  1. Types of Transport Review

  2. The movement of particles against the direction of diffusion requiring cell energy. ACTIVE TRANSPORT

  3. True or False?During diffusion molecules tend to move down the concentration gradient. TRUE

  4. DIFFUSION

  5. General transport method by which most molecules move across the membrane. DIFFUSION

  6. A difference in concentration across a cell’s membrane. CONCENTRATION GRADIENT

  7. Endocytosis of solid substances like bacteria and food. PHAGOCYTOSIS

  8. FACILITATED DIFFUSION

  9. A liquid mixture that involves the combination of a solvent with a solute. SOLUTION

  10. Active transport of molecules out of a cell. EXOCYTOSIS

  11. HYPERTONIC

  12. The movement of particles from high to low concentration. DIFFUSION

  13. An equal amount of a substance inside the cell and the environment the cell is living in. ISOTONIC

  14. OSMOSIS

  15. The diffusion of water across a cell membrane. OSMOSIS

  16. Endocytosis of liquids. PINOCYTOSIS

  17. Active transport of molecules into a cell. ENDOCYTOSIS

  18. The substance dissolved in the liquid part of the solution. SOLUTE

  19. HYPOTONIC

  20. The movement of a substance from high to low concentration without energy. PASSIVE TRANSPORT

  21. Type of membrane that allows ALL substances to pass through it. PERMEABLE

  22. ACTIVE TRANSPORT

  23. The liquid into which the solute is dissolved. SOLVENT

  24. To be in balance or in a state of equality. EQUILIBRIUM

  25. Type of membrane that allows only SOME substances to pass through it. SEMI-PERMEABLE (selectively)

  26. More solute, less water inside the cell than the environment the cell is living in. HYPOTONIC

  27. A type of membrane that allows NO substances to pass through it. IMPERMEABLE

  28. How does a water molecule enter and exit a cell? OSMOSIS

  29. How do most sugar molecules enter and exit a cell? ACTIVE TRANSPORT

  30. ACTIVE TRANSPORT

  31. More solute, less water outside the cell than inside the cell. HYPERTONIC

  32. Can you identify two differences between active and passive transport? • TYPE OF SUBSTANCES • CONCENTRATION GRADIENT • ENERGY – YES or NO?

  33. Can you identify the methods of transport that do NOT require energy by the cell? PASSIVE TRANSPORT • DIFFUSION • OSMOSIS

  34. ISOTONIC

  35. What factors can control the rate of diffusion? • TYPE OF MEMBRANE • CONCENTRATION GRADIENT • SIZE OF SUBSTANCE • TEMPERATURE • ACTIVITY LEVEL

  36. In what direction do substances naturally travel? HIGH TO LOW CONCENTRATION

  37. What cell structure controls diffusion and osmosis? CELL MEMBRANE

  38. Your life depends on . . . Active Transport!
