Which group of animals belongs to class sporozoa

Options

A. Plasmodium & Monocystis
B. Entamoeba & Paramoecium
C. Euglena & Noctiluca
D. Plasmodium & Vorticella

Answer

To determine which group of animals belongs to the class Sporozoa, we can analyze the given options step by step.

### Step-by-Step Solution:

1. **Understanding Class Sporozoa**:
- The class Sporozoa consists of a group of protozoan parasites that are characterized by their spore-forming stage in their life cycle. They are primarily known for being intracellular parasites.

2. **Analyzing the Options**:
- **Option 1: Plasmodium and Monocelstis**:
- Plasmodium is a well-known genus of parasitic protozoa that causes malaria in humans. It belongs to the class Sporozoa.
- Monocelstis is also a genus of protozoa that falls under the same category. Therefore, this option is correct.

- **Option 2: Antamoeba and Paramecium**:
- Antamoeba (likely referring to Entamoeba) is a genus of amoeboid protozoa that belongs to the class Lobosia.
- Paramecium is a ciliate protozoan and does not belong to Sporozoa. Hence, this option is incorrect.

- **Option 3: Euglena and Noctiluca**:
- Euglena is a flagellate that is part of the group Euglenozoa, and Noctiluca is a dinoflagellate. Neither belongs to Sporozoa, making this option incorrect.

- **Option 4: Plasmodium and Vorticella**:
- As previously mentioned, Plasmodium belongs to Sporozoa, but Vorticella is a ciliate and belongs to the class Oligohymenophora. Therefore, this option is also incorrect.

3. **Conclusion**:
- The only correct option that includes animals belonging to the class Sporozoa is **Option 1: Plasmodium and Monocelstis**.

### Final Answer:
The group of animals that belongs to class Sporozoa is **Plasmodium and Monocelstis**.
