Diffusion
|
The passive movement of molecules or particles along a concentration gradient, or from regions of higher to regions of lower concentration.
|
|
|
Facilitating diffusion
|
Transport of substances across a biological membrane from an area of higher concentration to an area of lower concentration by means of a carrier molecule. Since the substances move along the direction of their concentration gradients, energy is not required.
|
|
|
Aquaporin
|
plant cell wall polysaccharides containing predominantly arabinose and galactose.
|
|
|
Osmosis
|
Diffusion of a solvent (usually water molecules) through a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.

|
Isotonic
|
Having equal tension
|
|
|
Hypertonic
|
Having a greater degree of tone or tension.
|
|
|
Hypotonic
|
having a lesser degree of tone or tension, as in a ‘hypotonic muscle’.
|
|
|
osmotic pressure
|
A hydrostatic pressure caused by a difference in the amounts of solutes between solutions that are separated by a semi-permeable membrane.
