  • diffusion is the passive movement of particles
  • diffusion is the net movement of particles from an area of higher concentration to an area of lower concentration
  • molecules will diffuse both ways, but the overall movement will be to an area of lower concentration. continues until the particles are evenly distributed
  • a passive process - no energy is required
  • particles move directly through the membrane in simple diffusion
