Centrioles are a very important organelle in animal cells. The  function of the centrioles is to aide in cell division. When a cell divides whether it is by Mitosis or Meiosis the centrioles play a role in producing thin fibers called “spindle fibers” which attach to the centromere of the chromosomes and pull them to opposite sides of the cell. Centrioles are found in pairs in the cell and during cell division one centriole pair will go to one pole of the cell and the other centriole pair will go to the opposite pole. When a cell is not dividing, however, centrioles cannot be seen in the cell. Centrioles are made up of structures called “microtubules” which are very thin protein tubes.
