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

Options

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

Answer

To determine which of the following organism and its cell wall degrading enzyme pairs is incorrectly matched, we will analyze each option step by step.

### Step-by-Step Solution

1. **Identify the Organism and its Cell Wall Degrading Enzyme:**
- We need to look at the options provided and identify the organism and the enzyme associated with it.

2. **Analyze the First Option:**
- **Organism:** Plants
- **Enzyme:** Cellulase
- **Analysis:** Plant cell walls are primarily made of cellulose. The enzyme cellulase is responsible for breaking down cellulose. This match is correct.

3. **Analyze the Second Option:**
- **Organism:** Algae
- **Enzyme:** Methylase
- **Analysis:** Algal cell walls are also composed of cellulose, similar to plant cell walls. The enzyme that breaks down cellulose is cellulase, not methylase. Methylase adds a methyl group to adenine in RNA, which is unrelated to cell wall degradation. This match is incorrect.

4. **Analyze the Third Option:**
- **Organism:** Fungi
- **Enzyme:** Chitinase
- **Analysis:** Fungal cell walls are primarily made of chitin. The enzyme chitinase is responsible for breaking down chitin. This match is correct.

5. **Analyze the Fourth Option:**
- **Organism:** Bacteria
- **Enzyme:** Lysozyme
- **Analysis:** Bacterial cell walls are made of peptidoglycan. Lysozyme is an enzyme that breaks down peptidoglycan. This match is correct.

6. **Conclusion:**
- The only incorrect match is the second option where algae are matched with methylase. The correct enzyme for degrading algal cell walls, which contain cellulose, should be cellulase.

### Final Answer:
The incorrect match is: **Algae - Methylase.**
