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. **Understand Parenchyma**: Parenchyma is a type of simple permanent tissue in plants. It is composed of a single type of cell and is involved in various functions.

2. **Identify Functions of Parenchyma**: The major functions of parenchyma include:
- **Photosynthesis**: Some parenchyma cells contain chloroplasts and are involved in the process of photosynthesis.
- **Storage of Food**: Parenchyma cells often store starch, oils, and water, making them crucial for food storage in plants.
- **Secretion**: Parenchyma can also be involved in the secretion of substances.

3. **Evaluate the Options**: The question asks which option is NOT a function of parenchyma. The options provided include:
- Translocation of food
- Storage of food
- Mechanical support
- Photosynthesis

4. **Analyze Each Option**:
- **Translocation of Food**: This is primarily a function of phloem, not parenchyma.
- **Storage of Food**: This is a function of parenchyma.
- **Mechanical Support**: This is provided by collenchyma and sclerenchyma, not parenchyma.
- **Photosynthesis**: This can be a function of parenchyma in green tissues.

5. **Conclusion**: The option that is NOT a function of parenchyma is **mechanical support**.

**Final Answer**: Mechanical support is NOT a function of parenchyma.
