  1. Unit 3“Cell Transport” Vocabulary Review 10 Words

  2. A solution that has a lower concentration of solute outside than inside the cell, causing water to flow into the cell by osmosis. * Swell or Explode*

  3. Hypotonic A solution that has a lower concentration of solute outside than inside the cell, causing water to flow into the cell by osmosis. * Swell or Explode*

  4. Regulation of an organism’s internal environment to maintain conditions needed for life. * Stable/balanced*

  5. Homeostasis Regulation of an organism’s internal environment to maintain conditions needed for life. * Stable/balanced*

  6. Diffusion of water across a selectively permeable membrane.

  7. Osmosis Diffusion of water across a selectively permeable membrane.

  8. Energy-requiring process by which substances move across the plasma membrane against a concentration gradient. * Walking up a hill*

  9. Active Transport Energy-requiring process by which substances move across the plasma membrane against a concentration gradient. * Walking up a hill*

  10. Flexible, selectively permeable boundary that helps control what enters and leaves the cell.

  11. Plasma (Cell) Membrane Flexible, selectively permeable boundary that helps control what enters and leaves the cell.

  12. Net movement of particles from an area of higher concentration to an area of lower concentration.

  13. Diffusion Net movement of particles from an area of higher concentration to an area of lower concentration.

  14. Passive transport of ions and small molecules across the plasma (cell) membrane by transport proteins. *No Energy*

  15. Facilitated Diffusion Passive transport of ions and small molecules across the plasma (cell) membrane by transport proteins. *No Energy*

  16. A solution with the same concentration of water and solutes as inside a cell, resulting in the cell retaining its normal shape because there is no net movement of water.

  17. Isotonic A solution with the same concentration of water and solutes as inside a cell, resulting in the cell retaining its normal shape because there is no net movement of water.

  18. A solution that has a higher concentration of solute outside than inside a cell, causing water to leave the cell by osmosis. * Shrivel or Shrink*

  19. Hypertonic A solution that has a higher concentration of solute outside than inside a cell, causing water to leave the cell by osmosis. * Shrivel or Shrink*

  20. A separation between areas that have different solute concentrations, sometimes separated by a barrier like a membrane

  21. Concentration Gradient A separation between areas that have different solute concentrations, sometimes separated by a barrier like a membrane
