centriole

A centriole is a small, cylindrical structure found inside most animal cells, playing a key role in cell division. Typically occurring in pairs, centrioles help organize the microtubules that form the cell's skeleton and ensure the accurate separation of chromosomes when a cell divides. They are part of the centrosome, serving as a hub for organizing the machinery necessary for cell replication. While their exact functions are complex and still being studied, centrioles are essential for maintaining proper cell structure and ensuring healthy cell division.
