It triggers diffusion because diffusion is the movement of molecules, therefore as soon as the molecules move diffusion begins to do it's job. It will take them from areas of greater concentration to areas of lesser concentration.
One way that substances enter a cell is through diffusion. Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration. When the molecules are even throughout a space it is called equilibrium.
diffusion Diffusion The tendency of matter to spread to areas of lower concentration is called diffusion if referring to the solute. It is called osmosis if referring to the solvent. diffusion Diffusion osmosis! Diffusion. The particles move till they reach equilibrium.
passive does not use energy, active does. Active moves molecules from areas of low concentration to areas of high concentration, while passive moves molecules from areas of low concentration to areas of high concentration.
