Question

match the term with its correct description:
a. transport protein
b. active transport
c. diffusion
d. passive transport
e. osmosis
f. endocytosis
g. exocytosis
h. equilibrium

______ 9. the diffusion of water through a cell membrane
______ 10. the movement of substances through the cell membrane without the use of cellular energy
______ 11. used to help substances enter or exit the cell membrane
______ 12. when energy is required to move materials through a cell membrane
______ 13. when the molecules of one substance are spread evenly throughout another substance to become balanced
______ 14. a vacuole membrane fuses (becomes a part of) the cell membrane and the contents are released
______ 15. the cell membrane forms around another substance, for example, how the amoeba gets its food
______ 16. when molecules move from areas of high concentration to areas of low concentration

Explanation:

Match descriptions 9 through 12

• Description 9: "The diffusion of water through a cell membrane" matches osmosis (e).
• Description 10: "The movement of substances through the cell membrane without the use of cellular energy" matches passive transport (d).
• Description 11: "Used to help substances enter or exit the cell membrane" matches transport protein (a).
• Description 12: "When energy is required to move materials through a cell membrane" matches active transport (b).

Match descriptions 13 through 16

• Description 13: "When the molecules of one substance are spread evenly throughout another substance to become balanced" matches equilibrium (h).
• Description 14: "A vacuole membrane fuses (becomes a part of) the cell membrane and the contents are released" matches exocytosis (g).
• Description 15: "The cell membrane forms around another substance, for example, how the amoeba gets its food" matches endocytosis (f).
• Description 16: "When molecules move from areas of high concentration to areas of low concentration" matches diffusion (c).
