Answer;

-Phagocytosis: endocytosis of large solid particles (“cell eating”)

-Pinocytosis: endocytosis of extracellular fluid that contains dissolved solutes (“cell drinking”)

-Receptor-mediated: highly selective, ligands bind to specific receptor proteins on the plasma membrane and are then taken into the cell

-Exocytosis: the reverse of endocytosis: substances are removed from the cell; vesicles fuse with plasma membrane and release their contents into the extracellular fluid; important in nerve cells to release neurotransmitter and secretory cells to release cell products (ex. digestive enzymes, protein hormones).
