Pinocytosis can be recognized when the CELL IS ENGULFING EXTRACELLULAR FLUID
Explanation:
Pinocytosis is the process whereby the cell takes in macromolecules such as bacteria and antigens in form of fluid from the extracellular fluid.
The macromolecules in the form of droplets of fluid bind to the outer surface of the cell
The cell membrane enviginates around the droplets of fluid and are engulfed by the cell.
They form vacuoles with the macromolecules and are transported into the inner of the cell.
The formed structure is called ENDOSOMES which lysozomes combine with and form secondary endosomes containing enzymes to break down the macromolecules.
Pinocytosis is also called CELL DRINKING.
