The difference between dialysis and diffusion is that A. dialysis involves the movement of water molecules. B. diffusion involves movement against the concentration gradient. C. dialysis involves passive movement through a cell membrane. D. diffusion is caused by a hydrostatic pressure difference.
Option C. Diffusion is passive and happens withinside the route of the concentra- tion gradient. Diffusion can arise inside an solution or throughout a membrane. Dialysis on the opposite hand, calls for a membrane and is a term implemented to sol- utes, now no longer water molecules.
