DIFFUSION : The net movement of particles from an area of high concentration to an area of low concentration.
NET MOVEMENT : This is only to an area of low concentration.
-Net movement continues until particles are evenly spread through liquid/gas.
CONCENTRATION GRADIENT : Path from area of high conc. to an area of low conc.
-Particles diffuse down a concentration gradient.
-Diffusion is a passive process (REQUIRES NO ENERGY)
SIMPLE DIFFUSION : When particles diffuse directly through a cell membrane.
