SEPERATING THE ORGANELLES.
1- The cell fragments are poured into a test tube. The tube is put into a centrifuge (machine which spins) and is spun at a low speed. The heaviest oraganelles are flung to the bottom of the test tube by the centrifuge. Forming the pellet and the rest of the organelles are suspended in the supernatant.
2- The supernatant is drained off and poured into another tube, which is spun at a higher speed and the heavist organelles are flung to the bottom of the test tube.
This process is then repeated at higher speeds untill all the organelles are sperated.
