    Introduction: The purpose of this lab was to observe passive transport of molecules through diffusion and osmosis. We had to keep close observation on two dialysis bags and explain how we measured the change in weight as diffusion and osmosis occurred throughout the experiment. Cells produce an energy called Kinetic Energy.  This causes molecules of the cell to move around and bump into each other. Diffusion is one result of this molecular movement.  Diffusion is the passive movement of molecules

    Osmosis and diffusion are sometimes mixed up without much thought‚ but they are very different in many ways. Osmosis is a defined as the movement of water through a semipermeable membrane (). The membrane is fully permeable for the small water molecules‚ but is selectively permeable to any substance that is lager that a normal water molecule. One example might be a glucose and water mixture‚ when the solute is put into one side of a U-shaped tube that has a semipermeable membrane between the solvent

    Lab Topic: Movement of Materials Across the Cell Membrane—Potato Tuber Cells Introduction: Osmosis is a form of diffusion in which water diffuses through a selectively permeable membrane from a region of high concentration to a region of lower concentration. This form of diffusion takes place when the molecules in high concentration are too large to move through the membrane. Three factors that determine cell membrane permeability are shape‚ size‚ and polarity. For this experiment‚ it must
