  • Passive Transport By Aaron Burks
  • What is Passive Transport? Passive transport is a movement of ions and other atomic or molecular substances across cell membranes without need of energy input. 
  • Diffusion is when substances move from an area of high concentration to an area of low concentration, until the concentration becomes equal throughout a space.
  • Osmosis a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane.
  • Facilitated diffusion is the process of spontaneous passive transport of molecules or ions across a biological membrane via specific trans membrane integral proteins.
