Detailed explanation-1: -Phagocytosis is a special form of endocytosis in which large particles such as microorganisms and dead cells are ingested via large endocytic vesicles called phagosomes.

Detailed explanation-2: -Phagocytosis is the process by which a cell engulfs and internalizes a large particle, such as a bacterium, by extending its membrane around it. Pinocytosis is similar, but instead the cell engulfs droplets of extracellular fluid, taking in any dissolved substances within.

Detailed explanation-3: -Amoebae typically ingest their food by phagocytosis, extending pseudopods to encircle and engulf live prey or particles of scavenged material. Pinocytosis the ingestion of liquid into a cell by the budding of small vesicles from the cell membrane.

Detailed explanation-4: -The term “endocytosis” was coined by Christian deDuve in 1963 to include both the ingestion of large particles (such as bacteria) and the uptake of fluids or macromolecules in small vesicles. The former of these activities is known as phagocytosis (cell eating) and the latter as pinocytosis (cell drinking).

Detailed explanation-5: -There are two types of endocytosis: phagocytosis and pinocytosis. Phagocytosis, also known as cell eating, is the process by which cells internalize large particles or cells, like damaged cells and bacteria.
