solution
Causes a cell to swell
Doesn’t change the shape of a cell
Causes osmosis
Causes a cell to shrink
Directions: Match the term with its correct description:
energy
facilitated diffusion
endocytosis
passive transport
active transport
exocytosis
carrier protein
channel protein
1. Answer here Transport protein that provides a tube-like opening in the plasma membrane through
which particles can diffuse
2. Answer here Is used during active transport but not passive transport
3. Answer here Process by which a cell takes in material by forming a vacuole around it
4. Answer here Particle movement from an area of higher concentration to an area of lower
concentration
5. Answer here Process by which a cell expels wastes from a vacuole
6. Answer here A form of passive transport that uses transport proteins
7. Answer here Particle movement from an area of lower concentration to an area of higher
concentration
8. Answer here Transport protein that changes shape when a particle binds with it
Directions: Match the term with its correct description:
transport protein
passive transport exocytosis
active transport
osmosis
equilibrium
diffusion
endocytosis
9. Answer here The diffusion of water through a cell membrane
10. Answer here The movement of substances through the cell membrane without the use of cellular
energy
11. Answer here Used to help substances enter or exit the cell membrane
12. Answer here When energy is required to move materials through a cell membrane
13. Answer here When the molecules of one substance are spread evenly throughout another substance to
become balanced
14. Answer here A vacuole membrane fuses (becomes a part of) the cell membrane and the contents are
released
15. Answer here The cell membrane forms around another substance, for example, how the amoeba gets
its food
16. Answer here When molecules move from areas of high concentration to areas of low concentration
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.
