Unicellular animals are placed in the kingdom

Options

A. Animals
B. Protista
C. Monera
D. Metaphyta

Answer

**Step-by-Step Solution:**

1. **Identify the Kingdoms**: The question asks about the classification of unicellular animals. We need to consider the main biological kingdoms: Animalia, Protista, Monera, and Plantae.

2. **Analyze Each Kingdom**:
- **Kingdom Monera**: This kingdom includes unicellular prokaryotes, which are not classified as animals.
- **Kingdom Protista**: This kingdom consists of unicellular eukaryotes, which include protozoans that can be considered primitive relatives of animals.
- **Kingdom Fungi**: This kingdom is primarily made up of multicellular eukaryotes and does not include unicellular animals.
- **Kingdom Plantae**: This kingdom includes multicellular eukaryotic plants, not animals.

3. **Determine the Correct Kingdom**: Since unicellular animals (like protozoans) are classified as eukaryotes and are considered primitive relatives of animals, they fall under the kingdom Protista.

4. **Conclude**: Therefore, the correct answer to the question is that unicellular animals are placed in the kingdom **Protista**.

**Final Answer**: Unicellular animals are placed in the kingdom **Protista**.
