- The driving force for the osmotic pressure is the higher concentration of sodium ions in the beads than in the outside water.
- The glucose osmotic pressure in solution with water is proportional to the glucose concentration in the outer solution.
- The solution also creates a strong osmotic pressure on the cell walls of bacteria and other micro-organisms, which prevents them from passing substances in or out.
