Which is not function of vacuoles in plant cell ?

Options

A. Storage
B. Waste disposal
C. Production of `H_(2)O_(2)`
D. Cell elongation and protection

Answer

### Step-by-Step Solution:

1. **Understanding Vacuoles**:
- Vacuoles are bag-like structures found within plant cells. They play various roles in maintaining the cell's health and functionality.

2. **Functions of Vacuoles**:
- **Waste Disposal**: Vacuoles act as storage for waste materials that the cell needs to expel. They collect harmful substances and help in detoxifying the cell.
- **Storage of Nutrients and Minerals**: Vacuoles store essential nutrients, minerals, and other substances that the plant cell may need.
- **Water Regulation**: They help in maintaining water balance within the cell by storing excess water and releasing it when necessary. This is crucial for maintaining turgidity and rigidity in plant cells.
- **Osmotic Potential Maintenance**: Vacuoles contribute to the osmotic potential of the cell, which is important for cell elongation and overall plant growth.

3. **Identifying the Incorrect Function**:
- The question asks for the function that is **not** associated with vacuoles.
- Among the functions listed, the production of hydrogen peroxide (H2O2) is not a function of vacuoles. Instead, this is typically associated with other cellular organelles like peroxisomes.

4. **Conclusion**:
- Therefore, the correct answer to the question "Which is not a function of vacuoles in plant cells?" is the **production of H2O2**.
