Which is not a function of parenchyma ?

Options

A. Photosynthesis
B. Translocation of food
C. Storge
D. Mechanical support

Answer

### Step-by-Step Solution:

1. **Identify the Types of Tissues**: Understand that parenchyma is a type of simple permanent tissue, which consists of only one type of cell.

2. **List Functions of Parenchyma**: Recognize the primary functions of parenchyma tissue:
- **Photosynthesis**: Some parenchyma cells contain chloroplasts and can perform photosynthesis.
- **Storage**: Parenchyma cells are involved in the storage of starch, oils, and water.
- **Translocation of Food**: Parenchyma can assist in the movement of nutrients and food within the plant.

3. **Analyze the Options**: Review the options given in the question:
- Photosynthesis
- Translocation of food
- Storage
- Mechanical support

4. **Determine the Incorrect Function**: Compare the functions of parenchyma with the options:
- Photosynthesis: Yes, parenchyma can perform this.
- Translocation of food: Yes, parenchyma can assist in this.
- Storage: Yes, parenchyma is involved in storage.
- Mechanical support: This is primarily the function of collenchyma and sclerenchyma, not parenchyma.

5. **Select the Correct Answer**: Conclude that the function that is not associated with parenchyma is **mechanical support**.

### Final Answer:
The function that is not associated with parenchyma is **mechanical support**.
