Amoeba acquires its food through a process, termed
(a) exocytosis
(b) endocytosis
(c) plasmolysis
(d) exocytosis and endocytosis both
Answer : (b)
Amoeba obtains its food through the process of phagocytosis. It is a common way of feeding in protozoans. The amoeba’s plasma membrane forms a pocket around the food material and engulfs the solid material, forming a food vacuole in cytoplasm. The contents are digested by lysosomes which contain digestive enzymes.
Exocytosis is a form of active transport and bulk transport in which a cell transports molecule out of the cell by secreting them through an energy-dependent process.
Endocytosis is a cellular process in which substances are brought into the cell.
Therefore, option (b) is correct.
