Which process does not belong with the others active transport or dialysis or phagocytosis or pinocytosis?

Dialysis does not belong with the others because it is a passive process that involves the movement of solutes across a semipermeable membrane due to concentration gradients, while active transport, phagocytosis, and pinocytosis are all active processes that require energy to move substances across cell membranes. Active transport moves ions or molecules against their concentration gradient, while phagocytosis and pinocytosis are types of endocytosis that involve the uptake of larger particles or fluids, respectively.
