Quizplus · Accepted Answer

Exocytosis is the process by which a vesicle fuses with the plasma membrane and releases its contents to the extracellular space. Endocytosis is the opposite process, where substances are taken into the cell by forming vesicles from the plasma membrane. Extracytosis and entrocytosis are not valid biological terms. Phagocytosis is a type of endocytosis where solid particles are engulfed by the cell.
