Detailed explanation-1: -The centrosome is the sole organelle that aids in cell division in both plant and other cells as well as animal cells.

Detailed explanation-2: -Centrioles are small organelles found only in eukaryotic cells that help ensure the new cells that form after cell division each contain a complete set of chromosomes. As the centrioles move apart, a spindle starts to form between them. The blue spindle, shown in Figure 7.3. 4, consists of fibers made of microtubules.

Detailed explanation-3: -And when the chromosomes are condensing to undergo mitosis, the centrioles form the areas that mitotic spindle forms from. 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.

Detailed explanation-4: -Spindle fibers form a protein structure that divides the genetic material in a cell. The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division: mitosis and meiosis.

Detailed explanation-5: -“Centriole is an organelle, cylindrical in shape, that is composed of a protein called tubulin.”
