Investigation of Osmosis in Potato chips Introduction In this investigation, I will be looking at how osmosis affects potato chips. I have researched on cell membranes: CELL SURFACE: PLASMA MEMBRANES OF 2 CELLS A thin membrane termed the plasma membrane enclosed the contents of all living cells and defines boundary between the contents of the cell and the surroundings. The plasma membrane is a continuous layer of LIPID and protein molecules, 8 to 10 nanometers (nm) thick that it acts as a selective barrier to regulate the cells chemical composition. Most water-soluble ions and molecules are unable to cross this barrier spontaneously and require a specific carrier protein or a channel made of protein to enable them to cross. In this way, the cell is able to maintain the concentration of ions and small molecules differences from those of their surroundings. Another mechanism, involving small membranes vesicles (fluid-filled sacs) that add...
