12/10/09 To understand the functions carried on by the different parts of the cell, you must first understand why these parts are even needed. The easiest analogy is to compare a cell to a factory. THE PRODUCT OF THE CELL IS A PROTEIN. Proteins are vital to life - all cells must produce them 1 12/10/09 The Cell Organelles The Factory Counterparts 1. nucleus 1. The central office 2. ribosomes 2. Assembly line workers 3. endoplasmic reticulum 3. Internal transport 4. Golgi apparatus 4. Packaging 5. vesicle 5. Shipping 6. mitochondria 6. Generator (energy supply) 7. vacuole 7. Storage 8. lysosome 8. Recycling center 9. proteins found in cell 9. Doors into the membrane building 10 cell membrane and/or 10. Building cell wall 2 12/10/09 Rough ER! Chromatin! Nucleolus!
