One of the major components of cell wall of most fungi is:

Options

A. Chitin
B. Peptidoglycan
C. Cellulose
D. Hemicellulose

Answer

**Step-by-Step Solution:**

1. **Identify the Components of Fungal Cell Walls:**
- The question asks for a major component of the cell wall of most fungi. Fungal cell walls are primarily composed of specific substances that provide structure and rigidity.

2. **Consider the Options Provided:**
- The options given are chitin, peptidoglycan, cellulose, and hemicellulose. We need to evaluate each of these to determine which is the correct answer.

3. **Evaluate Each Option:**
- **Chitin:** This is a polysaccharide that is a major component of the cell walls of fungi. It provides structural support and rigidity.
- **Peptidoglycan:** This is primarily found in the cell walls of bacteria, not fungi, so it can be eliminated.
- **Cellulose:** This is a major component of plant cell walls, not fungi, so it is also incorrect.
- **Hemicellulose:** This is found in plant cell walls but is not a major component of fungal cell walls.

4. **Conclusion:**
- Based on the evaluation, the correct answer is **chitin**. It is the primary component that gives fungi their structural integrity.

5. **Final Answer:**
- The major component of the cell wall of most fungi is **chitin**.
