Across
  1. 4. type of embedded protein that provides a tunnel-like opening in the plasma membrane through which particles can diffuse
  2. 5. the separation of smaller particles from larger particles by diffusion through a semi-permeable membrane
  3. 6. the process by which some cells surround and take in materials
  4. 11. a difference in concentration of particles on opposites sides of a membrane
  5. 14. Particle movement from an area of higher concentration to an area of lower concentration, includes diffusion and osmosis
  6. 18. a solution in which the concentration of dissolved substances is the same as the concentration inside a cell
  7. 20. a form of endocytosis in which the cell takes in fluids ("cell drinking")
  8. 23. the passive movement of particles along a concentration gradient until they are evenly distributed (like a lump of sugar that dissolves in a beaker of water)
  9. 24. a form of endocytosis in which the cell takes in solid particles ("cell eating")
Down
  1. 1. what happens to a cell placed in a hypotonic solution
  2. 2. a solution in which the concentration of dissolved substances is higher than the concentration inside a cell
  3. 3. movement of materials that requires energy because it moves materials against the concentration gradient
  4. 7. process by which cells remove materials from the cell by a vacuole that never really passes through the membrane
  5. 8. the tendancy of a cell or an organism to attempt to maintain a constant environment
  6. 9. protein that changes shape when a particle binds with it, involved in facilitated diffusion
  7. 10. form of passive transport that uses a carrier protein
  8. 12. the diffusion of water
  9. 13. when the concentration of substances on opposite sides of a membrane are the same
  10. 15. when a solution is created, the substance into which particles dissolve
  11. 16. type of protein that is involved in active transport
  12. 17. when a solution is created, the particles that are dissolved in the solvent
  13. 19. a solution in which the concentration of dissolved substances is lower than the concentration inside a cell
  14. 21. what happens to a cell placed in a hypertonic solution
  15. 22. is used during active transport but not passive transport
