Which one of the following organisms acts as connecting link in possessing characters of plants and animals ?

Options

A. Euglena
B. Bacteria
C. Mycoplasma
D. Paramecium

Answer

To determine which organism acts as a connecting link between plants and animals, we can analyze the characteristics of each option provided.

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for an organism that exhibits characteristics of both plants and animals.

2. **Analyze the Options**: We need to evaluate each option to see which one has traits of both kingdoms.

3. **Evaluate Euglena**:
- **Characteristics of Plants**: Euglena contains chloroplasts, which allow it to perform photosynthesis. This means it can produce its own food, similar to plants, indicating autotrophic nutrition.
- **Characteristics of Animals**: Euglena lacks a cell wall, which is a typical characteristic of plant cells. Instead, it has a flagellum that aids in movement and obtaining food, allowing it to exhibit heterotrophic nutrition (feeding on organic matter) when sunlight is not available.

4. **Evaluate Other Options**:
- **Bacteria**: These are prokaryotic organisms and do not possess characteristics of both plants and animals.
- **Mycoplasma**: Also a prokaryote, it lacks the features of both kingdoms.
- **Paramecium**: This is a unicellular organism that primarily exhibits animal-like characteristics and does not have plant-like features.

5. **Conclusion**: Based on the analysis, Euglena is the only organism that possesses characteristics of both plants (through photosynthesis) and animals (through motility and heterotrophic nutrition). Therefore, the correct answer is Euglena.

### Final Answer:
**Euglena** acts as a connecting link in possessing characters of both plants and animals.
