    Passive Transport

    • The movement of substances across cell membranes in passive transport is driven by Fick's Law of Diffusion.
    • The main factor that determines the rate of passive transport is the concentration gradient.
    • The net movement of material from an area of high concentration to an area with lower concentration is called diffusion.
    • Passive transport follows the laws of thermodynamics.
    • Passive transport is a type of membrane transport that does not require energy.
