Quizplus · Accepted Answer

Pinocytosis is the active process of transporting extracellular fluid, such as water and small molecules, across a plasma membrane. It involves the formation of small vesicles from the plasma membrane that enclose small amounts of extracellular fluid, which are then transported into the cell. Phagocytosis involves the engulfment of large particles, osmosis refers to the passive diffusion of water across a membrane, and diffusion refers to the passive movement of molecules from an area of higher concentration to an area of lower concentration.
