PRE-LAB QUESTIONS1.A concentration gradient affects the direction that solutes diffusion. Describe how molecules move with respect to the concentration.2.How does size affect the rate of diffusion?3.Does polarity affect the rate of diffusion? Explain your answer.4.If a piece of celery is placed in a glass of pure water, are the celery cells hypertonic, hypotonic or isotonic compared to the water? In which direction will water move? 5.What is the water potential of pure water? 6.Why don’t red blood cells swell or shrink in blood plasma?Diffusion and Osmosis
