Sporogony is performed in mosquito because

Options

A. sporogony requires less (lower) ternperature.
B. human blood has become over crowded.
C. human blood kills Plasmodium gametes.
D. of unknown reasons

Answer

**Step-by-Step Solution:**

1. **Understanding Sporogony**: Sporogony is a process of asexual reproduction that occurs in certain protozoans, particularly in the life cycle of Plasmodium, the causative agent of malaria. This process leads to the formation of sporozoites, which are the infectious form of the parasite.

2. **Identifying the Host**: In the life cycle of Plasmodium, there are two main hosts: the mosquito (Anopheles species) and humans. The mosquito serves as the vector for the transmission of malaria.

3. **Temperature Requirements**: Sporogony requires specific environmental conditions to occur effectively. The optimal temperature for the development of sporozoites is between 16 to 30 degrees Celsius.

4. **Comparing Host Temperatures**: The body temperature of humans is approximately 37 degrees Celsius, which is higher than the optimal range for sporogony. This higher temperature is not conducive for the development of Plasmodium gametes into sporozoites.

5. **Conclusion**: Since the mosquito provides the suitable lower temperature range required for sporogony, this process occurs in mosquitoes rather than in humans. Therefore, the correct answer to the question is that sporogony is performed in mosquitoes because it requires lower temperatures.

**Final Answer**: Sporogony is performed in mosquitoes because it requires lower temperatures (16 to 30 degrees Celsius) that are suitable for the development of sporozoites.
