Which part of the cell can contain N- acetylglucosamine

Options

A. Cell envelope
B. Cell wall
C. Nucleus
D. Ribosomes.

Answer

To determine which part of the cell can contain N-acetylglucosamine, we can follow these steps:

### Step-by-Step Solution:

1. **Understand N-acetylglucosamine**: N-acetylglucosamine is a derivative of glucose and is an important component in various biological structures, particularly in the cell walls of certain organisms.

2. **Identify the Cell Parts**: The question provides several options: cell envelope, cell wall, nucleus, and ribosome. We need to analyze each part to see where N-acetylglucosamine might be found.

3. **Evaluate the Cell Wall**: In prokaryotic cells, the cell wall is primarily composed of peptidoglycan, which contains N-acetylglucosamine as one of its building blocks. This makes the cell wall a significant structure that contains N-acetylglucosamine.

4. **Consider the Other Options**:
- **Cell Envelope**: This term generally refers to the outer layers of a prokaryotic cell, which includes the cell wall and the plasma membrane. While it includes the cell wall, it is not specific to N-acetylglucosamine.
- **Nucleus**: Prokaryotic cells do not have a true nucleus; they have a nucleoid region instead. Therefore, this option cannot contain N-acetylglucosamine.
- **Ribosome**: Ribosomes are the sites of protein synthesis and do not contain N-acetylglucosamine.

5. **Conclusion**: Based on the analysis, the part of the cell that contains N-acetylglucosamine is the **cell wall**.

### Final Answer:
The correct option is the **cell wall**.
