Which plants part possesses polyarch condition of vasuclar bundles with a well developed pith?

Options

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

Answer

To determine which plant part possesses a polyarch condition of vascular bundles with a well-developed pith, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Polyarch Condition**: This refers to the presence of more than four vascular bundles.
- **Vascular Bundles**: These are the structures that contain xylem and phloem, responsible for the transport of water, nutrients, and food in plants.
- **Well-Developed Pith**: The pith is the central part of the stem or root, typically composed of parenchyma cells.

2. **Identify the Plant Parts**:
- The question provides four options: dicot root, monocot root, dicot stem, and monocot stem.

3. **Analyze Each Option**:
- **Dicot Root**: Typically has a tetrarch or pentarch condition of vascular bundles and does not usually have a well-developed pith.
- **Monocot Root**: Generally exhibits a polyarch condition of vascular bundles and has a well-developed pith.
- **Dicot Stem**: Usually has a ring of vascular bundles and does not exhibit a polyarch condition.
- **Monocot Stem**: Contains scattered vascular bundles and does not have a well-developed pith.

4. **Conclusion**:
- Based on the analysis, the plant part that possesses a polyarch condition of vascular bundles with a well-developed pith is the **monocot root**.

### Final Answer:
The part of the plant that possesses a polyarch condition of vascular bundles with a well-developed pith is the **monocot root**.
