The selectively permeable membrane of the cell is

Options

A. Plasmalemma
B. Cytoplasm
C. Cell wall
D. None of the above

Answer

To answer the question regarding the selectively permeable membrane of the cell, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the selectively permeable membrane of the cell. We need to identify which of the given options fits this description.

2. **Analyzing the Options**:
- **Option A: Plasma lemma**: This is another name for the plasma membrane, which surrounds the cell. It is known for its selective permeability, allowing certain substances to pass while blocking others.
- **Option B: Cytoplasm**: This is the jelly-like substance within the cell that contains organelles. It is not a membrane and does not have selective permeability.
- **Option C: Cell wall**: This is a rigid outer layer found in plant cells, fungi, and some bacteria. It provides structure and support but is not selectively permeable as it allows many substances to pass through.
- **Option D: None of the above**: This option suggests that none of the previous options are correct.

3. **Evaluating the Correct Answer**:
- The plasma lemma (or plasma membrane) is specifically designed to control what enters and exits the cell, making it selectively permeable.
- The cytoplasm and cell wall do not fit the definition of a selectively permeable membrane.

4. **Conclusion**: Based on the analysis, the correct answer is **Option A: Plasma lemma**.

### Final Answer:
The selectively permeable membrane of the cell is **A. Plasma lemma**.
