How is osmosis different from diffusion?

1 Answer


In osmosis liquid cross the bio-membrane, while diffusion of gases is bio-membrane free event.


  1. The liquid moves from the hypertonic solution to hypotonic solution by crossing the semipermeable bio-membrane. It is a selective event.
  2. Diffusuion is a movement of the gases from the higher concentration to the lower concentration without crossing any type of bio-membrane.
