Hypodermis of dicot stem is made up of

Options

A. Parenchymatous cells
B. Collenchymatous cells
C. Sclerenchymatous cells
D. Prosenchymatous cells

Answer

### Step-by-Step Solution

1. **Understanding the Structure**: The hypodermis is a layer found beneath the epidermis in the stems of dicotyledonous plants (dicots). It plays a crucial role in providing support to the plant.

2. **Identifying Cell Types**: The cells that make up the hypodermis can vary, but in dicot stems, they are primarily composed of specific types of cells. The options provided in the question include:
- Cholenchyma
- Parenchyma
- Sclerenchyma

3. **Analyzing the Options**:
- **Cholenchyma**: These are living cells that provide flexible support due to their thickened cell walls.
- **Parenchyma**: These are also living cells, typically involved in storage and metabolic functions, but they do not provide significant structural support.
- **Sclerenchyma**: These are dead cells that provide rigid support but are not found in the hypodermis of dicot stems.

4. **Correct Identification**: The hypodermis of dicot stems is primarily made up of **cholenchyma** cells. These cells are characterized by their angular thickening and lack of intercellular spaces, making them compactly arranged.

5. **Conclusion**: Therefore, the correct answer to the question is that the hypodermis of dicot stems is made up of **cholenchyma**.
