The property of semipermeability belongs to

Options

A. cell wall
B. plasma membrane
C. mitochondria only
D. none of the above

Explanation

### Step-by-Step Solution:

1. **Understanding Semi-permeability**:
- Semi-permeability refers to the property of a membrane that allows certain molecules to pass through while restricting others. This means that not all substances can freely cross the membrane; only specific ones can.

**Hint**: Remember that semi-permeability is selective, allowing only certain molecules to pass.

2. **Identifying the Options**:
- The options given are:
- A) Cell wall
- B) Plasma membrane
- C) Mitochondria
- D) None of the above

**Hint**: List out the characteristics of each option to see which one fits the definition of semi-permeability.

3. **Analyzing the Cell Wall**:
- The cell wall is found in plants and bacteria and is known to be completely permeable. This means it allows all types of molecules to pass through without restriction.

**Hint**: Think about the function of the cell wall and whether it selectively allows molecules through.

4. **Analyzing the Plasma Membrane**:
- The plasma membrane is a lipid bilayer that is amphipathic in nature. It allows only certain small non-polar and some small polar molecules to pass through, making it semi-permeable.

**Hint**: Consider the structure of the plasma membrane and how it interacts with different types of molecules.

5. **Analyzing Mitochondria**:
- While mitochondria have membranes, they are not referred to as having a semi-permeable membrane in the same context as the plasma membrane. The outer membrane of mitochondria is more permeable than the inner membrane, which is selectively permeable.

**Hint**: Compare the permeability of mitochondrial membranes to that of the plasma membrane.

6. **Conclusion**:
- Based on the analysis, the plasma membrane is the only structure among the options that exhibits the property of semi-permeability.

**Final Answer**: The property of semi-permeability belongs to **B) Plasma membrane**.
