Talk about the basal bodies.

Located at the bases of the cilia and flagella have same cross-section as the cetrioles however some are extended to form cilium or flagellum core called axoneme. Centrioles and basal bodies have same structure and components since they can regenerate each other, in the spermatid,centriole derived basal body is the origin of the flagellum formation. So basal bodies are involved in production of microtubules which are in flagellum and cilia.
