2Cells are Living Systems Welcome to the World of Cells!Introduction to Cells (2:55) Frank GregorioCells are tiny systems that make up all living things, including YOU!Tiny parts called organelles work together in this system to make proteins. This is a cell’s main job!Proteins are important products that give you observable traits like hair, eye, and skin color.We can compare our cell system to an everyday system we are familiar with: a Keebler Cookie Factory. You will be surprised at how similar the two really are!Cells are Living Systems
3Both Systems Make A Final Product CellsKeebler FactoryOur factory can make a variety of cookies.Our cells can make a variety of proteins.antibodykeratinhemoglobin

Predict the function of each cell part by using what you know about the Keebler Factory parts. Write small notations in the labeled column.
5Factories Need a Boss Keebler Factory Cell Ernie Elf He controls everything that happens inside the factory.Ma KeeblerInside Ernie’s office, trains elf workers.NucleusIt controls everything that happens inside the cell.Nucleolusinside nucleus, makes ribosome workers.nucleolus
6Factories Need Instructions Keebler FactoryCellRecipesThe instructions for making delicious cookies.DNA (chromatin)The instructions for making important proteins.
7Factories Need Workers CellKeebler FactoryElvesThey read the recipes and make cookies.They work along the assembly line or on the factory floor.RibosomesThey read the DNA and make proteins.Found on ER or floating in cytoplasm.
8Factories Need To Move Their Product Keebler FactoryCellCookie Assembly LineA large conveyor belt that moves cookies to their next location.Endoplasmic Reticulum (ER)A maze of membranes that moves proteins to their next location.
9Factories Need to Pack & Ship Keebler FactoryCellPacking/Shipping DepartmentFast Eddie packs the cookies into boxes, tags them with a tracking label, and ships them to stores to be sold or in warehouse storage.Golgi BodyIt packages, tags, and ships the proteins out of the cell or to storage.
10Factories Need Vehicles Keebler FactoryCellKeebler Factory CarsThese carry the cookies from one part of the factory to the other.VesiclesCarries the proteins from one part of the cell to the other. (sounds like “vehicle”)
11Factories Need Storage Keebler FactoryCellCookie WarehouseCookies can be stored in this room along with other raw materials until needed.VacuoleStores proteins along with food and water until needed.
12Group Activity! – Map the Path of our Product Keebler FactoryCell1. Take the six picture cards provided by your teacher and place them in the correct order to show the path a cookie takes through the Keebler factory. 2. Now create a caption for each card using six post-it notes. Stick the post-it next to the card.3. Do the same process for the cell using the six picture cards and six NEW post-it notes.THINK! – If you remove one of the pictures in our chain, is the cell still alive? Why or why not?
13Factories Need Protection Keebler FactoryCellFactory DoorIt regulates what can enter and exit the factory.Cell MembraneIt regulates what can enter and exit the cell.
14Factories Need Space Keebler Factory Cell Factory Floor Cytoplasm It holds all the other parts of the factory in place.CytoplasmIt holds all the other cell parts in place. It’s like Jell-O.
15Factories Need Power Keebler Factory Cell Generators They create energy so that the factory can power its baking machines.MitochondriaThese “mighty” organelles break down glucose (sugar) to create energy which powers the cell.
16Factories Need to Stay Clean Keebler FactoryCellClean-Up CrewThey clean the factory by removing waste, dirt, and debris from the factory floor.LysosomesThey clean the cell using powerful chemicals to digest waste, old cell parts, and foreign invaders.

19Visualization – The Inner Life of a Cell is Spectacular! Now that you know a cell’s job is to make proteins, watch these proteins in action as they work to make the inner life of a cell come alive.Harvard University selected XVIVO to develop an animation that would take their biology students on a journey through the microscopic world of cells.ABC Report- Inner Life of Cell
