Options

A. cytoplasm
B. vacuole
C. nucleus
D. Mitochondrioa

Answer

**Step-by-Step Solution:**

1. **Understanding Tonoplast**: The question asks about the Tonoplast, which is a specific type of membrane. It is important to know what Tonoplast is and its function.

2. **Identifying the Structure**: The Tonoplast is a semi-permeable membrane. This means it allows certain substances to pass through while blocking others.

3. **Location of Tonoplast**: The Tonoplast surrounds a specific structure within the cell. This structure is known as the vacuole.

4. **Function of Vacuole**: The vacuole is a membrane-bound space within the cytoplasm of plant cells. It serves multiple functions, including storage of substances.

5. **Contents of Vacuole**: The vacuole typically contains water, cell sap, excretory materials, and other substances that are not useful for the cell.

6. **Conclusion**: Therefore, the Tonoplast is the membrane that surrounds the vacuole in plant cells.

**Final Answer**: Tonoplast is a membrane surrounding the vacuole.
