The movement of water molecules from an area of high concentration to an area of low concentration through a partially permeable membrane. 1 of 6 What is a partially permeable membrane? A membrane that contains small holes only allowing small molecules like water through 2 of 6 Why can water molecules pass both ways in osmosis? They are always moving randomly 3 of 6 Is there a steady flow of net movement? Yes, of water molecules into the area with fewer water molecules (stronger sugar solution) 4 of 6 What happens to the stronger solution? It becomes more dilute as the concentration is trying to balance 5 of 6 What is osmosis a type of? Diffusion 6 of 6
