Apart from gaseous exchange how is diffusion important for organisms

Dear student, Diffusion is an essential function in living organisms. Diffusion is the random but directional movement of molecules from a place of high concentration to a place of low concentration. It also describes how nerve cells are able to send electrical signals to each other cells. Diffusion tells embryonic cells where to crawl and when they have arrived. Diffusion also makes it possible to reduce the loss of body heat to the surrounding environment. With regards.
