Chlorella, Chlamydomonas, Amoeba, Paramaoecium are kept under this kingdom by Whittaker

Options

A. Plantae
B. Animalia
C. Protista
D. 1 and 2

Answer

To answer the question about which kingdom Chlorella, Chlamydomonas, Amoeba, and Paramecium are classified under by Whittaker, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organisms**:
- Chlorella: A unicellular green alga.
- Chlamydomonas: A unicellular green alga that can photosynthesize.
- Amoeba: A unicellular organism that is heterotrophic and moves using pseudopodia.
- Paramecium: A unicellular organism that is also heterotrophic and covered in cilia.

2. **Understand the Classification System**:
- Whittaker proposed a five-kingdom classification system which includes:
- Monera (prokaryotes)
- Protista (unicellular eukaryotes)
- Fungi (multicellular eukaryotes, mostly decomposers)
- Plantae (multicellular eukaryotes, photosynthetic)
- Animalia (multicellular eukaryotes, heterotrophic)

3. **Analyze the Characteristics of Each Kingdom**:
- **Plantae**: Multicellular, photosynthetic organisms.
- **Animalia**: Multicellular, heterotrophic organisms.
- **Protista**: Mostly unicellular eukaryotes, which can be autotrophic (like algae) or heterotrophic (like protozoa).

4. **Classify the Given Organisms**:
- All four organisms (Chlorella, Chlamydomonas, Amoeba, and Paramecium) are unicellular eukaryotes.
- Chlorella and Chlamydomonas are autotrophic (can photosynthesize), while Amoeba and Paramecium are heterotrophic.

5. **Conclusion**:
- Since all these organisms are unicellular eukaryotes, they fall under the kingdom **Protista** according to Whittaker's classification.

### Final Answer:
The correct kingdom for Chlorella, Chlamydomonas, Amoeba, and Paramecium as classified by Whittaker is **Protista**.
