Detailed explanation-1: -Pinocytosis is an endocytosis process whereby extracellular fluids or particles (0.5 µm or smaller) are ingested by the cell. Briefly, cell membranes endocytose the external substances and collect them inside the membrane-bound vesicles, which are then transferred inside the cell.

Detailed explanation-2: -Pinocytosis is an active, energy consuming process where extracellular fluid and solutes are taken up into a cell via small vesicles. It is a type of endocytosis, which refers to the uptake of substances by a cell.

Detailed explanation-3: -Pinocytosis (cell drinking) describes the internalization of extracellular fluid and small macromolecules by means of small vesicles. Phagocytosis (cell eating) describes the ingestion of large particles such as cell debris and whole microorganisms by means of large vesicles.

Detailed explanation-4: -pinocytosis, a process by which liquid droplets are ingested by living cells. Pinocytosis is one type of endocytosis, the general process by which cells engulf external substances, gathering them into special membrane-bound vesicles contained within the cell.

Detailed explanation-5: -Cells in the kidney can use pinocytosis to separate nutrients and fluids from the urine that will be expelled from the body. In addition, human egg cells also use it to absorb nutrients prior to being fertilized.
