How does osmosis work?

1 Answer

Osmosis is the diffusion of water through a semipermeable membrane from an area of high concentration to an area of lower concentration.


Osmosis refers to the transport of water into or out of cells. Osmosis can occur directly through the membrane of the cell, or through transport proteins called aquaporin.

Here is a video which describes how osmosis impacts onion cells placed into tap water and then into a salt water solution.
