- 1. Multiple Choice
You are a farmer growing crops. The concentration of your potatoes are 0.35M and you are advised to water your plants with a 0.35M saline solution to provide nutrients. What happens to the plant cells?
Cells are normal since this is an isotonic solution.
Cells become flaccid since this is an isotonic solution.
Cell become plasmolyzed since this is an isotonic solution.
- 2. Multiple Choice
You are a doctor. A patient comes in dehydrated. What type of solution would be best to place into their IV?
A hypotonic solution to allow the cells to rehydrate.
A slightly hypertonic solution to allow the cells to rehydrate.
An isotonic solution to increase fluid in the body without causing harm to the cells.
An isotonic solution to decrease fluid in the body without causing harm to the cells.
- 3. Multiple Choice
Which of the following describes an appropriate water movement pathway?
hypotonic solution to hypertonic solution
hypertonic solution to hypotonic solution
hypertonic solution to isotonic solution
isotonic solution to hypotonic solution
- 4. Multiple Choice
What is the difference between the molecule transported in facilitated diffusion versus simple diffusion?
facilitated diffusion involves nonpolar solute transport through a membrane protein
simple diffusion involves nonpolar solute transport through a membrane protein
facilitated diffusion involves polar solute transport through a membrane protein
simple diffusion involved polar solute transport through a membrane protein
- 5. Multiple Choice
Which of the following describes the difference between passive and active transport?
passive transport involves moving solutes against the concentration gradient using ATP.
active transport involves moving solutes against the concentration gradient using ATP.
passive transport involves moving solutes with the concentration gradient using ATP.
active transport involves moving solutes with the concentration gradient using ATP.
- 6. Multiple Choice
Which of the following describes the difference between channel and carrier transport proteins?
channel proteins bind to solute to shuttle the solute across the membrane
channel proteins provide a nonpolar channel through the membrane
carrier proteins bind to solute to shuttle the solute across the membrane
carrier proteins provide a nonpolar channel through the membrane
- 7. Multiple Choice
Describe what would happen if you placed an animal cell in 1.0 M solution.
The cell would lyse
The cell would be flaccid
The cell would shrivel
The cell would be normal
- 8. Multiple Choice
Describe what would happen if you placed a plant cell in a 0.0 M solution.
The cell would lyse
The cell would be turgid
The cell would plasmolyze
The cell would be flaccid
- 9. Multiple Choice
What organelle found in a plant cell provides the plant cell with turgid pressure?
Rough ER
Golgi Bodies
Central Vacuole
Lysosome
- 10. Multiple Choice
What property of the plasma membrane allows for oxygen and carbon dioxide to diffuse by simple diffusion?
Phospholipids are nonpolar allowing for small, nonpolar substances to dissolve.
Phospholipids are polar allowing for small, polar substances to dissolve.
Phospholipids are amphipathic allowing for a nonpolar interior for nonpolar substances to diffuse.
Phospholipids are amphipathic allowing for polar interior for polar substances to diffuse.
