Which work together to move chromosome during cell division?

During cell division, particularly mitosis and meiOSis, the main structures that work together to move chromosomes are the spindle fibers and the centromeres. Spindle fibers, which are composed of microtubules, attach to the centromeres of the chromosomes and help align them at the cell's equatorial plane. As the cell divides, these fibers pull the sister chromatids apart toward opposite poles of the cell, ensuring that each daughter cell receives an identical set of chromosomes.
