Transport in cells

    Cards (4)

    • What is osmosis
      The movement of water particles from an area of high concentration to an area of low cocentration down a concentration gradient through a semi permeable membrane
    • What is active transport
      Movement of molecules from a low concentration to a high concentration against their concentration gradient, this requires energy
    • What is diffusion
      Movement of molecules from an area of high concentration to an area of low concentration down a concentration gradient
    • Factors affecting diffusion
      Temperature, concentration, surface area
