Diffusion and Osmosis

What is the diffusion of water only across a cell or semi-permeable membrane?

• Osmosis
• Diffusion
• Active Transport
• Passive Transport

What type of cellular transport uses energy?

• Passive Transport
• Active Transport

In which case would a cell most likely shrink?

• when placed in a solution containing a high salt concentration
• when placed in a isotonic solution
• when placed in a solution containing a low pH
• when placed in a solution containing distilled water

A student noticed that placing wilted lettuce in a bowl of cool water caused the lettuce to become more crisp and firm. What is the best explanation for his observation?

• Water moved into the lettuce cells by active transport.
• Water moved into the lettuce cells by osmosis.
• Salt moved into the lettuce cells by diffusion.
• Water moved out of the lettuce cells by osmosis.
