A diffusion gradient, or concentration gradient, exists when an area of higher concentration is in contact with an area of lower concentration. When substances are in contact, particles may flow between them.he particles of a substance are in continuous, random motion in every direction, but there is a net flow of particles down the diffusion gradient or, in other words, from the area of higher concentration to the area of lower concentration.
Best Answer: Diffusion is: The passive movement of molecules or particles along a concentration gradient, or from regions of higher to regions of lower concentration.You could find the gradient by drawing a line from the area where there is the most of some molecule to the area where there the least.eport Abuse. Concentration gradient is the concentration of molecules between two regions. For example, when a drop of KMWO4 crystal was added to the water, the dye molecules move around and between the water molecules and eventually are spread evenly, even when not stirred.
