Pinocytotic vesicle is a membrane-bound vacuole formed by a specific type of endocytosis called pinocytosis. It stores water for the animal cell.
It is formed by a specific type of endocytosis called pinocytosis. The plasma membrane invaginates (pinches inwardly) to form a vesicle that detaches and moves into the cytoplasm. Macromolecular droplets and particles up to 2 micrometers in diameter enter the cell within these pinocytotic vesicles.
Larger particles (including bacteria) enter special white blood cells (phagocytes) through a form of endocytosis called phagocytosis. The Amoeba is a unicellular protist that ingests food (including algal cells) by phagocytosis.
