Hypodermis provides mechanical support in

Options

A. 1)Dicot root
B. 2)Dicot stem
C. 3)Monocot root
D. 4)All the above

Answer

**Step-by-Step Solution:**

1. **Understanding Hypodermis**: The hypodermis is a layer of cells located just beneath the epidermis of plant tissues. It plays a crucial role in providing mechanical support and protection to the plant.

2. **Identifying the Composition**: The hypodermis is primarily made up of collenchyma cells. These cells are characterized by their thickened cell walls, which contribute to the structural integrity of the plant.

3. **Function of Hypodermis**: The main function of the hypodermis is to provide mechanical support to the plant. This is particularly important in areas that experience mechanical stress or need additional support to maintain their structure.

4. **Analyzing the Options**: The question provides four options regarding where the hypodermis provides mechanical support:
- Dicot root
- Dicot stem
- Monocot root
- All of the above

5. **Evaluating Each Option**:
- **Dicot Root**: The hypodermis is not typically present in dicot roots; instead, the cortex serves this function.
- **Dicot Stem**: In dicot stems, the hypodermis is present and composed of collenchyma cells, which provide mechanical support.
- **Monocot Root**: Similar to dicot roots, monocot roots do not have a hypodermis that provides mechanical support.
- **All of the Above**: Since only the dicot stem has a hypodermis providing mechanical support, this option is incorrect.

6. **Conclusion**: Based on the analysis, the correct answer is that the hypodermis provides mechanical support in the **Dicot Stem**.

**Final Answer**: Dicot Stem (Option 2)
