The difference in concentration between solutions on either side of a cell membrane is a concentration gradient.
In the field of biology, a concentration gradient can be described as a difference in the concentration of molecules inside and outside of a cell. It is due to concentration gradient that molecules move into and out of a cell through the cell membrane.
Some molecules move from an area of higher concentration gradient to an area of lower concentration along the concentration gradient. Diffusion is an example of such a process.
On the other hand, some molecules move from an area of lower concentration to an area of higher concentration against the concentration gradient. Active transport is an example of such a process.
