bundle is enclosed within a well developed sclerechymatous sheath in

Options

A. monocot stem
B. dicot stem
C. monocot root
D. dicot dicot

Explanation

To solve the question "Vascular bundle is enclosed within a well-developed sclerechymatous sheath in," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Vascular Bundles**:
- Vascular bundles are the part of the plant that contains xylem and phloem, responsible for the transport of water, nutrients, and food.

2. **Identifying the Structure**:
- The question asks about the presence of a "well-developed sclerechymatous sheath" around the vascular bundles. Sclerenchyma is a type of supportive tissue in plants that provides strength and rigidity.

3. **Examining Plant Parts**:
- Vascular bundles can be found in various parts of the plant, but their arrangement differs between roots and stems. In roots, the arrangement is radial, while in stems, the arrangement can be conjoined.

4. **Types of Plants**:
- Vascular bundles can be classified based on whether they are found in monocots or dicots. Dicot vascular bundles can be open or closed, while monocot vascular bundles are typically closed.

5. **Sclerenchyma Presence**:
- In monocots, the vascular bundles are often surrounded by a sclerenchymatous sheath that provides additional support. In contrast, in dicots, the sclerenchyma may not form a well-developed sheath around the vascular bundles.

6. **Conclusion**:
- Based on the information, we can conclude that vascular bundles enclosed within a well-developed sclerechymatous sheath are found in the stems of monocots.

### Final Answer:
Vascular bundles are enclosed within a well-developed sclerechymatous sheath in **monocot stems**.
