What is the definition of Osmosis?

• the movement of WATER molecules across the cell membrane.
  
• the state where molecules are equally concentrated (balanced) on both sides of the cell membrane.
  
• the process that brings LARGE particles INTO the cell through the cell membrane
  
• he movement of molecules across the cell membrane that REQUIRES ENERGY output from the cell
  

Which cell structure allows molecules to enter and leave the cell? 

• Cell Membrane
• Nucleus
• Mitochondria
• Cytoplasm
