Cellular Transportation Quiz-Take Home due 12/9 @beginning of class
Directions: Place multiple choice answers to the left of the question number. You may use your notebook,
though you should not need to do so. (1 pt)
1. T or F Simple diffusion and facilitated diffusion do not cause the cell to “spend” any energy.
2. T or F Na+/K+ ATPase pumps are examples of passive transport.
3. T or F The prefix iso- means under.
4. At what point in the process of diffusion is dynamic equilibrium reached?
a. when the movement of the molecules stops being random
b. when the molecules are mixed and stop moving
c. when the rate of change in the solution slows by one half
d. when there is continuous movement but no change
5.
The animal cell below is placed in a hypotonic solution. What can happen to damage the cell?
a. osmosis was prevented in the cell
c. the cell was damaged by bacteria
b. osmotic pressure causes the cell to rupture d. osmosis caused the cell to shrivel

concentration?
a. selective permeability
c. facilitated diffusion
b. osmosis
d. dynamic equilibrium
8.
Why does misting fruits and vegetables with water help them look fresh?
