Identify unicellular eukaryotic group of organisms.

Options

A. Monera
B. Protista
C. Fungi
D. None of these

Answer

To identify the unicellular eukaryotic group of organisms, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Classification of Organisms**: Organisms are classified into two main categories based on their cellular structure: prokaryotes and eukaryotes. Prokaryotes are single-celled organisms without a nucleus, while eukaryotes have a defined nucleus and can be unicellular or multicellular.

2. **Identify the Groups Mentioned**: The question provides four groups of organisms: Monera, Protista, Fungi, and Eukaryota. We need to determine which of these groups contains unicellular eukaryotic organisms.

3. **Analyze Each Group**:
- **Monera**: This group includes prokaryotic organisms, primarily bacteria. Therefore, it does not contain unicellular eukaryotes.
- **Protista**: This group is known for containing unicellular eukaryotic organisms. Examples include Paramecium and Amoeba, which are both unicellular and have a nucleus.
- **Fungi**: This group generally consists of multicellular eukaryotic organisms, such as molds and mushrooms. Thus, it does not represent unicellular eukaryotes.
- **Eukaryota**: This term refers to all eukaryotic organisms, which include both unicellular and multicellular forms. However, it is not a specific group that solely identifies unicellular eukaryotes.

4. **Conclusion**: The unicellular eukaryotic group of organisms is **Protista**. This group includes various organisms that are primarily unicellular and possess a nucleus.

### Final Answer:
The unicellular eukaryotic group of organisms is **Protista**.
