Answer:
Phagocytosis
Step-by-step explanation:
The process by which the cell takes large particles inside itself is called phagocytosis. Phagocytosis is a type of endocytosis, the general process for taking large molecules into the cell.
Phagocytosis is performed only by some specific cells, such as the cells of the immune system, where they engulf and destroy pathogens.
The cell membrane is flexible and fluid, and when it encounters a large particle or cell it would like to engulf, it contacts the particle and creates a pocket, which eventually encloses the membrane.
The particle is then enclosed in a compartment in the cytoplasm called a phagosome, and is protected from the rest of the cell contents. From here, the cell can break down the products in the phagosome.
