in the artificial cells to the diffusion rate using the phenolphthalein-NaOH agar and the HCl solution. Lab #2 was a model of diffusion and osmosis‚ in which we filled the model cells with different solutions and determined the rate of diffusion. In lab #3‚ the results demonstrated the interactions between selectively permeable membranes‚ water‚ and solutes and how they are important in cellular and organismal functions. In lab #1‚ the results showed the diffusion rate between the certain time period

LabMr.P/Pd. 63/17/14 Osmosis and Diffusion Lab Osmosis is a process where molecules pass through a semi permeable membrane from a less concentrated solution into a more concentrated one‚ equalizing the concentrations on each side of the membrane. Diffusion is the spreading of something more widely.During the osmosis and diffusion lab I tested what happens to a fresh egg when osmosis and diffusion across membranes. The eggs were placed in vinegar‚ distilled water‚ and then lastly syrup. The
