Chloragogen cells are present in

Options

A. Body wall of earthworm
B. Blood of earthworm
C. Coelomic fluid of earthworm
D. Blood of cockroach

Answer

**Step-by-Step Solution:**

1. **Understanding Chloragogen Cells**: Chloragogen cells are specialized cells found in certain invertebrates, particularly in earthworms.

2. **Identifying the Location**: The question asks where these cells are present. The options provided are:
- Body wall of earthworm
- Blood of earthworm
- Coelomic fluid of earthworm
- Blood of cockroach

3. **Analyzing Each Option**:
- **Body wall of earthworm**: Chloragogen cells are not primarily found in the body wall.
- **Blood of earthworm**: While earthworm blood contains many cells, Chloragogen cells are not specifically located here.
- **Coelomic fluid of earthworm**: This is the correct location for Chloragogen cells. They are found in the coelomic fluid and function similarly to the liver in vertebrates.
- **Blood of cockroach**: Chloragogen cells are not found in cockroaches.

4. **Functions of Chloragogen Cells**: These cells are involved in the storage of glycogen and detoxification, similar to the liver in vertebrates. They also help in excretion and are characterized by their yellowish color due to the presence of yellow granules.

5. **Conclusion**: Based on the analysis, the correct answer is that Chloragogen cells are present in the coelomic fluid of the earthworm.

**Final Answer**: Chloragogen cells are present in the coelomic fluid of the earthworm.
