Three or less than six radial vascular bundles are present in

Options

A. Monocot stem
B. Dicot stem
C. Monocot root
D. Dicot root

Answer

**Step-by-Step Solution:**

1. **Understanding Vascular Bundles**: Vascular bundles are the arrangements of xylem and phloem in plants. They can be classified into two main types: conjoined and radial. Conjoined bundles have xylem and phloem located together, while radial bundles have them arranged separately.

2. **Identifying Types of Vascular Bundles**:
- **Conjoined Vascular Bundles**: Found in dicot stems, these bundles are arranged in a ring and are typically collateral and open.
- **Radial Vascular Bundles**: Found in roots, particularly in monocots and dicots, where xylem and phloem are arranged alternately.

3. **Analyzing Dicot and Monocot Roots**:
- **Monocot Roots**: These have radial vascular bundles, typically described as polyarch, with eight bundles of xylem and phloem.
- **Dicot Roots**: These also have radial vascular bundles, but they are described as having 2 to 6 bundles of xylem and phloem, arranged alternately.

4. **Conclusion**: The question asks for the presence of three or less than six radial vascular bundles. Based on the analysis, the dicot root fits this description as it has 2 to 6 bundles of xylem and phloem.

5. **Final Answer**: Therefore, three or less than six radial vascular bundles are present in the dicot root.
