Which of the following organisms possessses characteristics of a plant and an animal ?

Options

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

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for an organism that exhibits characteristics of both plants and animals. This means we need to identify an organism that has features typical of both kingdoms.

2. **Reviewing the Options**: The options provided are:
- Euglena
- Paramecium
- Bacteria
- Mycoplasma

3. **Analyzing Each Option**:
- **Euglena**: This organism is known to possess chlorophyll-a, which allows it to perform photosynthesis, a characteristic of plants. Additionally, in the absence of sunlight, Euglena can consume food like an animal. Therefore, it exhibits traits of both plants and animals.
- **Paramecium**: This is a ciliated protozoan that primarily feeds on bacteria and does not have plant-like characteristics.
- **Bacteria**: These are prokaryotic organisms that do not possess the characteristics of either plants or animals in the traditional sense.
- **Mycoplasma**: These are the smallest known living cells and are also prokaryotic, lacking plant or animal traits.

4. **Conclusion**: Based on the analysis, Euglena is the only organism that possesses characteristics of both plants (due to its ability to photosynthesize) and animals (as it can feed like an animal in the absence of light).

5. **Final Answer**: The correct answer is **Euglena**.
