Identify the organism that can prepare its own food through the process of photosynthesis

Options

A. Euglena
B. Paramecium
C. Amoeba
D. Vibrio

Answer

**Step-by-Step Solution:**

1. **Understanding Photosynthesis**: Photosynthesis is the process by which certain organisms convert light energy, usually from the sun, into chemical energy in the form of glucose. This process primarily occurs in plants, algae, and some bacteria.

2. **Identifying the Organisms**: The question provides four options: Euglena, Paramecium, Amoeba, and Vibrio. We need to determine which of these can perform photosynthesis.

3. **Analyzing Euglena**:
- Euglena is a unicellular organism, meaning it consists of a single cell.
- It possesses characteristics of both plants and animals. This duality allows it to perform photosynthesis due to the presence of chloroplasts, which are the organelles responsible for photosynthesis in plants.

4. **Examining Other Options**:
- **Paramecium**: This is a unicellular organism that is primarily heterotrophic, meaning it cannot perform photosynthesis.
- **Amoeba**: Similar to Paramecium, Amoeba is also a heterotrophic organism and does not have the capability to perform photosynthesis.
- **Vibrio**: This is a genus of bacteria that are also heterotrophic and do not perform photosynthesis.

5. **Conclusion**: Based on the analysis, Euglena is the only organism among the options that can prepare its own food through the process of photosynthesis.

**Final Answer**: The organism that can prepare its own food through the process of photosynthesis is **Euglena**.
