Why is diffusion important for multicellular organisms?

The same reason it's vital for unicellular organisms: the movement of solutes for no energy cost. Cell membranes are semi-permeable, and the channels that allow the movement of most solutes are controllable for almost no energy. read more

Osmosis is important to maintain the water content in the cells. It is the vital mechanism in the transport of fluids in the living organisms. read more

diffusion there would be no respiration of the cells which is the central process in all the biological systems, thus we can say safely state that it is probably the most important process for organisms as without it, there would be no chance of survival whatsoever. read more
