Dissolved substances have to pass through the cell membrane to get into or
out of a cell. Diffusion is one of the processes that allows this to happen.
Diffusion occurs when particles spread. They move from a region where they
are in high concentration to a region where they are in low concentration.
Diffusion happens when the particles are free to move. This is true in gases
and for particles dissolved in solutions. Particles diffuse down a
concentration gradient, from an area of high concentration to an area of low
concentration. This is how the smell of cooking travels around the house
from the kitchen.
