A concentration gradient (difference in solute concentrations) is necessary for diffusion to occur. A cell membrane and membrane proteins may facilitate the process, but they are not required for diffusion to take place. Energy is not necessary for diffusion because it is a passive process where solutes move from high to low concentration without the need for an energy source.
