Cells which lose their nucleus during differentiation are

Options

A. Nerve cells
B. Muscle cells
C. Erthrocytes
D. Leucocytes

Answer

**Step-by-Step Solution:**

1. **Understanding Cell Differentiation**: Cell differentiation is the process by which a less specialized cell becomes a more specialized cell type. During this process, certain cells may lose their nucleus as they mature.

2. **Analyzing the Options**:
- **A. Nerve Cells**: Nerve cells (neurons) do not lose their nucleus during differentiation. They retain their nucleus to support their functions in transmitting signals.
- **B. Muscle Cells**: Muscle cells (myocytes) also retain their nucleus. While they may have multiple nuclei in some types (like skeletal muscle), they do not lose them during differentiation.
- **C. Erythrocytes**: Erythrocytes, or red blood cells (RBCs), are unique in that they lose their nucleus during differentiation. This allows more space for hemoglobin, which is essential for oxygen transport.
- **D. Leukocytes**: Leukocytes (white blood cells) retain their nucleus as they play a crucial role in the immune response.

3. **Conclusion**: Based on the analysis, the only cells that lose their nucleus during differentiation are erythrocytes.

4. **Final Answer**: The cells which lose their nucleus during differentiation are called **C. Erythrocytes**.
