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