Well developed pith is seen in

Options

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

Answer

To solve the question "Well developed pith is seen in," we will analyze the characteristics of pith in different types of plants.

### Step-by-Step Solution:

1. **Understanding Pith**:
- Pith is a tissue found in the center of the vascular bundles in plants. It is primarily composed of parenchyma cells and serves various functions, including storage and support.

2. **Identifying Plant Types**:
- There are two main types of flowering plants: monocots (monocotyledons) and dicots (dicotyledons). Each type has distinct structural characteristics.

3. **Analyzing Monocot Roots and Stems**:
- In monocot roots, the vascular bundles are arranged in a scattered manner, and the pith is not well-developed.
- In monocot stems, the pith is also not well-developed due to the scattered arrangement of vascular bundles.

4. **Analyzing Dicot Roots and Stems**:
- In dicot roots, the vascular bundles are arranged in a ring, and there is typically a well-developed pith.
- In dicot stems, the pith is also well-developed, as the vascular bundles are arranged in a ring, allowing for a larger central pith.

5. **Conclusion**:
- The well-developed pith is found in both monocot roots and dicot stems. Therefore, the correct answer to the question is option 3: monocot root and dicot stem.

### Final Answer:
The well-developed pith is seen in monocot roots and dicot stems.
