Detailed explanation-1: -Boveri observed that the spindle fibers radiate from structures at each pole that we now recognize as centrosomes, and he also noted that each centrosome contains two small, rodlike bodies, which are now known as centrioles.

Detailed explanation-2: -Spindle fibers are responsible for the separation of chromosomes during cell division. They form a part of the spindle apparatus that takes part during mitosis and meiosis to check that each daughter cell receives the correct chromosomes number.

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: -What is the role of a centriole in a cell? The centriole is concerned with the cell division. They help in the formation of spindle fibres that separate the chromosomes during the cell cycle.

Detailed explanation-5: -The segregation of the replicated chromosomes is brought about by a complex cytoskeletal machine with many moving parts-the mitotic spindle. It is constructed from microtubules and their associated proteins, which both pull the daughter chromosomes toward the poles of the spindle and move the poles apart.
