When there are different amounts of a substance on either side of the cell membrane what gradient results.?
It is known as a concentration gradient which in diffusion will always flow from areas of high concentration to areas of lower concentrations.

When is a substance most likely to diffuse into a cell?
If there is the concentration of substance inside the cell is lesser than outside and cell membrane is permeable to the substance.
