CELL TRANSPORT
Active transport is the process of moving molecules against the concentration gradient while Passive transport refers to the movement of molecules down the gradient. While in active transport transportation occurs from a low concentrated solute to high concentrated solute in the passive transport it occurs from high to low concentration.
