Diffusion and it does not have to be through a semi permeable membrane.
Concentration Gradient.. :)
The chemical gradient refers to the imbalance of substances across the membrane. The Electrical Gradient refers to the difference of charges between substances on different sides of the Membrane. The Electrochemical Gradient refers to the combination of the previous two gradients. The short answer is MEMBRANE POTENTIAL.
resting membrane potential
the cell membrane is the outer living cell covering the cell wall is over the cellmembrane
