Exflagellation in life cycle of Plasmodium occurs in

Options

A. Human R.B.C.
B. Liver cells of human
C. Gut of mosquito
D. Haemocoelom of mosquito

Answer

To answer the question regarding where exflagellation occurs in the life cycle of Plasmodium, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Exflagellation**:
- Exflagellation refers to the process where male gametes of Plasmodium undergo a transformation that allows them to develop flagella-like structures. This process is crucial for the mobility of the male gametes.

2. **Identifying the Life Cycle of Plasmodium**:
- Plasmodium has a complex life cycle that involves both a mosquito (the vector) and a human host. The life cycle includes stages such as sporozoites, merozoites, and gametocytes.

3. **Locating the Site of Exflagellation**:
- Exflagellation specifically occurs in the gut of the female Anopheles mosquito. This is where the male gametes are formed and undergo exflagellation to become motile.

4. **Transmission to the Salivary Gland**:
- After exflagellation, the male gametes fertilize the female gametes to form zygotes, which develop into ookinetes. These ookinetes then penetrate the mosquito's gut wall and develop into oocysts, eventually leading to the formation of sporozoites that migrate to the salivary glands.

5. **Conclusion**:
- Therefore, the correct answer to the question is that exflagellation in the life cycle of Plasmodium occurs in the gut of the mosquito.

### Final Answer:
Exflagellation in the life cycle of Plasmodium occurs in the gut of the mosquito.
