Detailed explanation-1: -And those mitotic spindles go and attach to each of the chromosomes and pull the chromosomes to opposite ends of the cell to allow cytokinesis, then, to occur. So the centrioles are critical to allow the mitotic spindle to form, which is critical to allow cytokinesis.

Detailed explanation-2: -Spindle fibers are assembled by microtubule-organizing center called centrosomes located at the ends of the spindle. In animal cells, centrosomes contain a pair of organelles called centrioles that help organize the spindle.

Detailed explanation-3: -Centrioles are found as single structures in cilia and flagella in animal cells and some lower plant cells. Centrioles are constructed of microtubules. In animal cells centrioles organise the pericentriolar material to produce microtubules including mitotic spindle fibres.

Detailed explanation-4: -Centrioles are responsible for organizing the spindle fibers in the mitotic spindle apparatus and are thought to participate in the completion of cytokinesis during the process of cell division.
