Read each question carefully and answer to the best of your ability. Show all your work where applicable.
1. Which of the following best describes the movement of water during osmosis?
From a region of lower solute concentration to a region of higher solute concentration.
From a region of higher solute concentration to a region of lower solute concentration.
Against the concentration gradient, requiring energy.
Only through active transport pumps.
2. Diffusion is the net movement of particles from an area of:
Lower concentration to higher concentration.
Higher concentration to lower concentration.
Equal concentration to unequal concentration.
Across a selectively permeable membrane only.
3. The movement of molecules from an area of higher concentration to an area of lower concentration is called .
4. is the diffusion of water across a selectively permeable membrane.
5. A solution with a higher concentration of solutes than the cell cytoplasm is called a solution.
6. Diffusion requires energy input from the cell.
True
False
7. Plant cells swell and burst when placed in a hypotonic solution.
True
False
8. Explain the difference between osmosis and diffusion.
9. Describe what happens to an animal cell when placed in an isotonic solution. Why is this important for bodily functions?
10. Observe the diagram below, which represents a cell in a solution. Based on the movement of water molecules (indicated by arrows), what type of solution is the cell placed in (isotonic, hypotonic, or hypertonic)? Explain your reasoning.
