Which of these combinations is correct about protozoans ?

Options

A. Entamoeba - Sporozoan , Paramecium - ciliated protozoan
B. Plasmodium - Sporozoan , Trypanosome - Ciliated protozoan
C. Paramecium - Ciliated protozoan, Trypanosome - Flagellated Protozoan
D. Entamoeba - Ciliated protozoan , Plasmodium - Flagellated protozoan

Answer

To solve the question about the correct combinations related to protozoans, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Protozoans**:
- Protozoans are unicellular eukaryotic organisms classified under the kingdom Protista. They can be motile or non-motile and can be classified based on their movement mechanisms: amoeboid (using pseudopodia), ciliated (using cilia), and flagellated (using flagella).

2. **Analyzing Option A**:
- **Entamoeba**: This is a genus of amoeboid protozoans that move using pseudopodia.
- **Sporozoans**: These are non-motile protozoans that are strictly parasitic.
- **Combination**: Since Entamoeba is motile (using pseudopodia) and sporozoans are non-motile, this combination is incorrect.

3. **Analyzing Option B**:
- **Paramecium**: This is a ciliated protozoan that moves using cilia.
- **Plasmodium**: This is a sporozoan that is non-motile and causes malaria.
- **Combination**: The first part (Paramecium - ciliated) is correct, but the second part (Trypanosome - ciliated) is incorrect because Trypanosome is a flagellated protozoan. Therefore, this combination is incorrect.

4. **Analyzing Option C**:
- **Paramecium**: Ciliated protozoan (correct).
- **Trypanosome**: Flagellated protozoan (correct).
- **Combination**: Both parts of this option are correct, making this the correct combination.

5. **Analyzing Option D**:
- **Entamoeba**: This is motile and uses pseudopodia, not cilia.
- **Plasmodium**: This is a non-motile sporozoan.
- **Combination**: The first part is incorrect (Entamoeba is not ciliated), and the second part is also incorrect (Plasmodium is not flagellated). Therefore, this option is incorrect.

### Conclusion:
The correct answer is **Option C**, which states that Paramecium is a ciliated protozoan and Trypanosome is a flagellated protozoan.
