Wilhelm Friedrich Philipp Pfeffer (9 March – 31 January ) was a German botanist developed a semi-porous membrane to study the phenomena of osmosis. The eponymous "Pfeffer cell" is named for the osmometric device he. is a phenomenon of paramount significance for the transport of water and solutes through biological membranes. It accounts for fluid transport out of the kidney tubules and the gastrointestinal tract, into capillaries, and across.
Osmosis acts to equalize concentration on both sides of a membrane. Since the solute particles are incapable of crossing the membrane, its the water or other solvent that needs to move.
The closer the system gets to equilibrium, the more stable it becomes, so osmosis is thermodynamically favorable.
A good example of osmosis is seen when red blood cells are placed into fresh water. The cell membrane of the red blood cells is a semipermeable membrane.
The concentration of ions and other solute molecules is higher inside the cell than outside it, so water moves into the cell via osmosis.
This causes the cells to swell. Since the concentration cannot reach equilibrium, the amount of water that can move into the cell is moderated by the pressure of the cell membrane acting on the contents of the cell.
Often, the cell takes in more water than the membrane can sustain, causing the cell to burst. A related term is osmotic pressure.
Osmotic pressure is the external pressure that would need to be applied such that there would be no net movement of solvent across a membrane. Share Flipboard Email.
