उत्तर
endocytosis
Explanation -
Endocytosis is the ingestion of food materials by the cells through the plasma membrane.
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.
