Colligative properties are the physical changes that result from adding solute to a solvent. These depend on how many solute particles are present as well as the solvent amount, but they do not depend on the type of solute particles, although do depend on the type of solvent.Osmotic pressure is a colligative property of solutions that is observed using a semipermeable membrane, a barrier with pores small enough to allow solvent molecules to pass through but not solute molecules or ions Transport in lants,survival of cells, killing of snails and slugs swelling of resin are some examples where osmotic pressure seems applicable in real life situations.
