centrioles
Cell division anchors
Centrioles are cylindrical structures found in animal cells that help organize cell division.
They occur in pairs near the nucleus, forming the centrosome, which generates the spindle fibers that pull chromosomes apart during mitosis.
Most plant cells and fungi lack centrioles, using other mechanisms to divide.
