Diffusion and osmosis

• What is diffusion?


  Diffusion is the movement of particles from an area of high concentration to an area of low concentration.
• What is osmosis?


  Osmosis is the movement of water molecules from an area of lower solute concentration to an area of higher solute concentration across a semi-permeable membrane.
• What is hypertonic?


  When the concentration of a solution is higher than the cell
• What is hypotonic? 


  When the concentration of a solution is lower than the cell.
• What is Isotonic?


  Isotonic refers to a solution that has the same concentration of solutes as the cell or tissue it is in.
• If a cell is put in a hypotonic solution, what does it do?


  Swells and absorbs
• If a cell is put in a isotonic solution, what does it do?


  Stays the same
• If a cell is put in a hypertonic solution, what does it do?
