Osmotic pressure

Definition

noun

A hydrostatic pressure caused by a difference in the amounts of solutes between solutions that are separated by a semi-permeable membrane.


Supplement

Osmotic pressure reduces water potential, which is the tendency of water moving from one area to another. Thus, it is necessary in plant cells for turgidity and support.


See also: hydrostatic pressure, Osmotic Potential, osmosis.
