What is the best definition of diffusion? random movement of molecules across a concentration gradient until the difference in concentration between two regions is near zero a process in which molecules move across a semipermeable membrane until the number of molecules of water is nearly equal on both sides net movement of molecules across a permeable membrane bilayer that requires transport proteins the exchange of solute molecules across a permeable membrane from areas of high concentration to areas of low concentration
