The correct option is A Prokaryotic cells
Pinocytosis (cell drinking) and phagocytosis (cell eating) are bulk transport mechanisms generally seen in animal and protist cells. The prokaryotic cells do not show pinocytosis and phagocytosis. These mechanisms are bulk transport mechanisms for transport of large quantities of micromolecules, macromolecules and food particles through the membrane. Thus, the correct answer is option A.
