Amoeba acquires its food through endocytosis. Endocytosis refers to invagination of a small region of the plasma membrane, and ultimately forming an intra-celllular membrane-bound vesicle. This process is generally involved for the ingestion of food material. Intake of liquid food using endocytosis is called pinocytosis or cell drinking. Similarly, intake of solid particles by a cell through its cell membrane is called phagocytosis or cell eating. In this process, cell membrane puts up protoplasmic processes around the food particle. The processes join, fuse to form phagosome.
