Final answer:
Phagocytosis is the process of engulfing large particles like food, and pinocytosis is the process of engulfing liquids. Both are types of endocytosis, a form of active transport into a cell.
Step-by-step explanation:
The bulk transport of large materials for example some kind of food particles into the cell is called as phagocytosis, while the bulk transport of liquids into the cell is referred to as pinocytosis. Both processes are forms of endocytosis, which is a type of active transport that moves substances, including fluids and particles, into a cell. This process involves the cell membrane forming a pocket around the substance that needs to be transported, and then pinching off to form an internal vesicle within the cytoplasm containing the ingested substance.
