Vascular bundle is enclosed within a well developed sclerenchymatous sheath in

Options

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

Explanation

**Step-by-Step Solution:**

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

2. **Identifying the Sheath**: The question specifies that the vascular bundles are enclosed within a "well-developed sclerenchymatous sheath." Sclerenchyma is a type of plant tissue that provides support and strength due to its thick cell walls.

3. **Analyzing the Options**: The options provided are monocot stem, dicot stem, monocot root, and dicot root. We need to determine which of these has vascular bundles surrounded by a sclerenchymatous sheath.

4. **Monocot vs. Dicot**: In monocots (like grasses), the vascular bundles are typically scattered and are surrounded by a sclerenchymatous sheath. In contrast, in dicots, the vascular bundles are usually arranged in a ring and do not have a well-developed sclerenchymatous sheath.

5. **Conclusion**: Based on the characteristics of monocots and dicots, we can conclude that the vascular bundles enclosed within a well-developed sclerenchymatous sheath are found in the **monocot stem**.

**Final Answer**: Vascular bundles are enclosed within a well-developed sclerenchymatous sheath in the **monocot stem**.
