Across
  1. 3. continuous movement w/ no overall change
  2. 4. secretion of materials at the plasma membrane
  3. 6. forms when a cell is placed in a solution that has a higher concentration of solute outside of the cell than on the inside
  4. 7. net movement of particles from an area where there are many particles of the substance to an area where there are fewer particles of the substance
  5. 9. diffusion of water across a selectively permeable membrane
  6. 10. forms when a cell is in a solution that has the same concentration of water & solutes as its cytoplasm
Down
  1. 1. transport movement of substances across the plasma membrane against a concentration gradient; requires energy
  2. 2. uses transport proteins to move other ions & small molecules across the plasma membrane
  3. 5. forms when a cell is in a solution that has a lower concentration of solute
  4. 8. cell surrounds a substance in the outside environment, enclosing the substance in a portion of the plasma membrane
