During life cycle of plasmodium, fertilization and development takes place in the mosquito' s

Options

A. Blood
B. RBC' s
C. stomach
D. Liver

Answer

**Step-by-Step Solution:**

1. **Understanding the Life Cycle of Plasmodium**: Plasmodium is a parasite that causes malaria. Its life cycle involves two hosts: humans and female Anopheles mosquitoes.

2. **Infection Process**: The infection begins when an infected female Anopheles mosquito bites a human. During this bite, the mosquito injects the Plasmodium parasite in the form of sporozoites into the human bloodstream.

3. **Sporozoite Journey**: Once in the bloodstream, the sporozoites travel to the liver, where they invade liver cells.

4. **Asexual Multiplication**: Inside the liver, the sporozoites undergo asexual reproduction, multiplying rapidly. This process can take about 7 to 10 days before symptoms of malaria start to appear in the human host.

5. **Sexual Reproduction in Mosquito**: While the asexual phase occurs in humans, the sexual phase of Plasmodium takes place in the mosquito. After the mosquito bites an infected human, it ingests the gametocytes (the sexual forms of the parasite) along with the blood.

6. **Fertilization and Development**: Inside the mosquito's stomach, fertilization occurs between the male and female gametes of the Plasmodium. This leads to the development of zygotes and eventually sporozoites, which migrate to the mosquito's salivary glands, ready to infect another human when the mosquito bites again.

7. **Conclusion**: Therefore, the fertilization and development of Plasmodium occur in the stomach of the mosquito.

**Final Answer**: During the life cycle of Plasmodium, fertilization and development take place in the mosquito's stomach.
