Passive Transport

Which of the following is a job of the cell membrane?

• Regulates which materials enter and leave the cell.
• Breaks apart lipids, carbohydrates, and proteins from foods.
• Stores water, salt, proteins, and carbohydrates.
• Keeps the cell wall in place.

What is the definition of  Selective Permeability?

• The movement of materials across the cell membrane that requires NO ENERGY from the cell.
  
• The movement of materials through (or across) the cell membrane
  
• The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.
• The movement of molecules from an area of high concentration (where the molecules are more crowded together) to a area of low concentration (where molecules are more spread apart)

Which way will the water molecules move during osmosis?

• Out of the cell, so the cell shrinks.
• Out of the cell, so the cell swells.
