Which is not correctly matched organisms and its cell wall degrading enzyme

Options

A. Fungi - chitinase
B. Bacteria - lysozyme
C. Plant cells - cellulase
D. Algae - methylase

Answer

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

### Step-by-Step Solution:

1. **Identify the Organisms and Enzymes**:
We need to look at the organisms mentioned and the enzymes associated with them. The organisms typically discussed in this context are fungi, bacteria, plants, and algae.

2. **Fungi and Chitinase**:
- **Fungi**: The cell wall of fungi is primarily made of chitin.
- **Enzyme**: Chitinase is the enzyme that degrades chitin.
- **Match**: This match is correct.

3. **Bacteria and Lysozyme**:
- **Bacteria**: The cell wall of bacteria is mainly composed of peptidoglycan.
- **Enzyme**: Lysozyme is known to degrade peptidoglycan in bacterial cell walls.
- **Match**: This match is also correct.

4. **Plants and Cellulase**:
- **Plants**: The cell wall of plants is primarily made of cellulose.
- **Enzyme**: Cellulase is the enzyme that breaks down cellulose.
- **Match**: This match is correct as well.

5. **Algae and Methylase**:
- **Algae**: The cell wall composition can vary but often includes components like cellulose, glycoproteins, and other polysaccharides.
- **Enzyme**: Methylase is not typically known as a cell wall degrading enzyme for algae.
- **Correct Enzymes**: Algal cell walls can be degraded by enzymes such as chitinase, lysozyme, pectinase, sulfatase, or laminarinase.
- **Match**: This match is incorrect.

### Conclusion:
The organism and enzyme that is not correctly matched is **Algae and Methylase**. Therefore, the correct answer is **Option 4**.
