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
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

Explanation:

• Osmosis is defined as the diffusion of water through a cell membrane.
• Passive transport is the movement of substances through the cell membrane without the use of cellular energy.
• Transport proteins are used to help substances enter or exit the cell membrane.
• Active transport requires energy to move materials through a cell membrane.
• Equilibrium occurs when the molecules of one substance are spread evenly throughout another substance to become balanced.
• Exocytosis is when a vacuole membrane fuses with the cell membrane and the contents are released.
• Endocytosis is when the cell membrane forms around another substance (e.g., how the amoeba gets its food).
• Diffusion is when molecules move from areas of high concentration to areas of low concentration.

3. a. transport protein
4. b. active transport
5. h. equilibrium
6. g. exocytosis
7. f. endocytosis
8. c. diffusion
