Detailed explanation-1: -“Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient.”

Detailed explanation-2: -Diffusion is a random movement of molecules down the pathway called the concentration gradient. Molecules are said to move down the concentration gradient because they move from a region of higher concentration to a region of lower concentration.

Detailed explanation-3: -Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.

Detailed explanation-4: -Down a Concentration Gradient refers to going from regions of high concentration of some entity to regions of low concentration, and such movement generally occurs spontaneously, that is, if allowed to happen it happens. Concentration gradients can be either gradual or instead abrupt.

Detailed explanation-5: -A diffusion gradient is a gradient in the rates of diffusion of multiple groups of molecules through a medium or substrate. The groups of molecules may constitute multiple substances, portions of the same substance that have different temperatures, or other differentiable groupings.
