Detailed explanation-1: -Active transport methods require the direct use of ATP to fuel the transport. Large particles, such as macromolecules, parts of cells, or whole cells, can be engulfed by other cells in a process called phagocytosis.

Detailed explanation-2: -Phagocytosis is a type of endocytosis, which is when cells ingest molecules via active transport as opposed to molecules passively diffusing through a cell membrane.

Detailed explanation-3: -In contrast, phagocytosis, receptor mediated endocytosis, and active transport are all active processes and require expenditure of cellular energy.

Detailed explanation-4: -Endocytosis is the process of capturing a substance or particle from outside the cell by engulfing it with the cell membrane, and bringing it into the cell. Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell.
