fills the region between the cell membrane and the nucleus
carries along the nucleus and other organelles
helps attached ribosomes make proteins
stores water, food, and other materials needed by the cell
Known as the cell's "Warehouse," this receives proteins and other newly formed materials from the ER, packages and distributes them to other parts of the cell.
