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