VERIFIED 2025 CHEM 381 Cell Transport Review DETAILED QUESTIONS

Name: ______________________________________ Date: ____________

Cellular Transport
Match the term with its correct description:

a. energy e. active transport
b. facilitated diffusion f. channel protein
c. equilibrium g. passive transport
d. osmosis h. diffusion
1. ________ Transport protein that provides an opening or doorway in the plasma membrane
through which particles can diffuse
2. ________ Is used during active transport but not passive transport
3. ________ Particle movement from an area of higher concentration to an area of lower
concentration
4. ________ A form of passive transport that uses transport proteins
5. ________ Particle movement from an area of lower concentration to an area of higher
concentration
6. ________ The diffusion of water through a cell membrane
7. ________ The movement of substances through the cell membrane without the use of cellular
energy
8. ________ When the molecules of one substance are spread evenly throughout another
substance to become balanced

Label the following as True or False:

9. _______ The cell membrane is the organelle that is involved with helping homeostasis.
10. _______ Semi permeable membrane and plasma membrane are other names for cell
membrane.
11. _______ Gases, wastes, sugar, water and salts can pass directly through the membrane.
12. _______ Solute is the substances that does the dissolving.
13. _______ If concentration of solute is greater outside the cell; water will enter the cell and cause
the cell to swell.
14. _______ If concentration of solute is equal both outside and inside the cell, the cell is at
equilibrium.
15. _______ If concentration of solute is greater inside the cell; water will enter the cell cause the
cell to swell.

Fill in the missing percentages, draw an arrow to show the direction of water flow, and circle the type
of solution in each container.
