A cell can import and export large materials or large amounts of material in vesicles during the processes of endocytosis and exocytosis. Cells use energy to transport material in vesicles. Exocytosis is the process of expelling material from the cell. Download ppt "CHAPTER 3: CELL STRUCTURE & FUNCTION".
