Which of the following is not correctly matched for the organism and its cell wall degrading enzyme?

Options

A. Algae - Methylase
B. Fungi - Chitinase
C. Bacteria - Lysozyme
D. Plant cells - Cellulase

Answer

To solve the question of which organism and its cell wall degrading enzyme is not correctly matched, we will analyze each option provided.

### Step-by-Step Solution:

1. **Analyze Option A: Alga and Methylase**
- Algal cell walls are primarily made of cellulose.
- The enzyme that degrades cellulose is cellulase, not methylase.
- **Conclusion**: This option is incorrectly matched.

2. **Analyze Option B: Fungi and Chitinase**
- Fungal cell walls are made of chitin.
- The enzyme that degrades chitin is chitinase.
- **Conclusion**: This option is correctly matched.

3. **Analyze Option C: Bacteria and Lysozyme**
- Bacterial cell walls are made of peptidoglycan.
- The enzyme that degrades peptidoglycan is lysozyme.
- **Conclusion**: This option is correctly matched.

4. **Analyze Option D: Plant Cells and Cellulase**
- Plant cell walls are also made of cellulose.
- The enzyme that degrades cellulose is cellulase.
- **Conclusion**: This option is correctly matched.

### Final Conclusion:
The only option that is not correctly matched is **Option A: Alga and Methylase**.
