How does diffusion differ from osmosis?

Answer 1

Diffusion is simply the migration of a substance through a medium.

eg. If you put a drop of Iodine in a Becker of water it will slowly diffuse through the whole solution. This is an example of the second law of thermodynamics.

Osmosis requires a semi-permeable barrier that creates or allows a disparity in concentration on either side.

Osmosis and Diffusion:Remember that molecules tend to move from an area of higher concentration to an area of lower conventration. In osmosis, water molecules move by diffusion from an area where they are highly concentrated through tue cell membrane tp an area where they are highly concetranted through the cell membrane to an area where they are less concetrated.

Answer 2

Diffusion is the passive movement of molecules from an area of high concentration to low concentration, while osmosis specifically refers to the movement of water molecules across a semi-permeable membrane. Osmosis involves the movement of water to equalize solute concentrations on both sides of the membrane, while diffusion can occur with any type of molecule.

Answer 3

Osmosis is the diffusion of water through a water molecule of the cell wall, while diffusion is the movement of molecules from a area of high concentration to a area of low concentration.
