osmotic pressure

The pressure built up inside the cells as a result of the entry of water is called osmotic pressure. The entry of water into the cells is regulated by the solutes in the cell. Less concentration of solutes means more concentration of water. Positive osmotic h..

Osmotic pressure is the pressure required to prevent the net movement of pure water into a solution so as to prevent the volume of the solution from increasi..

The excess pressure that must be applied to the solution/conc.solution to prevent osmosis. fig 3.11 - Principle of measuring osmotic pressure fig 3.12 If two solutions of identical composition but different concentration are separated by a semi permeable membr..

Vant Hoff, analyzing the available data on osmotic pressure of solutions concluded that osmotic pressure of dilute solutions varied with their concentration and temperature in the same way as pressure of the gas. He enunciated some laws for solution..

Diagram showing relationship of Osmotic Pressure (OP), Turgor Pressure (TP) and Wall Pressure (WP) The actual pressure exerted by the protoplasm of turgid cell against cell wall is the turgor pressure..

The positive osmotic pressure developed inside a cell as a result of entry of water is called turgor pressure. When the cells are full of water, they are called turgid and when they lose water, they are called flaccid. The root cells become turgid after the absorption ..

The osmosis process can actually be reversed if a pressure larger than the osmotic pressure be applied to the solution. This phenomenon has found uses in water purification, especially the desalination of sea wate..

It is a process involving net diffusion of water molecules from a region of higher water concentration to a region of lower water concentration through a semipermeable membrane. The osmotic movement of water from a surrounding medium into a cell is called endosmosis. Such a medium is desc..

Cell walls in living organisms are seldom perfectly semipermeable. Usually they permit passage to some of the simpler substances and then these substances fail to register an osmotic pressure contribution on the cell walls. The reduced osmotic pressure of a s..
