Cell Environments Worksheet

Cell Environments: Osmosis and Diffusion

Read each question carefully and answer to the best of your ability. This worksheet covers how different environments affect cells through processes like osmosis and diffusion.

1. The movement of water molecules across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration is called  .

2. The process by which molecules move from an area of higher concentration to an area of lower concentration is called  .

3. A cell placed in a   solution will swell and potentially burst because water moves into the cell.

4. A cell placed in a   solution will shrink as water moves out of the cell.

5. Which part of the cell controls what enters and leaves the cell?

6. Why might a plant cell not burst in a hypotonic solution, while an animal cell might?

7. Diffusion requires energy from the cell to move molecules.

8. In an isotonic solution, there is no net movement of water across the cell membrane.

9. Describe the key difference between osmosis and diffusion.

10. Label the animal cell diagram below with 'Cell Membrane', 'Nucleus', and 'Cytoplasm'.

11. Label the plant cell diagram below with 'Cell Wall', 'Cell Membrane', and 'Vacuole'.
