Cell Transport Mechanisms Essay
Cell Transport Mechanisms and Permeability
P R E - L A B Q U I Z 1. Circle the correct term. A passive process, diffusion / osmosis is the movement of solute molecules from an area of greater concentration to an area of lesser concentration. 2. A solution surrounding a cell is hypertonic if: a. it contains fewer nonpenetrating solute particles than the interior of the cell. b. it contains more nonpenetrating solute particles than the interior of the cell. c. it contains the same amount of nonpenetrating solute particles as the interior of the cell. 3. Which of the following would require an input of energy? a. diffusion b. …show more content…
Simulating Dialysis (Simple Diffusion)
1. To understand that diffusion is a passive process dependent upon a solute concentration gradient. 2. To understand the relationship between molecular weight and molecular size. 3. To understand how solute concentration affects the rate of diffusion. 4. To understand how molecular weight affects the rate of diffusion.
