Explanation:
Cellular fractionation consists of centrifugally separating the subcellular structures after cell disruption.

The space between the pylon and the tube wall should be sufficient to break the cells causing minimal damage to the organites. After cell disruption, the resulting paste-like material is centrifuged to separate the organelles. The smallest organelle that can be isolated in this type of process is the ribosomes.
