Which of the following are analogous to vertebrate liver cells ?

Options

A. Chromophil cells
B. Chlorogogen cells
C. Calciferous glands cells
D. Albumen cells

Explanation

To determine which of the given options are analogous to vertebrate liver cells, we need to analyze the functions of each cell type and compare them to the functions of liver cells in vertebrates.

### Step-by-Step Solution:

1. **Understand the Function of Vertebrate Liver Cells:**
- The liver in vertebrates is responsible for several critical functions, including the metabolism of nutrients (like glycogen), detoxification of harmful substances, and secretion of bile.

2. **Analyze the Given Options:**
- **Chromophile Cells:** These cells are not related to liver functions and are primarily involved in the secretion of hormones in certain organisms. Therefore, they are not analogous to liver cells.
- **Chlorogogin Cells:** These cells are found in earthworms and are involved in the digestion of glycogen and the removal of toxins. This function is similar to that of liver cells, making them a potential candidate.
- **Calciferous Gland Cells:** These cells help in maintaining the pH of food and are not directly involved in metabolic functions or detoxification. Thus, they are not analogous to liver cells.
- **Albumin Cells:** These cells are responsible for maintaining osmotic balance in the blood but do not perform functions similar to those of liver cells, such as metabolism or detoxification.

3. **Identify the Correct Answer:**
- Among the options, **Chlorogogin Cells** are the only ones that perform functions similar to those of liver cells in vertebrates, such as glycogen metabolism and detoxification.

### Conclusion:
The correct answer is **Chlorogogin Cells** as they are analogous to vertebrate liver cells.
