What is Diffusion in Biology?

simple diffusion  Simple diffusion is the process in which solutes are passed through the concentration gradient in a solution across a semipermeable membrane  Transmembrane Proteins Facilitated diffusion is a type of passive transport in which substances move across the cell membrane through helper proteins Because

Passive Diffusion, Simple Diffusion, Facilitated Diffusion! What is the Simple diffusion allows the direct transport of molecules across the cell membrane In contrast, facilitated diffusion occurs via transmembrane
