Protoplast lacks

Options

A. Cytoplasm
B. Nucleus
C. Mitochondria
D. cell wall

Answer

To answer the question "Protoplast lacks," we will follow these steps:

### Step-by-Step Solution:

1. **Understanding Protoplast**:
- Protoplast refers to the living part of a cell, which includes the cytoplasm, the nucleus, and the cell membrane. It is essential for the cell to be considered living.

2. **Identifying Components of Protoplast**:
- The protoplast contains:
- Cytoplasm
- Nucleus
- Cell membrane
- These components are crucial for the cell's metabolic activities.

3. **Distinguishing Between Living and Dead Cells**:
- Living cells have protoplasts, while dead cells do not. This indicates that protoplasts are associated with the vitality of the cell.

4. **Considering the Cell Wall**:
- The cell wall is a rigid outer layer found in plant cells and bacteria but is absent in animal cells.
- Since the protoplast does not include the cell wall, we conclude that the protoplast lacks the cell wall.

5. **Final Conclusion**:
- Therefore, the correct answer to the question "Protoplast lacks" is the cell wall.

### Answer:
Protoplast lacks the cell wall.
