A cell with fully elastic wall is placed in hypertonic solution. What will not happwn ?

Options

A. Change in call size and shape
B. The whole cell will shrink
C. Cytoplam shrinks from the cell well and undergoes plasmolsis
D. Decrease in cell size .

Answer

To solve the question regarding a cell with a fully elastic wall placed in a hypertonic solution, we need to analyze the effects of hypertonic solutions on cells.

### Step-by-Step Solution:

1. **Understanding Hypertonic Solutions**:
- A hypertonic solution has a higher concentration of solutes compared to the inside of the cell. This means that the concentration of water outside the cell is lower than inside the cell.

2. **Effect on the Cell**:
- When a cell is placed in a hypertonic solution, water will move out of the cell to balance the solute concentrations. This process is called osmosis.

3. **Cell Size and Shape**:
- As water leaves the cell, the cell will lose volume, leading to a decrease in cell size. The cell may also change shape as it loses water.

4. **Plasmolysis**:
- In the case of a cell with a fully elastic wall, the cytoplasm may not adhere tightly to the cell wall. Therefore, while the cytoplasm will lose water and shrink, it will not separate from the cell wall in the same way it would in a rigid cell. This means that plasmolysis, which is the process where the cytoplasm shrinks away from the cell wall, will not occur.

5. **Conclusion**:
- Based on the above analysis, the option that states "Cytoplasm will shrink from the cell wall and undergo plasmolysis" is incorrect. Therefore, this is what will not happen when a cell with a fully elastic wall is placed in a hypertonic solution.

### Final Answer:
The correct answer is **C. Cytoplasm will shrink from the cell wall and undergo plasmolysis**.
