CAN YOU EXPLAIN ME OSMOTIC PRESSURE IN DETAIL?
Asked by anmolsharmadp | 28th Jul, 2015, 07:39: PM
- Osmotic pressure is the minimum pressure that must be exerted to prevent the passage of the pure solvent into the solution when the two are separated by a semi-permeable membrane.
- It can also be defined as a measure of tendency of a solution to take in water by osmosis.
- Plant cells exhibit a considerable range of variations in osmotic pressure.
- In land plants, osmotic pressure varies from 5 to 30 atms, while in aquatic plants, it varies from 1 to 3 atms. Plants of arid regions possess the highest osmotic pressure.
Factors Affecting Osmotic Pressure
- Concentration of solute particles
- Ionisation of solute molecules
Importance of Osmotic Pressure in Plants
- Leaves become turgid and expand because of their osmotic pressure.
- Resistance of plants to drought and frost is brought about by osmotic pressure of their cells.

- what is turgor pressure
- the pressure responsible for the movement of water molecules across the cortical cells of the roots.
