centrifuge
cell fractionation
A centrifuge is the instrument used to separate cell parts according to density. By spinning samples at high speeds, the centrifuge applies centrifugal force to separate components based on their differing densities, allowing for isolation of specific cell parts such as organelles.

What seperates the internal composition and the Cytoplasme (the liquid inside the cell holding all parts or organisms of the cell in place) of the cell from the external is the plasmic membrane. This membrane has many functions as it's strcuture helps it to move or squeeze into places the cell needs to go.
The membrane that separates the content of the cell from the surrounding environment is called the cell membrane or plasma membrane. It is a selectively permeable barrier that regulates the passage of substances in and out of the cell.
The Cell Membrane forms the outside boundary that separates the cell from its environment.
In cells without cell walls, the cell membrane forms an outside boundary that separates the cell from its environment!

A cell membrane, or cell wall.
There are more than one kind of cell. If it is an animal or bacteria cell, than the cell membrane separates it. If it is a plant cell, than the cell wall separates it. go to www.cellsalive.com for more on that
There are many parts of the cell. The nucleus is the control center for all activity. The cell membrane separates the cell from other cells. The mitochondria is the center of respiration of the cell. Vacuoles are clear fluid sacs that act as storage for food, waste, and minerals.
