Diffusion can be defined as the movement of particles from a _________ concentration to a _______ __________ concentration. 2. The process of diffusion is passive. What does this mean? 8. In which direction does water flow during the process of osmosis? 3. What is the equilibrium point in terms of diffusion? 9. During osmosis, water will always move in a direction to _______ the higher solute concentration. 4. Osmosis can be defined as_________ 5. What does selectively permeable mean? 6. Osmosis is different from diffusion in two major ways. What are they? 7. Briefly define solute, solvent and solution.
11. In a Hypertonic solution, water will move out of the cell because ______ The cell will ________ because it becomes dehydrated. 12. In an Isotonic solution, water will move in and out of the cell at _______ rates. The cell will not lyse or shrivel. 13. The process of _______ is used for molecules that cannot easily pass through the cell membrane. These molecules may be too large or cannot dissolve (insoluble) in lipids 14. The movement of molecules in facilitated diffusion are assisted by what type of proteins? 15. What does a passive process mean?
