Can cell walls do phagocytosis
WebStep 3: Ingestion/Engulfment. Attachment/binding allows for identification and ingestion of the bacteria. During ingestion, the cell membrane of the phagocyte invaginates while surrounding the bacteria and engulfs it. This process results in the bacteria being enclosed in a vesicle/phagosome within the phagocyte. Phagocytosis (from Ancient Greek φαγεῖν (phagein) 'to eat', and κύτος (kytos) 'cell') is the process by which a cell uses its plasma membrane to engulf a large particle (≥ 0.5 μm), giving rise to an internal compartment called the phagosome. It is one type of endocytosis. A cell that performs phagocytosis is called a phagocyte.

Protozoa are the animal-like protists. These unicellular eukaryotes lack cell walls. They are heterotrophic and feed on other microorganisms or on organic particles. Protozoa ingest their food in two ways. The first is a process called phagocytosis, in which a flexible portion of the cell membrane surrounds a food particle and engulfs ...
