Which of the following feature is common to bacteria , mosses and fungus ?

Options

A. Mode of nutrition
B. Presence of cell wall
C. Autotrophic
D. Body organization

Answer

To determine the common feature among bacteria, mosses, and fungi, we can analyze the options provided in the question step by step.

### Step 1: Analyze the Mode of Nutrition
- **Bacteria**: They can be autotrophic (able to produce their own food) or heterotrophic (relying on other organisms for food).
- **Mosses**: They are autotrophic as they perform photosynthesis.
- **Fungi**: They are primarily saprophytic, meaning they obtain nutrients by decomposing organic matter.

**Conclusion**: The mode of nutrition is not common among all three groups.

### Step 2: Examine the Presence of a Cell Wall
- **Bacteria**: They have a rigid cell wall made of peptidoglycan.
- **Mosses**: They have a cell wall made of cellulose.
- **Fungi**: They have a cell wall made of chitin.

**Conclusion**: All three groups possess a cell wall, though the composition varies, making this a common feature.

### Step 3: Consider Autotrophic Nature
- **Bacteria**: As mentioned, they can be either autotrophic or heterotrophic.
- **Mosses**: They are strictly autotrophic.
- **Fungi**: They are heterotrophic.

**Conclusion**: This feature is not common as the nutritional modes differ.

### Step 4: Analyze Body Organization
- **Bacteria**: They are prokaryotic and unicellular, lacking a true nucleus.
- **Mosses**: They are eukaryotic and multicellular.
- **Fungi**: They can be unicellular (like yeast) or multicellular (like mushrooms), but they are also eukaryotic.

**Conclusion**: The body organization differs significantly among these groups.

### Final Conclusion
The common feature among bacteria, mosses, and fungi is the **presence of a cell wall**. Therefore, the correct answer is the option that states "presence of the cell wall."
