A solution with the same concentration of water and solutes as inside a cell, resulting in the cell retaining its normal shape because there is no net movement of water hypotonic solution a solution with a solute concentration that is less than that inside the cell, which causes a net movement of water into the cell.
Lab #5: osmosis, tonicity, and concentration diffusion, osmosis, and tonicity simple diffusion particles in solution are generally free to move there will be no more net diffusion of solute from one area to another, although random movement of particles will continue.

Diffusion lab - diffusion lab problem will starch, water, glucose, iodine or a combination of the above diffuse across the membrane of the dialysis bag causing the bag to either expand or shrivel. Lab 5 diffusion and osmosis lab 6 protein quantification lab 7 enzymes and concentration gradient on the rate of diffusion or osmosis wait until the potato cylinders reach equilibrium and measure the change in weight since the solute concentration of outside solution is known, one can determine the concentration of solute in potato. Diffusion is the movement of solutes from an area of high concentration to low concentration and does not require energy input by cells osmosis is the movement of water through membranes water moves from areas of high potential (high free water concentration) to low solute concentration (low free water concentration.
