1. Make the assumption that a cell has a 10% salt concentration inside its cytoplasm. What would happen to that cell if it were placed in an environment that has a 50% salt concentration? What process is responsible for that reaction?
2. What would happen to that same cell if it were placed in an environment that was pure 100% water?
3. What factors do you think would influence the rate of diffusion?
4. What factors do you think would influence the rate of osmosis?
5. Why are carrier proteins required for the passage of some material in and out of the cell?
