Motile elongate zygote of Plasmodium occurs in

Options

A. Human RBCs
B. Human liver
C. Gut of female Anopheles
D. Salivary glands of Anopheles

Answer

To solve the question about where the motile elongate zygote of Plasmodium occurs, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Plasmodium**:
- Plasmodium is a protozoan parasite responsible for malaria, which is transmitted to humans through the bite of infected female Anopheles mosquitoes.

2. **Identifying the Lifecycle**:
- The lifecycle of Plasmodium involves both human and mosquito hosts. In humans, the parasite undergoes asexual reproduction, while in the mosquito, it undergoes sexual reproduction.

3. **Examining the Options**:
- The question provides four options:
- Human RBC (Red Blood Cells)
- Human liver
- Gut of female Anopheles
- Salivary glands of Anopheles

4. **Analyzing Each Option**:
- **Human RBC**: This is incorrect because the zygote does not form in human blood cells; instead, the parasite undergoes asexual reproduction in RBCs.
- **Human Liver**: This is also incorrect as the liver is not the site for zygote formation; it is primarily involved in the asexual phase of the parasite.
- **Gut of Female Anopheles**: This is the correct option. When the mosquito feeds on an infected human, the male and female gametes are ingested and fuse in the gut to form the motile elongate zygote.
- **Salivary Glands of Anopheles**: This is incorrect as the salivary glands do not harbor the zygote; they are involved in the transmission of the parasite through saliva.

5. **Conclusion**:
- The motile elongate zygote of Plasmodium occurs in the gut of the female Anopheles mosquito.

### Final Answer:
The motile elongate zygote of Plasmodium occurs in the **gut of female Anopheles** mosquito.
