How basal bodies differ from centrioles?

Centrioles and basal bodies are characterized by their nine sets of triplet microtubule that are arranged in a cylindrical structure. Although the two structures are analogous in their triplet microtubule organization, their functions are unique. Centrioles function at the centrosomes to organize cellular microtubules, whereas basal bodies organize the microtubules of cilia.  Centrioles and basal bodies interchange their functions during the cell cycle when a centriole transitions to a basal body during G0/G1 to organize the primary cilium.
