The centrosome basically functions in our cell cycle. It helps the cell divide. So during our interface of the cell cycle, we replicate our centrosome. And during our ProPhase, the centrosome basically migrates to both ends and then they create or extend those microtubules that grab our chromosomes and separate those chromosomes during cell division. Now, the centrosome is also involved in organizing and creating and extending the microtubules that constitute our cytoskeleton. Remember, the cytoskeleton is basically the scaffolding of our cell.
