Differences between diffusion and osmosis practice exercise 1

A teacher says, “Osmosis only happens in liquids, but diffusion happens in gases, liquids and even solids.” Explain what this means by giving an example of each process. (3 marks)

A learner sets up two experiments: one showing oxygen gas spreading in a room, and another with water moving into a dry grapes. She says both are examples of diffusion. Is she correct? Explain your answer using the key differences between the two processes. (1 mark)

A student puts sugar in water and sees it spread on its own. Later, the same student places a slice of potato in plain water and it swells. Explain the two processes taking place and give one difference between them. (2 marks)

Explain why osmosis only happens in liquids while diffusion can happen in gases, liquids, or solids. Use one example for each to show the difference. (3 marks)

A doctor explains that oxygen spreads in the lungs in all directions, but water in the body cells moves in only one direction. Explain why oxygen and water behave differently in terms of diffusion and osmosis. (3 marks)

A student says that osmosis and diffusion are both about movement from high to low concentration. Her friend disagrees and says there are more differences. List two differences and explain why the friend is correct. (3 marks)

During a science lesson, two students were asked to explain how nutrients and water enter a plant. One student said both move the same way—through diffusion. Do you agree with this answer? Give two reasons and an example. (4 marks)

Using the diagram below, answer the questions: a) Which beaker demonstrates osmosis and which one shows diffusion? (1 mark)b) What is the main visible difference in how the substances are moving? (1 mark)c) Which setup requires a membrane and why? (1 mark)

Two students are discussing the difference between osmosis and diffusion. One says both processes are the same because particles move from high to low concentration. Use examples and at least two differences to explain why the student is wrong.  (3 marks)

The diagram below shows oxygen molecules moving from high concentration outside a cell to lower concentration inside a cell. Next to it, water is shown passing through a membrane into a plant cell. Using the diagram, explain the two processes and give one major difference between them. (2 marks)
