Phagocytosis

Either A or B

None of the above

Detailed explanation-1: -The other type is pinocytosis (“cellular drinking”), which involves the ingestion of fluid and solutes via small pinocytic vesicles (about 100 nm in diameter). Most eucaryotic cells are continually ingesting fluid and solutes by pinocytosis; large particles are most efficiently ingested by specialized phagocytic cells.
Detailed explanation-2: -Is the ingestion of liquid into a cell by the budding of small vesicles from the cell membrane.
Detailed explanation-3: -Pinocytosis is the process whereby cells take in liquid material from their external environment; literally ‘cell drinking’. Liquid is enclosed in vesicles, formed by invagination of the plasma membrane. These vesicles then move into the cell and pass their contents to endosomes.
