Daily Life Applications Of Osmosis:
Biochemists use a technique called haemolysis to study the contents of Red Blood Corpuscles. RBCs are protected from the external environment by a semi permeable membrane. Cells are placed in a hypotonic solution. Since hypotonic solution is less concentrated than the interior of the cell, water moves into the cells. The cells swell and eventually cytolyzes releasing haemoglobin and other molecules.

Osmosis is also the major mechanism for transporting water upward in plants. Leaves constantly loose water to the air by a process called transpiration. As a result, leaf fluids become more concentrated than the ground water. Thus water enters membranes in the roots and rises into the trees. It creates an osmotic pressure that can exceed 20 atm in the tallest trees.

A large quantity of sugaris essential to preserve jam and jelly. This is because the sugar helps to kill bacteria that may cause botulism. When a bacterial cell is placed in a hypertonic solution, the intracellular water tends to move outwards to the more concentrated sugar solution by osmosis. This causes the bacterial cell to shrink and cease functioning.

Food is preserved by coating with salt (NaCl) which produces a hypertonic solution. This food coated with salt causes microbes on the surface to shrivel and die from loss of cell water.
