How does amoeba obtain its food?

उत्तर
Amoeba obtains their food by the process of endocytosis. Endocytosis refers to the invagination of a small region of the plasma membrane to engulf the food particle and ultimately form an intracellular membrane-bound vesicle.
Depending upon the type of food material, endocytosis may be (i) phagocytosis (intake of solid material) or (ii) pinocytosis (intake of liquid material).
Phagocytosis is a common method of feeding in some protozoans e.g., Amoeba. In this method, a part of the plasma membrane invaginates in the region of solid food particles and engulfs it. The membrane-enclosed vesicle called phagosome containing the food particle detaches from the plasma membrane into the cytoplasm, where its contents are digested by lysosomal enzymes.
