During cell division chromosome move towards different poles due to:-

Options

A. Centriole
B. Vacuole formation
C. Microtubules
D. Cytokinesis

Answer

**Step-by-Step Solution:**

1. **Understanding Cell Division**: During cell division, specifically during mitosis and meiosis, chromosomes are separated and moved to opposite poles of the cell.

2. **Identifying the Mechanism**: The movement of chromosomes is primarily facilitated by structures known as microtubules, which are part of the spindle apparatus.

3. **Evaluating Options**:
- **Option 1: Centriole**: While centrioles play a role in organizing the spindle fibers, they do not directly cause the movement of chromosomes. Therefore, this option is incorrect.
- **Option 2: Vacuole Formation**: Vacuoles are involved in storage and osmoregulation, not in the movement of chromosomes during cell division. Thus, this option is also incorrect.
- **Option 3: Microtubule**: This is the correct answer. Microtubules extend from the centrosomes and attach to the chromosomes at their kinetochores, pulling them towards opposite poles during cell division.
- **Option 4: Cytokinesis**: Cytokinesis refers to the division of the cytoplasm after the chromosomes have been separated, and does not relate to the movement of chromosomes. Therefore, this option is incorrect.

4. **Conclusion**: The correct answer is that chromosomes move towards different poles during cell division due to microtubules.

**Final Answer**: Microtubules.
