Given organisms belong to how many kingdoms according to Whittaker system? Chlorella, Clostridium, Euglena,Chlamydomonas, Cycas

Options

A. One
B. Two
C. Four
D. Three

Answer

To determine how many kingdoms the given organisms belong to according to the Whittaker system, we will classify each organism based on the five kingdoms proposed by R.H. Whittaker. The five kingdoms are Monera, Protista, Fungi, Plantae, and Animalia.

1. **Identify the Organisms**:
- Chlorella
- Clostridium
- Euglena
- Chlamydomonas
- Cycas

2. **Classify Each Organism**:
- **Chlorella**: This is a type of green algae, which belongs to the **Plantae** kingdom.
- **Clostridium**: This is a genus of bacteria, which belongs to the **Monera** kingdom.
- **Euglena**: This organism is a protist that has characteristics of both plants and animals, so it belongs to the **Protista** kingdom.
- **Chlamydomonas**: This is also a type of green algae, similar to Chlorella, and belongs to the **Plantae** kingdom.
- **Cycas**: This is a genus of gymnosperms (seed-producing plants), which also belongs to the **Plantae** kingdom.

3. **Count the Distinct Kingdoms**:
- From the classifications:
- Plantae: Chlorella, Chlamydomonas, Cycas
- Monera: Clostridium
- Protista: Euglena
- The distinct kingdoms represented are **Monera**, **Protista**, and **Plantae**.

4. **Conclusion**:
- Therefore, the given organisms belong to a total of **three kingdoms** according to the Whittaker system.

**Final Answer**: The organisms belong to **three kingdoms**: Monera, Protista, and Plantae.
