Answer:

both

both are systems that move water nutrients into cells and remove waste

passive

movement of molecules DOWN the concentration gradient ( no cellular energy needed)

active transport

moves molecules through the cell membrane against the concentration gradient
disrupts the equal balance made by diffusion
