The Centrosome
Captions available
The idea
The centrosome is a microtubule-organizing structure near an animal cell's nucleus, built from a pair of centrioles set at right angles.
In practice
The centrosome duplicates before a cell divides, and its centrioles help pull duplicated chromosomes toward opposite ends.
Where people slip
A centriole's exact role stays unclear — cells missing the centrosome, and plant cells that lack it, still divide.
