Detailed explanation-1: -High concentration means the amount of solute is high in the solution and low concentration means it is low. Amount of solvent is high in low concentration and low in high concentration of solute.
Detailed explanation-2: -A concentration gradient occurs when the concentration of particles is higher in one area than another. In passive transport, particles will diffuse down a concentration gradient, from areas of higher concentration to areas of lower concentration, until they are evenly spaced.
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: -“Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient.”
