Cell wall shows

Options

A. Semipermeability
B. Differential permeability
C. Complete permeability
D. Impermeability

Answer

**Step-by-Step Solution:**

1. **Understanding the Cell Wall**: The cell wall is a rigid outer layer found in plant cells, fungi, and some bacteria. It provides structural support and protection to the cell.

2. **Comparison with Cell Membrane**: Unlike the cell membrane, which is selectively permeable, allowing only certain substances to pass through, the cell wall has different properties.

3. **Permeability Types**: There are various types of permeability:
- **Semi-permeability**: Allows some substances to pass while blocking others.
- **Differential permeability**: Similar to semi-permeability, but with more specific criteria for what can pass.
- **Complete permeability**: Allows all substances to pass without restriction.
- **Impermeability**: Does not allow any substances to pass through.

4. **Nature of Cell Wall**: The cell wall is known to be completely permeable, meaning it allows the passage of all types of molecules, including water and small proteins, without any restriction.

5. **Conclusion**: Based on the properties of the cell wall, the correct answer to the question "Cell wall shows" is **complete permeability**.
