Biology Practical Assessment Aim To find the water potential of a potato cell. Theory This experiment will involve the process of osmosis. Osmosis is the movement of water molecules from an area of low concentration of dissolved stuff to an area of higher concentration of dissolved stuff through a selectively permeable membrane. More O molecules (which represent water) are moving to the right than the left because there are more X's and less O's on the right than on the left. The movement of O's will continue until both sides have equal concentrations. Equipment * 1 Potato * 1 Hole Cutter * 1 Tile * 1 Scalpel * 6 Test Tubes/Beakers * Test Tube Holder (for Test Tubes) * 1 Stop Watch or Clock * Paper Towels * 1 Scale (for weighing) Method Cut 6 pieces of potato using the hole cutter for a potato. Make them roughly the same size with no potato skin on them at all. Weigh and record the weight...
