____
5. What is the main difference between active transport and passive transport?
a. During active transport the water inside the cell is used to transport substances throughout

and active transport moves substances using the cell’s energy.
c. Active transport moves substances from higher concentrations to lower concentrations and
passive transport moves substances from lower concentrations to higher concentrations.
d. Passive transport moves substances that are too large to get through the cell membrane by
forming a vesicle inside the cell and active transport forms the vesicle on the outside of the
cell.
____
6. Which of these have prokaryotic cells?
