Hypodermis is collenchymatous in

Options

A. Monocot root
B. Sunflower stem
C. Monocot stem
D. dicot root

Answer

To determine where the hypodermis is collenchymatous, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Hypodermis**: The hypodermis is a layer of tissue located beneath the cuticle of plants. It plays a role in supporting the plant structure.

2. **Identify the Types of Plant Tissues**: The hypodermis can be made up of different types of tissues, primarily collenchyma and sclerenchyma.
- **Collenchyma**: This tissue provides flexibility and support, especially in young stems and leaves.
- **Sclerenchyma**: This tissue is more rigid and provides structural support, often found in mature tissues.

3. **Determine the Context**: The question asks specifically about the hypodermis being collenchymatous. This characteristic is typically found in dicot stems.

4. **Examine the Options**:
- **Monocot Root**: The hypodermis is sclerenchymatous. (Incorrect)
- **Sunflower Stem**: Sunflower is a dicot, and its hypodermis is collenchymatous. (Correct)
- **Monocot Stem**: The hypodermis is sclerenchymatous. (Incorrect)
- **Dicot Root**: The hypodermis is sclerenchymatous. (Incorrect)

5. **Conclusion**: Based on the analysis, the only option where the hypodermis is collenchymatous is the sunflower stem, which is a dicot stem.

### Final Answer:
The hypodermis is collenchymatous in the **sunflower stem** (option 2).
