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

Options

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

Answer

To solve the question regarding which organism is not correctly matched with its cell wall degrading enzyme, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: We need to identify which of the provided options incorrectly matches an organism with its corresponding cell wall degrading enzyme.

2. **Analyze Each Option**:
- **Option 1**: Plant cell and cellulase.
- **Analysis**: This is correct. Cellulase is the enzyme that degrades cellulose, which is a major component of plant cell walls.

- **Option 2**: Algae and methylase.
- **Analysis**: This is incorrect. The correct enzyme for degrading algal cell walls is not methylase; it is PMCS (Pectin Methylesterase). Methylase is involved in adding methyl groups to DNA, not in degrading cell walls.

- **Option 3**: Fungi and chitinase.
- **Analysis**: This is correct. Chitinase is the enzyme that degrades chitin, which is found in the cell walls of fungi.

- **Option 4**: Bacteria and lysozyme.
- **Analysis**: This is correct. Lysozyme is an enzyme that degrades peptidoglycan in bacterial cell walls.

3. **Identify the Incorrect Match**: From the analysis, we see that Option 2 (Algae and methylase) is not correctly matched.

4. **Conclusion**: The answer to the question is Option 2.

### Final Answer:
**Option 2: Algae and methylase is not correctly matched.**
