Chloragogen cells are involved in

Options

A. Digestion
B. Excretion of water
C. Respiration
D. Fat storage

Answer

**Step-by-Step Solution:**

1. **Understanding Chloragogen Cells**: Chloragogen cells are specialized cells found in certain invertebrates, particularly in earthworms. They are star-shaped and are also referred to as Y cells or yellow cells due to their appearance.

2. **Function of Chloragogen Cells**: These cells have multiple functions, primarily related to metabolism and excretion. They play a role similar to that of the liver in vertebrates.

3. **Excretory Function**: Chloragogen cells are involved in the excretion of waste products from the coelomic fluid, which is the fluid within the body cavity of the earthworm.

4. **Storage of Glycogen**: One of the key functions of chloragogen cells is to store glycogen, which is a form of energy storage. They also help in neutralizing toxins that may be present in the body.

5. **Elimination of Incorrect Options**:
- **Digestion**: This process occurs primarily in the intestine, not in chloragogen cells.
- **Excretion of Water**: While they do have an excretory function, their primary role is not specifically the excretion of water.
- **Respiration**: Earthworms respire through their moist skin, not through chloragogen cells.

6. **Conclusion**: Based on the functions of chloragogen cells, the correct answer to the question is that they are involved in **fat storage**.
