Chitin is component of cell wall of

Options

A. 1)Bacteria
B. 2)Fungi
C. 3)Algae
D. 4)Angiosperms

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the organism whose cell wall is composed of chitin.

2. **Identifying the Options**: The options provided are:
- A) Bacteria
- B) Fungi
- C) Algae
- D) Angiosperms (flowering plants)

3. **Analyzing Each Option**:
- **Option A: Bacteria**: The cell wall of bacteria is primarily made up of peptidoglycan, not chitin. Therefore, this option is incorrect.
- **Option B: Fungi**: The cell wall of fungi is composed of chitin, which is a key characteristic of this group. Thus, this option is correct.
- **Option C: Algae**: Algae typically have cell walls made of cellulose, not chitin. Therefore, this option is incorrect.
- **Option D: Angiosperms**: Angiosperms (flowering plants) also have cell walls made of cellulose, similar to algae. Thus, this option is incorrect.

4. **Conclusion**: Based on the analysis, the correct answer is **Option B: Fungi**, as it is the only group listed that has chitin as a component of its cell wall.

### Final Answer:
Chitin is a component of the cell wall of **Fungi**.
