Vedclass · Answer

(A) Pinocytosis (cell drinking) and phagocytosis (cell eating) are types of endocytosis.These processes involve the invagination of the plasma membrane to engulf extracellular materials.In prokaryotic cells,the presence of a rigid cell wall and the lack of a complex endomembrane system (such as vesicles and lysosomes) prevent these processes from occurring.Therefore,pinocytosis and phagocytosis are absent in prokaryotic cells.
