Centrioles are cylindrical structures involved in the generation of microtubules—fibers inside of cells that form a network to provide structure and shape to cells and to mediate transport processes. In addition, centriole are required to build cilia, hair-like extensions on the cell surface that allow cells to receive and respond to signals from the outside.
