centrosome

Microtubule organizing center

A centrosome is a structure in animal cells that organizes the microtubules—the internal scaffolding that gives cells their shape and enables movement.

During cell division, the centrosome duplicates and the two copies move to opposite ends of the cell, directing the formation of the spindle apparatus that pulls chromosomes apart.

The centrosome serves as the cell's main microtubule organizing center.
