Bacteria differ from other filamentous fungal groups in one of the following feature?

Options

A. Cell wall of bacteria is cellulose
B. Heterotrophic nutrition in fungi
C. Binary fission in bacteria
D. presence of chlorophyll

Explanation

To solve the question regarding how bacteria differ from other filamentous fungal groups, we will analyze the options provided and compare the characteristics of bacteria and fungi.

### Step-by-Step Solution:

1. **Understanding the Cell Wall Composition**:
- Bacteria have a cell wall made up of **peptidoglycan**.
- Fungi have a cell wall made up of **chitin** (not cellulose, which is a common misconception).
- **Conclusion**: The statement that bacteria have a cell wall of cellulose is incorrect.

2. **Nutritional Modes**:
- Bacteria can be **heterotrophic** (obtaining food from organic substances) or **autotrophic** (producing their own food).
- Fungi are primarily **saprophytic**, meaning they obtain nutrients by decomposing dead organic matter.
- **Conclusion**: The statement regarding heterotrophic nutrition in fungi is misleading since fungi primarily engage in saprophytic nutrition.

3. **Reproductive Methods**:
- Bacteria reproduce mainly through **binary fission**, which is a form of asexual reproduction.
- Fungi can reproduce through various methods, including **fragmentation** and **budding**.
- **Conclusion**: The statement about binary fission being a method of reproduction in bacteria is correct, and this is a significant difference from fungi.

4. **Presence of Chlorophyll**:
- Neither bacteria nor fungi typically possess chlorophyll, as they do not perform photosynthesis in the same way that plants do.
- **Conclusion**: The statement about the presence of chlorophyll in bacteria or fungi is incorrect.

### Final Answer:
The correct answer to the question is that bacteria differ from filamentous fungi in their method of reproduction, specifically through **binary fission**.
