In which the following column I is incorrectly matched with column II ?

Options

A.
B.
C.
D.

Answer

To solve the question regarding the incorrect matching of organisms' cell walls with their compositions, we will analyze each option step by step.

### Step 1: Analyze Option 1
- **Organism**: Plants
- **Cell Wall Composition**: Cellulose and Hemicellulose
- **Evaluation**: This is a correct match. The cell wall of plants is indeed composed of cellulose and hemicellulose.

**Hint**: Recall that plant cell walls are primarily made of cellulose, a polysaccharide.

### Step 2: Analyze Option 2
- **Organism**: Algae (LGA)
- **Cell Wall Composition**: Cellulose and Galactans
- **Evaluation**: This is also a correct match. Algae, particularly certain types, have cell walls that contain cellulose and galactans.

**Hint**: Remember that some algae have unique components in their cell walls, including galactans.

### Step 3: Analyze Option 3
- **Organism**: Bacteria
- **Cell Wall Composition**: Cellulose and Galactans
- **Evaluation**: This is an incorrect match. The cell wall of bacteria is primarily made of peptidoglycan, not cellulose and galactans.

**Hint**: Bacterial cell walls are distinct from plant and algal cell walls; think of peptidoglycan as the key component.

### Step 4: Analyze Option 4
- **Organism**: Fungi
- **Cell Wall Composition**: Chitin
- **Evaluation**: This is a correct match. The cell wall of fungi is composed of chitin.

**Hint**: Chitin is a characteristic component of fungal cell walls, different from cellulose.

### Conclusion
After analyzing all options, we find that the incorrect match is in **Option 3**, where the cell wall composition of bacteria is incorrectly stated as cellulose and galactans instead of peptidoglycan.

**Final Answer**: Option 3 is incorrectly matched.
