Cell sap is

Options

A. a dilute solution of minerals and some organic substances in the vacuole.
B. a dilute solution of minerals in water absorbed by the plant from the soil .
C. exudate from the cell
D. a solution of different organic substances dissolved in the cytoplasm.

Answer

### Step-by-Step Solution:

1. **Understanding Cell Structure**:
- Begin by recognizing that plant cells have a distinct structure, which includes a large central vacuole that occupies a significant portion of the cell's interior.

2. **Identifying the Vacuole**:
- The central vacuole is an empty space within the plant cell that serves as a storage area. It is crucial for maintaining the cell's turgor pressure and storing various substances.

3. **Composition of Cell Sap**:
- Cell sap is primarily composed of a dilute solution of minerals and some organic substances. This mixture is stored within the vacuole.

4. **Role of Water and Minerals**:
- Water absorbed by the plant from the soil carries dissolved minerals and organic substances. These components accumulate in the vacuole, contributing to the composition of cell sap.

5. **Evaluating the Options**:
- Assess the provided options:
- Option A: "A dilute solution of minerals and some organic substance in the vacuole" - This is correct as it accurately describes cell sap.
- Option B: "A dilute solution in the water absorbed by the plant from the soil" - This is incorrect as it does not specify the role of the vacuole.
- Option C: "Exudate from the cell" - This is incorrect as exudate refers to substances secreted by cells, not stored within the vacuole.
- Option D: "A solution of different organic substances dissolved in the cytoplasm" - This is incorrect as cell sap is not found in the cytoplasm but in the vacuole.

6. **Conclusion**:
- Based on the analysis, the correct answer is that cell sap is "a dilute solution of minerals and some organic substance in the vacuole."
