Movement of Materials in Cells

What is the definition of diffusion?

• Movement of water from a high concentration to a low concentration through a partially-permeable membrane
• Movement of molecules from a low concentration to a high concentration using energy
• Movement of molecules from a high concentration to a low concentration

How does osmosis differ from active transport?

• Osmosis moves molecules from a high to a low concentration
• Osmosis requires energy
• Osmosis moves through a membrane
• Osmosis moves water from a dilute to a concentrated solution

What is the difference between diffusion and osmosis?

• Diffusion is through a partially permeable membrane
• Osmosis is only water
• Osmosis moves from a high salt concentration to a low salt concentration

What is the definition of osmosis?

• Movement of water from a high concentration to a low concentration through a partially-permeable membrane
