Options

A. Little solute potential
B. Maximum turgor pressure
C. Zero turgor pressure
D. Negative turgor pressure.

Answer

To answer the question "A freshly plasmolyzed cell has," we need to understand the concept of plasmolysis and the conditions of a cell placed in a hypertonic solution. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Understanding Plasmolysis**:
- Plasmolysis occurs when a cell is placed in a hypertonic solution, which has a higher concentration of solutes compared to the inside of the cell. As a result, water moves out of the cell to balance the concentration gradient.

2. **Effect on Cell Structure**:
- As water leaves the cell, the plasma membrane pulls away from the cell wall, creating a space between the cell wall and the plasma membrane. This condition is referred to as plasmolysis.

3. **Solute Potential**:
- In a freshly plasmolyzed cell, the concentration of solutes inside the cell increases because water has exited. Therefore, the solute potential (Ψs) inside the cell becomes more negative, indicating a higher solute concentration.

4. **Turgor Pressure**:
- Turgor pressure is the pressure exerted by the fluid (water) inside the cell against the cell wall. In a freshly plasmolyzed cell, turgor pressure is not present or is very low because the cell has lost water. This results in a negative turgor pressure, as the cell wall is no longer being pushed outward by the internal pressure of the cell.

5. **Conclusion**:
- Therefore, a freshly plasmolyzed cell has a maximum solute potential (due to increased solute concentration) and negative turgor pressure (due to the retraction of the plasma membrane from the cell wall).

### Final Answer:
A freshly plasmolyzed cell has maximum solute potential and negative turgor pressure.
