Passive Transport - Osmosis

Posted by Cikgu Jes | 10:24 PM | 1 comments »

What is Osmosis?

Osmosis is the diffusion of a water through a semi-permeable membrane, from a solution of low solute concentration to a solution with high solute concentration.

It is a physical process in which a solvent moves, without input of energy, across a semi-permeable membrane separating two solutions of different concentrations.

Important Points:
  • It is the diffusion of water (normally) through a semi-permeable membrane.
  • It is from a dilute solution to a more concentrated solution.
