The bacterial cell wall is formed of :

Options

A. Cellulose
B. Hemicellulose
C. Both (a) and (c)
D. Peptidoglycan

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the composition of the bacterial cell wall. We need to identify the main component that forms this structure.

2. **Identifying the Major Component**: The bacterial cell wall is primarily composed of a substance known as peptidoglycan. This is a crucial element that provides structural integrity to the cell wall.

3. **Characteristics of Peptidoglycan**: Peptidoglycan is a rigid structure that is unique to prokaryotic cells (bacteria). It not only gives shape to the bacterial cell but also surrounds the cytoplasmic membrane, providing protection and support.

4. **Excluding Other Options**: In the context of the question, we can eliminate other potential components such as cellulose and hemicellulose, which are not found in bacterial cell walls.

5. **Conclusion**: Based on the information gathered, we conclude that the bacterial cell wall is formed of peptidoglycan. Therefore, the correct answer is option 4: peptidoglycan.
