Chloragogen cells of earthworms are analogous to vertebrate

Options

A. Lungs
B. Liver
C. Gut
D. kidneys

Answer

**Step-by-Step Solution:**

1. **Understanding Chloragogen Cells**: Chloragogen cells are specialized cells found in earthworms. They are responsible for storing glycogen and neutralizing toxins. They also contain coelomic fluid.

2. **Identifying the Function of Chloragogen Cells**: The primary functions of chloragogen cells include the storage of glycogen and detoxification, similar to certain functions in vertebrates.

3. **Recognizing the Importance of Glycogen**: Glycogen is a form of stored glucose and is crucial for energy storage in both earthworms and vertebrates.

4. **Comparing to Vertebrate Anatomy**: In vertebrates, glycogen is primarily stored in the liver. This is a key point of comparison between chloragogen cells in earthworms and a specific organ in vertebrates.

5. **Conclusion**: Based on the functions and the role of glycogen storage, chloragogen cells in earthworms are analogous to the liver in vertebrates.

6. **Final Answer**: Therefore, the correct answer is that chloragogen cells of earthworms are analogous to the liver of vertebrates.
