Read each question carefully and answer to the best of your ability. This worksheet will test your understanding of osmosis, diffusion, and tonicity.
1. What is the movement of water molecules across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration called?
Diffusion
Active Transport
Osmosis
Facilitated Diffusion
2. A cell placed in a hypotonic solution will likely:
Shrink
Swell
Stay the same size
Burst immediately
3. The net movement of particles from an area of higher concentration to an area of lower concentration is called .
4. A solution with a higher solute concentration than inside the cell is called a solution.
5. Explain the difference between diffusion and osmosis.
6. In an isotonic solution, there is no net movement of water across the cell membrane.
True
False
7. Plant cells have a cell wall that prevents them from bursting in a hypotonic solution.
True
False
8. Observe the image below of an animal cell. If this cell is placed in a hypertonic solution, what will happen to it? Draw what you expect the cell to look like.
