Detailed explanation-1: -Cell taking in some fluid by an infolding of the membrane is called as Pinocytosis.

Detailed explanation-2: -Endocytosis is the process of taking material into the cell by means of infoldings, or pockets, of the cell membrane.

Detailed explanation-3: -Phagocytosis is the process by which cells ingest large particles, including other cells, by enclosing the particles in an extension of the cell membrane and budding off a new vacuole.

Detailed explanation-4: -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-5: -Endocytosis is a process that takes materials into a cell through infoldings or pockets in the cell membrane. Endocytosis involves the formation of a vesicle as the cell membrane invaginates and “pinches off” into the cytoplasm.
