centriole
Cylindrical microtubule structure
A centriole is a cylindrical structure in animal cells that helps organize cell division.
Centrioles occur in pairs, forming the centrosome, which generates the spindle fibers that pull chromosomes apart during mitosis.
Plant cells and fungi typically lack centrioles, using other mechanisms to divide.
