Why is diffusion important for all living things?

Answer 1

Diffusion is the movement of molecules from an area where they are more concentrated to an area where they are less concentrated. In other words, diffusion occurs when concentrated molecules spread out and become more randomly distributed. Diffusion is important for all living things because it helps cells get materials they need, and get rid of wastes they don't need. If food is concentrated outside of cells, it can diffuse into cells. Water also diffuses in and out of cells depending upon the concentration of other molecules in the environment. The diffusion of ions is essentially for the proper functioning of nerve and muscle cells. Your body also relies upon diffusion to move oxygen from your lungs into your tissues, and in the processing of wastes in your kidneys. Basically, all living things rely upon the process of diffusion to move molecules from one place to another.
