Cell Environments Worksheet

Cell Environments: How Cells Interact with Their Surroundings

Read each question carefully and answer to the best of your ability. Use complete sentences for short answer questions.

1. Which process involves the movement of water molecules across a semipermeable membrane from an area of higher water concentration to an area of lower water concentration?

2. What would happen to an animal cell if it were placed in a hypotonic solution?

1. The cell   is selectively permeable, controlling what enters and leaves the cell.

2. When a plant cell is placed in an isotonic solution, its turgor pressure will  .

3.   is the movement of particles from an area of higher concentration to an area of lower concentration.

1. Plant cells burst when placed in a hypotonic solution due to their rigid cell wall.

2. Active transport requires energy to move substances across the cell membrane.

1. Explain the difference between diffusion and osmosis.

2. Describe the function of the cell membrane in maintaining a stable internal environment for the cell.

Observe the diagrams below and answer the questions that follow.

1. Identify two structural differences between the animal cell and the plant cell that help them respond differently to their environments.

2. Based on the diagram of the cell membrane, how does its structure allow it to regulate the passage of substances?
