Diffusion vs. Osmosis What is the difference between diffusion
and osmosis? Processes of the forces of nature where atoms move
from an area of high concentration to an area of low
concentration are called diffusion and osmosis. These concepts
are very important ones in science and are taught in physics,
chemistry, and biology classes. Everything that happens in
nature is explained in terms of the movement of atoms and
molecules. Diffusion and osmosis describe these processes at a
microscopic level. Both diffusion and osmosis refer to the
movement of atoms and molecules, there are differences between
them. Diffusion refers to the movement of molecules from areas
of higher to lower concentration, but osmosis refers to the
movement of water only across a permeable membrane. This means
that it is only water that can go through osmosis and also means
that osmosis is a type of diffusion. An illustration of how this
process works in our bodies is how the salt draws water from the
cells when we eat salty food. Diffus
