Similarities between diffusion and osmosis practice exercise 1

A student observed two setups: one showing sugar spreading in water, and another showing water entering a dry seed. What similarity do both processes show in how substances move? (2 marks)

 In a science lesson, the teacher placed a potato chip in water and later sprayed perfume in the classroom. What is similar about the movement of particles in both situations? (2 marks)

A teacher explains that cells absorb oxygen through diffusion and take in water by osmosis. Describe one similarity between how these substances move into the cell. (1 mark)

The diagram below shows 2 set ups: One shows food dye spreading in a glass of water and the other shows water entering cells in a wilted leaf. Describe one thing that is the same in both processes, and explain how it helps the cell or system reach balance. (2 marks)

A learner placed sugar in tea and later soaked dry leaves in water. He noticed the sugar spread evenly and the leaves became firm again. Explain what is similar in both of these observations. Give reasons based on how substances move and whether energy is needed. (3 marks)

A learner said that osmosis is different from diffusion because it uses a membrane. Her classmate argued that the two are actually quite similar. Who is more accurate and why? (2 marks)
