Question Answer
cell membranesemi permeable membrane acts a barrier to only allow particles of certain size to pass through, only allow small uncharged molecules to pass through but not large/charged
diffusionmovement of particles from area of high concentration to low concentration across cell membrane
osmosisis the movement of water or other solvent through a plasma membrane from a region of low solute concentration to a region of high solute concentration
hypertonic solutiongreater concentration of water INSIDE of the cell. water moves into cell, cell gets bigger can burst
hypotonic solutionhigher concentration of water OUTSIDE of the cell. water leaves the cell, cell shrinks
isotonic solutionthere is an equal concentration of water in cell and solution. water moves in and out equally. cell stays the same
