Osmosis and Tonicity Worksheet

Osmosis and Tonicity

Read each question carefully and answer to the best of your ability. Good luck!

1. What is the movement of water across a semi-permeable membrane from an area of high water concentration to an area of low water concentration called?

2. What type of solution would cause an animal cell to swell and burst?

3. In an   solution, the concentration of solutes is the same inside and outside the cell.

4. When a plant cell is placed in a hypertonic solution, it will lose water and its cell membrane will pull away from the cell wall, a process called  .

5. Osmosis is the movement of solutes from a high concentration to a low concentration.

6. A hypotonic solution has a higher concentration of solutes than the cell.

7. Explain what will happen to a plant cell if it is placed in a hypotonic solution. Use the diagram below to help your explanation.

8. Describe the difference between a hypertonic and an isotonic solution in terms of water movement across a cell membrane.
