Which organelle initiates cell division?

The centrosome is an organelle that plays a crucial role in initiating cell division. It contains a pair of centrioles, which serve as the nucleation sites for microtubule assembly. During cell division, the centrosomes move to opposite poles of the cell, and the microtubules they generate form the spindle apparatus that separates the chromosomes. The centromere is a region of DNA on the chromosome to which the microtubules attach, while the chromomere is a subunit of the chromosome.
