kingdom of unicellular eukaryotes is

Options

A. Monera
B. Protista
C. Fungi
D. Cyanobacteria

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the kingdom that includes unicellular eukaryotes.

2. **Identifying the Options**: The options provided include Monera, Protista, Fungi, and Cyanobacteria.

3. **Analyzing Monera**:
- Monera is a kingdom that consists of prokaryotic organisms.
- Prokaryotes are unicellular but lack a well-defined nucleus and organelles.
- Since the question specifically asks for unicellular eukaryotes, Monera is not the correct kingdom.

4. **Analyzing Protista**:
- Protista is the kingdom that includes unicellular eukaryotes.
- Eukaryotes have a well-defined nucleus and various organelles.
- Examples of organisms in this kingdom include protozoa and some algae, which are unicellular.
- Therefore, this option is likely the correct answer.

5. **Analyzing Fungi**:
- Fungi are primarily multicellular organisms, although there are unicellular forms like yeast.
- However, since the question specifically asks for the kingdom of unicellular eukaryotes, Fungi does not represent the entire group of unicellular eukaryotes.

6. **Analyzing Cyanobacteria**:
- Cyanobacteria are a type of bacteria that can perform photosynthesis.
- They are prokaryotic organisms and fall under the Monera kingdom.
- Thus, they do not fit the criteria of unicellular eukaryotes.

7. **Conclusion**: Based on the analysis, the kingdom that contains unicellular eukaryotes is **Protista**.

**Final Answer**: The kingdom of unicellular eukaryotes is **Protista**.
