Sporozoans have locomotory organs

Options

A. Pseudopodia
B. Cilia
C. Flagella
D. None of the above.

Answer

### Step-by-Step Solution:

1. **Understanding Sporozoans**:
- Sporozoans are a group of protozoans that are characterized by their parasitic lifestyle. They belong to the kingdom Protista and are classified under the phylum Apicomplexa.

2. **Classification of Protozoans**:
- Protozoans are divided into four main groups based on their locomotory structures:
- **Ciliates**: These organisms use cilia for movement (e.g., Paramecium).
- **Flagellates**: These organisms use flagella for movement (e.g., Euglena).
- **Sarcodina**: These organisms use pseudopodia (false legs) for movement (e.g., Amoeba).
- **Sporozoa**: This group includes sporozoans, which do not have any specialized locomotory organs.

3. **Locomotory Organs in Sporozoans**:
- Unlike the other groups, sporozoans do not possess any locomotory organs. They are primarily parasitic and rely on their hosts for movement and transmission.

4. **Evaluating the Options**:
- **Option 1: Pseudopodia**: This is associated with Sarcodina (e.g., Amoeba) and does not apply to sporozoans.
- **Option 2: Cilia**: This is associated with Ciliates (e.g., Paramecium) and does not apply to sporozoans.
- **Option 3: Flagella**: This is associated with Flagellates (e.g., Euglena) and does not apply to sporozoans.
- **Option 4: None of the above**: Since sporozoans do not have any locomotory organs, this is the correct answer.

5. **Conclusion**:
- The correct answer to the question "Sporozoans have locomotory organs" is **None of the above**.
