Osmosis

• diffusion of water molecules through a semi-permeable mebrane from an area of low concentration to an area of high concentration
• the diffusion of particles from an area of high concentration to an area of low concentration
• diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration
• the diffusion of particles from an area of low concentration to an area of high concentration

Equilibrium?

• a large  amount of substance on  side of the cell and a small amount on the other side
• a small  amount of substance on  side of the cell and a large amount on the otherside
• equal amount of substance on either side of the membrane  
• no particles on either side of the a cell membrane
