Exflagellation in Plasmodium occurs in

Options

A. Merozoites
B. Megagametocytes
C. Microgametocytes
D. Metacryptmerozoites.

Answer

**Step-by-Step Solution:**

1. **Understanding Plasmodium**: Plasmodium is a genus of unicellular parasites known for causing malaria. The most common species is Plasmodium vivax.

2. **Life Cycle of Plasmodium**: The life cycle of Plasmodium involves two hosts: humans and female Anopheles mosquitoes. The infection begins when a female Anopheles mosquito bites a human and injects sporozoites into the bloodstream.

3. **Infection Process**: After entering the human body, sporozoites first travel to the liver, where they multiply. Following this, they enter red blood cells (RBCs) and undergo a process called multiple fission, resulting in the formation of merozoites.

4. **Formation of Gametocytes**: The merozoites can differentiate into two types of gametocytes: microgametocytes (male) and macrogametocytes (female).

5. **Exflagellation Process**: Exflagellation is a process that occurs in the microgametocyte. During this process, the microgametocyte undergoes division and forms elongated structures, which represent the male gametes.

6. **Fertilization**: The male gametes then enter the female gamete through a structure called the cone of reception, leading to the formation of a zygote.

7. **Conclusion**: Therefore, exflagellation in Plasmodium occurs specifically in the microgametocyte.

**Final Answer**: Exflagellation in Plasmodium occurs in the microgametocyte.
