The movement does not require energy. In facilitated diffusion, a molecule is transported across a membrane with the help of a carrier protein. Diffusion is a process of passive transport in which molecules move from an area of higher concentration to one of lower concentration. Diffusion Process:- The movement of molecules or ions of a solid liquid or gas from the region of their higher concentration to the region of their lower concentration is called diffusion. Diffusion Diffusion is a passive process of transport.

ion diffusion across a semipermeable membrane Diffusion is the tendency of molecules to spread into an available space. This tendency is a result of the intrinsic thermal energy (heat) found in all molecules at temperatures above absolute zero.

The difference in the concentrations of the molecules in the two areas is called the concentration gradient. Diffusion will continue until this gradient has been eliminated. Diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. A familiar example is the perfume of a flower that quickly permeates the still air of a room. Both living and nonliving systems experience the process of diffusion.
Diffusion. Diffusion is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space. You are familiar with diffusion of substances through the air. Diffusion. Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration.

A simplified way to understand this concept is to imagine a crowded subway train in New York City. Diffusion -the process by which molecules spread from areas of high concentration, to areas of low concentration.
