  1. Chapter 8.1Osmosis Yes…osmosis and diffusion are different

  2. Remember Diffusion?? • Movement of particles from high concentration to low.

  3. osmosis • The diffusion of water • What is diffusion??? Hint: We just said it.

  4. The Tonics • Isotonic---water flow is equal • Hypotonic---water flows into cell • Hypertonic---water flows out of cell.

  5. Isotonic solution • Concentrations of dissolved particles (solute) are the same both inside and outside the cell.

  6. Hypotonic solution • Concentration of dissolved particles is lower outside the cell than inside.

  7. Hypertonic solution • Concentration of dissolved particles is higher outside the cell than inside

  8. What happens to cells in these solutions?

  9. Facilitated diffusion • Particles that need to be moved are unable to do so on their own. • They rely on channel or transport proteins to carry them

  10. Passive transport • Does not require energy to move substances across membranes • Substances move with a concentration gradient (high to low) • Examples – diffusion, osmosis, facilitated diffusion

  11. Active transport • Moves particles from an area of low concentration to an area of high concentration • Requires energy

  12. Transport of large particles • Endocytosis (stuff coming in...enter) • Exocytosis (stuff going out...exit) • Both processes require energy because they change the membrane of the cell
