Centriole

/ˈsɛntriˌoʊl/ noun

Definition

A cylindrical organelle composed of microtubules that plays a key role in organizing the cell's microtubule network and forming the spindle apparatus during cell division. Usually found in pairs near the nucleus.

Etymology

From Latin 'centrum' meaning 'center' with the diminutive suffix '-ole', literally meaning 'little center'. Named in the early 1900s for their central location in the cell and their role in organizing cellular structures.

Kelly Says

Centrioles are like cellular construction foremen! They organize the building of microtubules throughout the cell and duplicate themselves before cell division to ensure each daughter cell gets its own set of organizational headquarters.
