In which of the following cell centriole is absent –

Options

A. Epithelial cell
B. Gland cell
C. Liver cells
D. Nerve cell

Answer

To determine in which type of cell the centriole is absent, we will analyze each of the provided options step by step.

### Step-by-Step Solution:

1. **Identify the Options**: The options given are:
- Epithelial cells
- Gland cells
- Liver cells
- Nerve cells

2. **Analyze Epithelial Cells**:
- Epithelial cells are known to have centrioles. They play a role in cell division and are involved in the formation of tissues.
- **Conclusion**: Epithelial cells have centrioles.

3. **Analyze Gland Cells**:
- Gland cells, like epithelial cells, also possess centrioles. They are involved in secretion and can undergo cell division.
- **Conclusion**: Gland cells have centrioles.

4. **Analyze Liver Cells**:
- Liver cells (hepatocytes) also contain centrioles. They are capable of cell division and regeneration.
- **Conclusion**: Liver cells have centrioles.

5. **Analyze Nerve Cells**:
- Nerve cells (neurons) are unique in that they do not have centrioles. They generally do not divide or undergo mitosis, which is why they lack centrioles.
- **Conclusion**: Nerve cells do not have centrioles.

6. **Final Answer**:
- Based on the analysis, the correct answer to the question "In which of the following cell centriole is absent?" is **nerve cells**.
