Section 1

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
oxygen from our blooddiffuses into our cells. carbon dioxide diffuses from our cell into our blood
osmosisspecial type of diffusion. movement of water from area of high concentration to area of low concentration across semi permeable membrane
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
osmosis in plantsplant cells shrink, becomes SOFT when placed in HYPERTONIC solution. become SWOLLEN when placed in HYPOTONIC solution
