Trophozoites of Plasmodium occur in

Options

A. Liver cells
B. Spleen
C. Lymph channels
D. Red blood corpuscles.

Answer

To answer the question "Trophozoites of Plasmodium occur in," we will analyze the options provided and understand the biology of Plasmodium.

### Step-by-Step Solution:

1. **Understanding Trophozoites**:
- Trophozoites are the active feeding stage of the Plasmodium parasite. They are responsible for the disease malaria.

2. **Identifying the Host Cells**:
- Plasmodium is a parasitic organism that infects humans and other hosts. The trophozoites feed on the host's cells.

3. **Analyzing the Options**:
- **Option 1: Liver Cells**: While Plasmodium does affect the liver during its life cycle, the trophozoite stage does not occur here. The liver is primarily involved in the early stages of infection.
- **Option 2: Spleen**: The spleen acts as a graveyard for red blood cells (RBCs) but is not where trophozoites reside.
- **Option 3: Lymph Channel**: Lymph channels are part of the immune system and are not directly involved in the life cycle of Plasmodium trophozoites.
- **Option 4: Red Blood Corpuscles**: This is the correct answer. Trophozoites of Plasmodium occur in red blood cells, where they feed and multiply, leading to the destruction of these cells.

4. **Conclusion**:
- The trophozoites of Plasmodium occur in red blood corpuscles (RBCs). This is where they actively feed and cause damage, leading to the symptoms of malaria.

### Final Answer:
- The trophozoites of Plasmodium occur in **red blood corpuscles**.
