  • Biology Movement of Molecules
    • Osmosis
      • Movement of water molecules.
      • Along concentration gradient, through partially permeable membrane.
      • Eg. in potatoes.
    • Diffusion
      • Any molecule.
      • Along concentration gradient.
    • Active Transport
      • Against concentration gradient.
      • Requires energy from respiration.
      • Allows cells to absorb sugar and ions which pass through a cell membrane from very dilute solutions
      • Eg. plant roots and small intestine.
