Final answer:
Phagocytosis is a type of endocytosis that allows a cell to engulf large particles, contrasting with pinocytosis and receptor-mediated endocytosis, which deal with fluid and specific substances, respectively.
Step-by-step explanation:
The type of large-scale endocytic process that can envelop large particles is phagocytosis. Phagocytosis is a non-selective form of endocytosis where the cell membrane surrounds and engulfs large particles such as macromolecules, parts of cells, or microorganisms, creating an intracellular vacuole.
This is different from pinocytosis, which involves the ingestion of liquid droplets, and receptor-mediated endocytosis, which is a selective form that targets specific substances recognized by cell-surface receptors.
