    Match the transport process to the definition. Things move along their concentration gradient from higher to lower concentration, these "things" have properties that allow them to move in and out of the cell as if there were no barrier. This describes
    • A. 

      Osmosis

    • B. 

      Facillitated diffusion

    • C. 

      Active transport

    • D. 

      Simple diffusion

  • 14. 
    Match the transport process to the definition. The movement of water across a semi-permeable membrane along its concentration gradient. 
    • A. 

      Osmosis

    • B. 

      Facillitated diffusion

    • C. 

      Active transport

    • D. 

      Simple diffusion

  • 15. 
    Match the transport process to the definition. The substance being transported is following its concentration gradient, but it is too large, too polar, or both to cross the membrane. In order for it to cross, a specific transmembrane transport protein will open in order to allow for diffusion to proceed without use of energy. 
    • A. 

      Osmosis

    • B. 

      Facillitated diffusion

    • C. 

      Active transport

    • D. 

      Simple diffusion

  • 16. 
    Match the transport process to the definition. Molecules are "pumped" from areas of lower concentration to areas of higher concentration. This requires a selective transport protein, one that can hydrolyze ATP for energy. This process requires energy in order for transportation to take place. 
    • A. 

      Osmosis

    • B. 

      Facillitated diffusion

    • C.
