Definition of diffusion gcse. Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. Diffusion is the net movement of a substance from an area of high concentration to an area of low concentration. Down the concentration gradient. Diffusion is the random movement of a substance from a region of high concentration to a region of low concentration ie.
Distance a shorter distance will increase the rate of diffusion. Why is diffusion of a gas through air slow. The cell is surrounded by a. Diffusion is the movement of molecules from a region of its higher concentration to a region of its lower concentration.
For living cells the principle of the movement down a concentration gradient is the same but there is one problem. Diffusion happens in liquids and gases because their particles move randomly from place. Diffusion is the random movement of one liquid or gas through another from a region of high concentration to a region of low concentration. Molecules move down a concentration gradient as a result of their random movement.
