Cell Membrane and Transport Quiz

What is the function of the cell membrane?

• To move things into the cell and out of the cell
• To provide structure to the cell

What is diffusion?

• The movement of molecules from an area of high concentration to an area of low concentration
• The movement of water across a membrane
• The movement of large molecules through the cell membrane

What happens during osmosis?

• Water moves from an area of low concentration to an area of high concentration
• Water moves from an area of high concentration to an area of low concentration
• Salt moves from an area of low concentration to an area of high concentration
• Salt moves from an area of high concentration to an area of low concentration
