Function of collenchyma is -

Options

A. Photosynthesis
B. Mechanical support
C. Both
D. Secretion

Answer

### Step-by-Step Solution:

1. **Understanding Collenchyma**:
- Collenchyma is a type of plant tissue characterized by living cells that have thickened cell walls. These cells are typically found in the stems and leaves of plants.

2. **Cell Structure**:
- The cell walls of collenchyma are thickened at the corners due to the deposition of substances like cellulose, hemicellulose, or pectin. This unique structure allows collenchyma to provide support to the plant.

3. **Function of Collenchyma**:
- The primary function of collenchyma is to provide mechanical support to the growing parts of the plant. This support is crucial for young stems and leaves as they grow and develop.

4. **Other Functions**:
- Collenchyma does not play a role in photosynthesis or secretion. Its main role is to support the plant structure, especially in areas that are still growing.

5. **Conclusion**:
- Therefore, the correct answer to the question about the function of collenchyma is that it provides mechanical support.
