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