TYPES OF TRANSPORT

    Cards (6)

    • Passive Transport
      Type of transport that uses no energy.
    • Simple Diffusion
      Passive Transport
      • materials flow from high concentration area to low concentration area without using energy
      • related to osmosis, which involves transport of solvent molecules across a semipermeable membrane from a region of high to low concentration.
    • Facilitated Diffusion
      Materials flow from an area of high concentration to an area of low concentration without using energy and with the help of transport proteins.
    • Osmosis
      Water moving from an area of higher concentration to an area of lower concentration. This happens across a semipermeable membrane, a membrane that only lets certain molecules pass through.
      • Hypotonic Solution - lower concentration of solute than cell, making it swell as water enters
      • Hypertonic Solution - higher concentration of solute than cell, making it shrink as water leaves
      • Isotonic Solution - has equal concentration, therefore the cell neither shrinks nor swells
    • Active Transport
      Type of transport that requires energy. Materials flow from an area of low concentration to an area of high concentration with the use of energy.
    • Bulk Transport
      The transport of materials through the use of vesicles.
      • Phagocytosis - cell eats a particle by packaging it into a food vacuole
      • Pinocytosis - cell drinks extracellular fluid into tiny vesicles
      • Endocytosis - cell "eats and drinks" particles and fluids through the help of receptors
