Description
Osmosis, which refers to the specific movement of water molecules via partially permeable membranes and Diffusion which is the net movement of substances from regions of higher concentration to regions of lower concentrations meaning that diffusion is driven by the action of the concentration gradient. In this gcse Biology quiz, we are going to see how diffusion and osmosis work
You must have tried out this experiment in school. Place kitchen salt (NaCl) in a cavity of a potato tube and place it in water. The potato tuber will shrink as it loses water to the other solution.
With this said, you can go ahead and test your knowledge with the quizzes that have been brought together for you on this online revision platform. It is important to note that the quizzes on this platform are free of charge.
Good Luck
