A company could have individual employees make the entire products themselves, but it's more efficient to use an assembly line. Similarly, eukaryotic cells have specialized structures that perform specific tasks, much like the separate stages of an assembly line in a factory.
The Nucleus
Just as a factory needs a manager, a cell needs an organelle to direct the cell processes. The nucleus is the cell's managing structure. The nucleus contains most of the cell's DNA, which stores information used to make proteins for cell growth, function, and reproduction. Within the nucleus is the site of ribosome production, call the nucleolus.
