Biology centriole
WebFeb 18, 2024 · Centrioles are evolutionarily conserved microtubule-based organelles critical to form centrosomes and cilia, which act as microtubule-organizing, signaling and motility centers.

Centrioles migrate to opposite poles at the end of meiosis and then the centrioles duplicate in the new cell and during the S phase. One centriole grows from the parent centriole. Therefore, like in DNA replication the centriole replication is semi-conservative. – Patty Belloise.
