Detailed explanation-1: -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-2: -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-3: -Pinocytosis, also known as cell drinking, is common in plant and animal cells. During pinocytosis, the cell takes in substances from the extracellular fluid that it needs to function. These include things like water and nutrients.
Detailed explanation-4: -Phagocytosis. Phagocytosis (literally, “cell eating”) is a form of endocytosis in which large particles, such as cells or cellular debris, are transported into the cell.
Detailed explanation-5: -Pinocytosis is an endocytosis process whereby extracellular fluids or particles (0.5 µm or smaller) are ingested by the cell. Briefly, cell membranes endocytose the external substances and collect them inside the membrane-bound vesicles, which are then transferred inside the cell.
