Function of centrosome is :–

Options

A. Initiation of cell div
B. Inhibition of cell div
C. Termination of cell div
D. Cytokinesis

Answer

**Step-by-Step Solution:**

1. **Understanding the Centrosome**: The centrosome is an organelle found in animal cells that plays a crucial role in cell division. It consists of a pair of centrioles and is located near the nucleus.

2. **Role in Cell Division**: The primary function of the centrosome is to organize microtubules and form the mitotic spindle during cell division. This spindle is essential for the separation of chromosomes.

3. **Centrioles and Spindle Fibers**: The centrioles within the centrosome help in the formation of spindle fibers. These fibers attach to the chromosomes and pull them apart during mitosis, ensuring that each daughter cell receives the correct number of chromosomes.

4. **Evaluating Options**:
- **Option 1: Initiation of cell division** - This is correct as the centrosome is involved in the early stages of cell division by organizing the spindle apparatus.
- **Option 2: Inhibition of cell division** - This is incorrect. The centrosome does not inhibit cell division; rather, it facilitates it.
- **Option 3: Termination of cell division** - This is also incorrect. The centrosome does not play a role in terminating cell division.
- **Option 4: Cytokinesis** - While the centrosome is involved in cell division, cytokinesis specifically refers to the division of the cytoplasm, which is a separate process.

5. **Conclusion**: Based on the functions of the centrosome, the correct answer is that its function is the initiation of cell division.

**Final Answer**: The function of the centrosome is the initiation of cell division.
