The centromere is a part of a chromosome that links the sister chromatids or dyads. The spindle fibers attach to it during mitosis.

Centrosome is the organelle where all the cell microtubules get organized.They occur only in animal cells.


Also, centrosomes regulate the cell division cycle.

On the other hand, a centriole is a small set of microtubules arranged in a specific way. There are nine groups of microtubules. The centrioles are found in pairs and move towards the poles of the nucleus during the cell division.
