CELL TRANSPORT REVIEW
Cell transport – Movement of molecules in and out of the cell
Match the definition on the left with the term on the right.
a. Passive transport
1. _____ Large wastes or cell products are released from inside to outside a cell
b. Diffusion
2. _____ Diffusion of water molecules through a selectively permeable membrane.
c. Dynamic equilibrium
3. _____ The transport of particles which requires the use of energy
d. Exocytosis
4. _____ A state reached when particles continue to move but in equal amounts
in and out of the cell.
e. Osmosis
5. _____ Large particles are surrounded by the membrane and taken into the cell.
f. Active transport
6. _____ Movement of any particles from an area of higher concentration to one
of lower concentration, with the concentration gradient.
g. Endocytosis
7. _____ The transport of particles which does not require energy
Circle the word or phrase that best completes the statement or answers the question.
8. The structure most responsible for maintaining cell homeostasis is the
cytoplasm
cell wall
mitochondria
plasma membrane
9. The plasma membrane (cell membrane) is made up of a(n)
cholesterol layer
enzyme layer
phospholipid bilayer
protein layer
10. Which of the following is NOT a form of passive transport?
facilitated diffusion
diffusion
endocytosis
osmosis
11. Diffusion continues until
equilibrium is reached
turgor pressure is reached
one side has more
12. If a cell is placed in salt water, water leaves the cell by
osmosis
diffusion
active transport
phagocytosis
13. A cell moves particles from a region of low concentration to a region of high concentration by
facilitated diffusion
osmosis
passive transport
active transport
For each scenario, answer the questions and draw an ARROW to illustrate the movement of molecules.
14. Easter egg coloring:
A blue food coloring tablet is placed in a cup of vinegar and water. After several seconds, the blue
tablet will begin to dissolve and will eventually spread evenly throughout the liquid.
beaker
a. The blue dye is traveling from a __________ to a _________ concentration.
b. Identify the type of transport illustrated in this scenario:
Water and vinegar
c. Does this movement of particles require energy?
Blue food color tablet
