    Lab report OSMOSIS TROUGH A SELECTIVELY PERMEABLE MEMBRANE Introduction: Molecules have kinetic energy.  This causes the molecules of the cell to move around and bump into each other. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane (a membrane...

  • Osmosis Lab Report
    Osmosis Lab Report Hypothesis: Osmosis will occur when there is an uneven distribution of solute in a solvent. The higher the solute in solvent, then there will be a higher rate of osmosis through the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal or no solute...

    hypotonic solutions exist, as well as how cells try to get back into an isotonic state. In doing so, this lab will allow reader to learn why and how diffusion and osmosis happens in all living things. The group of experimenters will be testing the movement of solutes from their area of high concentration...
