      Centrosomes are microtubule organizing centres and essentially the spot where centrioles are. Centrioles, nobody knows what they do

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

You've got it spot on. Amazing! Thank you for your help. I'm confident of passing (touch wood).

    This Video helped so much. It sucks when your teachers have lessons on stuff like this ( like new stuff) on days when I'm not there...sick...
