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 spaces found within the cytoplasm of plant cells. They play a crucial role in maintaining cell structure and function.

2. **Composition of Vacuoles**:
- The vacuole primarily contains **cell sap**, which is a solution of water, ions, sugars, and other substances. This cell sap is essential for maintaining turgor pressure within the plant cell, which helps keep the plant upright.

3. **Structure of Vacuoles**:
- The vacuole is surrounded by a membrane known as the **tonoplast**. The tonoplast regulates the movement of ions and other substances in and out of the vacuole, thus playing a significant role in cellular homeostasis.

4. **Other Components**:
- In addition to cell sap, vacuoles may also contain waste products and materials that are not useful for the cell. However, the primary component is the cell sap.

5. **Distinction from Other Organelles**:
- It's important to note that **stroma** refers to the fluid matrix found in chloroplasts, not in vacuoles. Therefore, stroma is not a component of the vacuole.

### Conclusion
The vacuole in a plant cell primarily contains **cell sap**, which includes water, nutrients, and waste products, and is surrounded by a membrane called the **tonoplast**.
