This is a great review for Cellular Transport. This information WILL be on the semester exam!
CELLULAR TRANSPORT REVIEW
Helpful Hints:
Hypo =Hippo: The cell will swell
If you are ACTIVE…you are using energy
If you are passive…you are NOT using energy
Remember “Salt Sucks” water will always move too where there is more solute.
Match the definition on the left with the term on the right.
1. _____ release of wastes or cell products from inside to outside a cell
2. _____ diffusion of water molecules through a selectively permeable membrane
3. _____ loss of water from a cell resulting in a drop in turgor pressure in plants. Plasma
membrane detaches from the cell wall
4. _____ continuous movement of particles but no overall change in concentration
5. _____ movement of particles from an area of higher concentration to one of lower
concentration
In the space at the left, write true if the statement is true. If the statement is false, change the italicized term to
make the statement true. Write this answer in the blank provided.
_______________ 7. A solution in which the concentration of dissolved substances is lower than the concentration
inside a cell is hypertonic.
_______________ 8. The internal pressure of a plant cell is called turgor pressure.
_______________ 9. In passive transport, the movement of particles across a membrane requires energy.
_______________ 10. Endocytosis is a process by which a cell membrane surrounds and takes in material from
the environment.
_______________ 11. The passive transport of material across a membrane by means of transport proteins is
called activated diffusion.
_______________ 12. A membrane that allows only some materials to pass through shows selective permeability.
Highlight or circle the word or phrase that best completes the statement or answers the question.
13. The structure most responsible for maintaining cell homeostasis is the
cytoplasm cell wall mitochondria cell membrane
14. A cell membrane is made up of a(n)
cholesterol layer enzyme layer lipid bilayer protein layer
15. Which of the following is not a form of passive transport?
facilitated diffusion diffusion endocytosis osmosis
16. Diffusion continues until
equilibrium is reached turgor pressure is reached one side has more
17. If a cell is placed in salt water, water leaves the cell by
osmosis diffusion active transport phagocytosis
18. If it is not watered, a tulip plant wilts because it
increases active transport loses turgor pressure increases turgor pressure
19. A cell moves particles from a region of lesser concentration to a region of greater concentration by
facilitated diffusion osmosis passive transport active transport
20. What organelle produce the energy required in active transport?
21. What organelle plays a large role in exocytosis by packaging proteins into vesicles?
22. If a cell normally contain 70% solute inside. If the outside solution has 60% solute what happens?
23. When molecules move with the concentration gradient it means they are moving from _______________to
____________concentration
24. Define equilibrium:
a. diffusion
b. equilibrium
c. exocytosis
d. osmosis
e. plasmolysis
