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
  

The picture below is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport

Is this an example of Osmosis or Diffusion?

• Osmosis
• Diffusion
• Something else
• Neither

What is the definition of Equilibrium?

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