Centrosomes are the centers for the proper organisation of microtubules that appear in prophase and then move to the polar ends of the cell.

Centromere is part of the chromosome where the DNA is wound tightly than the other DNA. It is used for counting chromosomes.

Centrioles are found near the centrosomes and functions in microtubule formation.

Kinetochore lies on the centrosomes of the chromosomes and is the point at which mitotic spindle connects.
