Cell Environments Worksheet

Cell Environments: How Cells Interact with Their Surroundings

Read each question carefully and answer to the best of your ability. Use the provided diagrams to help you visualize the concepts.

1. What is the process by which particles move from an area of higher concentration to an area of lower concentration?

2. The movement of water across a semipermeable membrane from an area of high water concentration to an area of low water concentration is called:

3. The cell membrane is  , meaning it only allows certain substances to pass through.

4. When a plant cell is placed in a concentrated salt solution, water will move   the cell, causing the cell to shrink.

5. Animal cells placed in pure water may   due to too much water entering the cell.

6. Diffusion requires the cell to use energy.

7. The cell wall in plant cells helps prevent them from bursting when they absorb too much water.

8. Observe the diagram of the plant cell. Explain how its cell wall helps maintain its shape in different water environments.

9. Observe the diagram of the animal cell. Why is it more vulnerable to bursting in pure water compared to a plant cell?

Match each term with its definition.
