The vacuole in the plant cell contains

Options

A. stroma
B. matrix
C. tonoplast
D. cell sap

Answer

### Step-by-Step Solution:

1. **Understanding Vacuoles**:
- Vacuoles are membrane-bound sacs found in the cytoplasm of plant cells. They play a crucial role in storing various substances.

2. **Composition of Vacuoles**:
- The vacuole in plant cells is filled with a fluid known as cell sap. This cell sap contains a variety of substances including minerals, sugars, amino acids, proteins, pigments, and waste products.

3. **Identifying the Tonoplast**:
- The vacuole is surrounded by a membrane called the tonoplast. This membrane regulates the movement of substances in and out of the vacuole.

4. **Evaluating the Options**:
- **Trauma**: This is not related to vacuoles.
- **Matrix**: This term refers to the inner space of mitochondria, not vacuoles.
- **Tonoplast**: This is the correct term for the membrane surrounding the vacuole.
- **Cell Sap**: While this is the fluid contained within the vacuole, it is not the name of the vacuole itself.

5. **Conclusion**:
- The vacuole in the plant cell contains cell sap, and it is surrounded by the tonoplast. However, if the question is asking for what the vacuole itself is surrounded by, the answer would be tonoplast.

### Final Answer:
The vacuole in the plant cell contains **cell sap**, and it is surrounded by the **tonoplast**.
