Investigation to determine the concentration 23rd September 02 of cell sap in potato tuber cells Aim- To determine concentration of cell sap in potato tuber cells Preliminary information- I will use osmosis to investigate the concentration of cell sap in potato tuber cells. Osmosis is the net movement of water particles across a partially permeable membrane from a region of high water concentration to an area of low water concentration. Molecules in a solution move in constant random motion because they have kinetic energy. The water molecules can travel through the pores in the cell membrane of the potato cells but sucrose particles are too big to get through since they contain more atoms (C12H22O11- twelve carbon, twenty-two hydrogen and eleven oxygen as opposed to H20- two hydrogen and one oxygen). Since they are in constant random motion the water molecules eventually move across the membrane to the area with less...
