(a) Three different stages of mitosis visible in the image are:
- Prophase/Prometaphase: Cells with condensed chromosomes are visible.
- Metaphase: Cells with chromosomes aligned at the metaphase plate are present.
- Anaphase: Cells with sister chromatids separating and moving towards opposite poles are visible.
(b) The spindle fibres play a crucial role in mitosis by attaching to the centromeres of the chromosomes. They then pull the sister chromatids apart during anaphase, ensuring that each daughter cell receives a complete set of chromosomes. The spindle fibres also help to move the chromosomes to the poles of the cell.
