In the five- kingdom classification , which kingdom occupies an intermediate position from a phylogenetic point of view ?

Options

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

Answer

To solve the question of which kingdom occupies an intermediate position from a phylogenetic point of view in the five-kingdom classification, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Five-Kingdom Classification**:
- The five-kingdom classification system was proposed by R.H. Whittaker and includes the kingdoms: Monera, Protista, Fungi, Plantae, and Animalia.

2. **Identifying the Characteristics of Each Kingdom**:
- **Monera**: This kingdom consists of prokaryotic organisms, primarily bacteria, which lack a true nucleus and membrane-bound organelles.
- **Protista**: This kingdom includes eukaryotic organisms, primarily single-celled organisms. They possess a true nucleus and membrane-bound organelles.
- **Fungi**: This kingdom consists of multicellular eukaryotic organisms that absorb nutrients from their environment.
- **Plantae**: This kingdom includes multicellular eukaryotic organisms that perform photosynthesis.
- **Animalia**: This kingdom consists of multicellular eukaryotic organisms that are heterotrophic and typically have complex organ systems.

3. **Determining the Intermediate Position**:
- To find the kingdom that occupies an intermediate position, we need to look for a kingdom that has characteristics of both prokaryotes and eukaryotes.
- Monera is entirely prokaryotic, while Plantae and Animalia are multicellular eukaryotes.
- Protista, on the other hand, consists of single-celled eukaryotes, which makes it a bridge between the prokaryotic Monera and the multicellular kingdoms (Plantae and Animalia).

4. **Conclusion**:
- Therefore, the kingdom that occupies an intermediate position from a phylogenetic point of view is **Protista**.

### Final Answer:
The kingdom that occupies an intermediate position from a phylogenetic point of view in the five-kingdom classification is **Protista**.
