Pinocytosis occurs when the plasma membrane encloses small fluid droplets and takes them into the cell. This is a form of endocytosis, where materials are brought into the cell by the invagination of the plasma membrane. Active diffusion, facilitated diffusion, and phagocytosis do not involve the enclosure of small fluid droplets, and receptor-mediated exocytosis involves the release of materials from the cell rather than their uptake.
