Biology coursework Osmosis investigation: to find out the concentration of cell sap within the vacuole of a potato cell. Planning Background info: Osmosis Definition Osmosis is the net movement of water from a dilute to a strong solution via a partially permeable membrane against the concentration gradient until equilibrium is reached. Movement is due to water having kinetic energy. The water moves into the vacuole as which is the part that contains cell sap (a salty/sugary solution). When the cell takes in water the vacuole increases in size, which pushes the cytoplasm into the cell membrane, which in turn pushes, the cell membrane into the cell wall. Partially permeable membrane: Each cell is surrounded by a cell membrane. It separates the contents of the cell from the outside. The cell membrane has tiny holes in it. This allows small molecules to pass through but not the large ones. The cell membrane is partially permeable-Osmosis is a special kind...
