Centrioles are minute submicroscopic sub-cylindrical structures which usually occur in pairs, inside a specialised cytoplasm called centrosphere or kinoplasm. The whole complex is called as centrosome, having two centrioles lying at right angles to each other.
They occur in cytoplasm of animal cells. Centrosomes give rise to spindle fibres and are responsible for movement of chromosomes during cell division.
