SSC MTS EXAM

Detailed explanation-1: -Diffusion is the passive movement of molecules or particles from an area of higher concentration to an area of lower concentration. The concentration gradient incites them to diffuse.

Detailed explanation-2: -Passive transport describes the movement of substances down a concentration gradient and does not require energy consumption. Diffusion is the net movement of substances from an area of higher concentration to an area of lower concentration.

Detailed explanation-3: -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.
