Complete the table by checking the correct column for each statement:
Statement
Isotonic
Hypotonic
Hypertonic
solution
solution
solution
Causes a cell to swell
Doesn’t change the shape of a
cell
Causes osmosis
Causes a cell to shrink
Match the term with its correct description:
a. energy
b. facilitated diffusion
c. endocytosis
d. passive transport
e. active transport
f. exocytosis
g. carrier protein
h. channel protein
________ Transport protein that provides a tube-like opening in the plasma
membrane through which particles can diffuse
________ Is used during active transport but not passive transport
________ Process by which a cell takes in material by forming a vacuole around
it
________ Particle movement from an area of higher concentration to an area of
lower concentration
________ Process by which a cell expels wastes from a vacuole
________ A form of passive transport that uses transport proteins
________ Particle movement from an area of lower concentration to an area of
higher concentration
________ Transport protein that changes shape when a particle binds with it
Match the term with its correct description:
a. transport protein
d. passive transport
b. active transport
e. osmosis
c. diffusion
f. endocytosis
g. exocytosis
h. equilibrium
_____ The diffusion of water through a cell membrane
_____ The movement of substances through the cell membrane without the use
of cellular energy
_____ Used to help substances enter or exit the cell membrane
_____ When energy is required to move materials through a cell membrane
_____ When the molecules of one substance are spread evenly throughout
another substance to become balanced
_____ A vacuole membrane fuses (becomes a part of) the cell membrane and the
contents are released
_____ The cell membrane forms around another substance, for example, how the
amoeba gets its food
_____ When molecules move from areas of high concentration to areas of low
concentration
Label the diagrams of cells using the following terms: diffusion, active transport,
osmosis, facilitated diffusion, or equilibrium. The arrows show the direction of
transport. You may use the terms more than once!

2 H2O molecules
Low CO2 levels
High

5 glucose molecules
10 H2O

Low protein levels
10 H2O molecules
Osmosis Practice Activity
Osmosis is the diffusion of water from an area of high concentration to an area of low concentration.
Only water moves in osmosis! The diagrams below show the concentration of water and salt inside
the cell and the concentration of water and salt surrounding the cell. Complete the sentences below
by comparing the concentration of the water inside the cell and the concentration outside the cell.
1.
5% NaCl
95% H2O
95% NaCl
5% H2O
a. Water will flow _____________________ (into
the cell, out of the cell, in both directions).
b. The cell will ______________________ (shrink,
burst, stay the same).
2.
5% NaCl
95% H2O
5% NaCl
95% H2O
a. Water will flow _____________________ (into the cell,
out of the cell, in both directions).
b. The cell will ______________________ (shrink, burst,
stay the same).
a. Water will flow _____________________ (into the
cell, out of the cell, in both directions).
3.
95% NaCl
5% H2O
5% NaCl
95% H2O
b. The cell will ______________________ (shrink,
burst, stay the same).
4. At which solution of concentration gradient is each cell diagram? (Hypotonic, Hypertonic, Isotonic)
a. _____________
b. ________________
c. ____________
5. This diagram is moving from a high to a low concentration: ___________________
6. Using a transport protein to move particles across the membrane: ___________________
7. Describe the processes occurring in the following pictures:
8. Define homeostasis.
9. What role does the cell membrane play in maintaining homeostasis?
10. How is facilitated diffusion different from diffusion? How are they similar?
11. List two ways that active transport is different than passive transport.
1) _________________________
2) _________________________
12. Why is the sodium-potassium pump considered an active transport? Which direction are the
sodium and potassium bing pumped? How many sodiums are being pumped? How many
potassiums are being pumped?
13.
14. What are the 5 functions of the cell membrane?

15. Label the Phospholipid. Include
the terms: Phosphate Head, Fatty Acid Tail,
Hydrophilic, Hydrophobic
16. On the front of this page, define the words in each box in your own words. Then, on the back,
draw a picture of each using 4 colors.
Active Transport
Semi Permeable
Cell Membrane
Diffusion
