Fungi differs from bacteria in

Options

A. Mode of nutrition
B. Having NAG in cell wall
C. Flagella structure
D. Reserve food material as glycogen

Answer

To answer the question "Fungi differs from bacteria in," we will analyze the differences between fungi and bacteria based on their characteristics. Here’s a step-by-step solution:

### Step 1: Understand the Mode of Nutrition
- **Fungi**: Fungi are primarily heterotrophic, meaning they obtain their food from other organic sources. They can be parasitic, symbiotic, or saprophytic.
- **Bacteria**: Bacteria can be autotrophic (producing their own food through photosynthesis or chemosynthesis) or heterotrophic (some are parasites or saprophytes).

**Conclusion**: There is some overlap in nutritional modes, so this option does not highlight a clear difference.

### Step 2: Analyze Cell Wall Composition
- **Fungi**: The cell wall of fungi is made of chitin, which contains N-acetylglucosamine.
- **Bacteria**: Bacterial cell walls are made of peptidoglycan, which includes N-acetylmuramic acid and N-acetylglucosamine.

**Conclusion**: Both fungi and bacteria contain N-acetylglucosamine, so this option does not show a distinct difference.

### Step 3: Examine Flagellar Structure
- **Fungi**: Fungi do not have flagella.
- **Bacteria**: Many motile bacteria possess flagella.

**Conclusion**: The absence of flagella in fungi compared to bacteria does not indicate a unique feature of fungi.

### Step 4: Identify Reserve Food Material
- **Fungi**: The reserve food material in fungi is glycogen.
- **Bacteria**: Bacteria store reserve food in the form of lipid globules, protein granules, or poly-beta-hydroxybutyrate (PBH granules).

**Conclusion**: This is a clear difference, as fungi store energy as glycogen while bacteria use various other forms.

### Final Answer
The correct answer is that fungi differ from bacteria in their reserve food material, which is glycogen in fungi and various forms in bacteria.
