OSMOSIS AND DIFFUSION REPORTSHEETDownload the report sheet, completeit, and then submit it as per instructions. Do not change the format.All blue shaded areas require answers.I.Osmosis Experiment (dry lab)There are 3 diagrams of animal cells (a, b, c) and 3 diagrams of plant cells (a, b, c) in solutions of varying tonicity. Label the diagrams as isotonic solution, hypertonic solution, or hypotonic solution. Animal cells: (a)Hypotonic(b)Isotonic(c)HypertonicPlant cells: (a)Hypotonic(b) Isotonic( c)Hypertonic II.Effect of temperature and size Observe the agar plate at 25°C, 30 min.

The molecular weight of Potassium Permanganate is less so it diffuses quickerName:Hang NguyenDate:10/07/15
