A bound pair of centrioles make up a centrosome. The centrioles are the cylinders made up of 9 triplets of microtubules.

I'm using the video as a reinforcement tool, but I find myself correcting centrosome and centromere the entire time. Slowwww downnnn!

Understanding the differences is crucial for the MCAT. Ex: In Mitosis, each chromosome is lined up on the metaphase plate by 2 spindle fibers (one from each pole). In Meiosis, homologous chromosomes are lined up across from each other at the metaphase plate for Metaphase 1 and are held by 1 spindle fiber. I wanted to say this because I don't think this video mentions that huge detail :)
