Which statement is true for both pinocytosis and phagocytosis?

Both pinocytosis and phagocytosis involve movement of the plasma membrane. Pinocytosis is cell drinking, whereas phagocytosis is cell eating. Both events require the recruitment of actin and other cytoskeleton elements. Phagocytosis is not spontaneous and is selective, being triggered by specific receptor-ligand interactions and Endocytotic vesicles fuse with ribosomes that release hydrolases into the vesicles
