The motile zygote after fertilization in Plasmodium is called

Options

A. a) oocyst
B. b) ookinete
C. c) gamont
D. d) trophozoites

Answer

To answer the question, "The motile zygote after fertilization in Plasmodium is called," we need to follow these steps:

### Step-by-Step Solution

1. **Understand the Organism**:
- Plasmodium is a genus of parasitic protozoa that causes malaria in humans. It is important to know that it has a complex life cycle involving both human hosts and female Anopheles mosquitoes.

2. **Identify the Life Cycle Stages**:
- In the life cycle of Plasmodium, fertilization occurs when male and female gametes combine to form a zygote.

3. **Define the Zygote**:
- The zygote formed after fertilization is motile, meaning it has the ability to move. This is a key characteristic that distinguishes it from other stages in the life cycle.

4. **Determine the Correct Terminology**:
- The motile zygote in Plasmodium is specifically referred to as "eukainate." This term is used to describe the motile zygote that can move within the environment, particularly in the gut of the female Anopheles mosquito.

5. **Eliminate Incorrect Options**:
- Other terms mentioned include oocyst, gamont, and trophozoite.
- Oocyst refers to a stage that develops after the eukainate.
- Gamont refers to the reproductive stage in the life cycle.
- Trophozoites are the feeding stage of the parasite.
- Thus, these terms do not describe the motile zygote.

6. **Conclusion**:
- Therefore, the correct answer to the question is "eukainate."

### Final Answer:
The motile zygote after fertilization in Plasmodium is called **eukainate**.
