Tissue Quizzes & Trivia

Transport processes is a vague term given to the movement of a substance from one place to another, such as energy (heat conduction), momentum (fluid flow), mass (molecular diffusion) radiation and electricity. Today we’ll be looking at cells.


Questions and Answers
  • 1. 
    A solution w/ a lower concentration of dissolved solute particles than the cell
    • A. 

      Hypotonic solution

    • B. 

      Hypertonic solution

    • C. 

      Isotonic solution

    • D. 

      Diffusion solution

  • 2. 
    What are the 3 major components of the plasma membrane?
    • A. 

      Phospholipids, protein, plasma

    • B. 

      Phospholipids, cholesterol, and proteins

    • C. 

      Cholesterol, protein and polar head

    • D. 

      Phospholipids, ions, glucose

  • 3. 
    The solute pump
    • A. 

      Requires a molecule of ATP in order to move particles across the plasma membrane. for this reason, we say this is ACTIVE TRANSPORT.

    • B. 

      Is considered active transport because it requires energy

    • C. 

      Is the middle piece of the "orange-shaped" membrane on the diagram

    • D. 

      All of the above

  • 4. 
    The movement of molecules down a concentration gradient (from areas of high concentration to low concentration). No ATP (energy) is required, therefore it is a passive process.
    • A. 

      Osmosis

    • B. 

      Diffusion

    • C. 

      Isotonic

    • D. 

      Filtration

  • 5. 
    A solution w/ a concentration of solute particles is equal to the concentration of dissolved solute particles in the cell
    • A. 

      Hypertonic solution

    • B. 

      Hypotonic solution

    • C. 

      Isotonic solution

    • D. 

      Diffusion solution

  • 6. 
    The carrier protein and the protein channel do not require outside energy to move particles across the plasma membrane. For this reason, we say this process is...
    • A. 

      Active transport

    • B. 

      Bilayer transport

    • C. 

      Passive transport

    • D. 

      ATP transport

  • 7. 
    The diffusion of water molecules across a selectively permeable membrane; h2o (only) will go where there is a high concentration of solute particles. this is a passive process so no ATP is required.
    • A. 

      Filtration

    • B. 

      Diffusion

    • C. 

      Osmosis

    • D. 

      Isotonic

  • 8. 
    The plasma membrane
    • A. 

      Is the liquid substance that houses all the organelles

    • B. 

      Is housed inside the reproductive organs

    • C. 

      Is a selectively permeable organelle that cleans the cell of toxins and debris

    • D. 

      Is a selectively permeable phospholipid bilayer. it contains membrane proteins which assist the transport of molecules into and out of the cell

  • 9. 
    The main part of a solution the liquid or gas in which the solute is dissolved or suspended
    • A. 

      Solution

    • B. 

      Solute

    • C. 

      Solvent

  • 10. 
    A solution w/ a higher concentration of dissolved solute particles than the cell
    • A. 

      Osmosis solution

    • B. 

      Isotonic solution

    • C. 

      Hypotonic solution

    • D. 

      Hypertonic solution

  • 11.

    • B. 

      Openings would get larger, bigger cells get thru, blood in urine

    • C.
