The process in which a portion of the cell membrane folds inward to surround and bring molecules into the cell is called endocytosis. During this process, the membrane invaginates and forms a vesicle that encapsulates the molecules, allowing them to enter the cytoplasm. There are different types of endocytosis, including phagocytosis for larger particles and pinocytosis for fluids.
