You will have to argue that without your organelle, the cell and the organism and consequently the world as we know it will collapse. I expect you to understand the details of your organelles. Here’s what you have to do: • _You will put up campaign posters and other paraphernalia (with pre-approved permission of the classroom instructor) in the classroom. I am requiring at least one poster championing the greatness of your organelle. I suggest more than one poster if you want to win. This should be very visual, think of the iconic Obama Hope poster. • _In addition to your poster, you need to create a campaign flyer that describes how totally awesome your organelle is. Include a catchy graphic on the front, then details as to the structure of the organelle and the function of the organelle. Be sure to relate the structure of the organelle to its function. It is crucial for you to make the connection for your voter about why your organelle is the most important. So tell your voter why your organelle is important for survival of the organism. Can you link that to survival of an ecosystem? The whole entire world? Okay, maybe I’m being dramatic, but that is how campaigns can be! Get into this. Make sure you have references for this pamphlet! APA style for the references only. Use any formatting style you think looks groovy. Other than what I requested, go to town with the pamphlet. Quotes of doctors or other experts? Sounds great. Pictures? Perfect. • _Mudslinging. The fun stuff. You need to run a smear campaign against at least 5 other organelles. Look up what diseases are associated with mutations or malfunctions of their organelles and create some kind of literature against it (poster, pamphlet, fact sheet, T shirt, radio ad, etc) and you have to include it in your campaign speech. You must have a smear campaign against EACH of the 5 other organelles. • _Election Day: Campaign speeches - Please choose one person from the group to perform the speech. You will be performing your speech to the class you have been passing out the pamphlets and posting the posters for. Some of these speeches will also be videotaped. In your speech, you need to convince the voters based on structure and function that your organelle is the most important. You have to try to deflect the smear campaigns that have hit you. Limit the speeches to 5 minutes. I will get the giant hook and remove you from the stage. Your group will provide me with a transcript of the speech on the same day, complete with references in APA formatting. After the speeches, the students will complete a ballot. The number of votes you get is part of your grade, albeit a smaller percentage. In order to avoid everybody voting for their own and nobody winning, you will be required to vote for your own organelle as well as one other. Beyond what I have required, you can be as creative as is ethically correct to win this campaign. No threatening or bribing other students, please. But extra posters, T shirts, buttons, stickers, pencils, face paint...I don’t know. You come up with the ideas! If you need copies made, I can help, but they will only be in black and white. Good Luck! List of organelles: Nucleus (including nucleolus, chromosomes, chromatin, and nuclear membrane) Ribosome Smooth and Rough endoplasmic reticulum Cytoskeleton (including cilia, flagella, and centrioles) Mitochondria Chloroplast Golgi body Peroxisomes Lysosomes Cell Wall Plasma Membrane (Cell Membrane) Vacuole (including both animal cell and plant cell vacuoles) Intercellular Junctions (plasmodesmata, tight junctions, and gap junctions) Name_________________________ Period_________ The Cell Theory Students of biology take for granted knowledge that has been obtained by previous biologists. True, biology (or the study of living things) is one of the oldest if not THE oldest of the sciences. It probably had its beginning when ancient man recognized death for the first time. Ever since then, men have searched for the qualities they call “life.” The development of theories which most people know of today was a long and painful process. The knowledge we have today was not always known. It had to be learned piece by piece, and the knowledge we have today does not represent all the knowledge left that has yet to be discovered. Since cells cannot be seen with the naked eye, scientists did not know that cells existed until after the development of the microscope. Anton Van Leeuwenhoek (1632-1723) was a Dutch scientist and the first person to record seeing living organisms, which were too small to be seen by the naked eye, under his microscope. About the same time, in 1665, an Englishman named Robert Hooke, examined a plant tissue called cork with a crude microscope. He reported that this tissue all seemed to be made up of compartments. He called these compartments “cella,” the Latin word for small room, and this translates into English as “cell.” So Robert Hooke was the first person to use the word “cell” in describing the structure of living organisms. What Hooke called a cell was merely an empty “box,” completely devoid of living matter. However, observers soon realized that sometimes there was a light gray sap in those boxes. Sometimes they noticed a darker, denser, globule floating about in the sap. This globule caught the attention of the Scotch biologist, Robert Brown. His studies of tissues of orchid plants led him to conclude that the dark globule was a regular and important feature of all living cells. He announced his view in 1831, using the word “nucleus” to describe the structure. (The word “nucleus” is Latin for “little nut.”) The sap of the cell came in for its share of attention, too. In 1835 Felix Dujardin described it as the essential substance of life. In 1839 a Czech anatomist and physiologist, Johannes Purkinje invented the term “protoplasm” to describe the developing embryonic material in an egg. Soon the name was being applied to the living sap of the cell. In 1839 the cell theory, as it came to be called, was first announced to the world by two scientists working independently of each other. Matthias Schleiden and Theodor Schwann concluded that all living things were composed of cells. This was the first statement of the cell theory. Twenty years later, Max Schultz, a German anatomist, pointed out that the protoplasm was the physical basis of life. Now the cell theory was expanded to include another idea. Not only was the cell the unit of structure of a living thing, but it was the unit of function as well. In other words, living things functioned the way they did because their cells contained a living substance (protoplasm) having the properties of life. In 1855 Rudolf Virchow added the second important part of the cell theory. He stated that all cells could only come from other cells. At this point then, the cell theory can be summarized in three parts: 1. All living things are made up of cells. 2. Cells are the basic unit of function of all living things. 3. All cells can only come from pre-existing cells.

Name:_____________________________________ ______ Cell City Analogy In a far away city called Grant City, the main export and production product is the steel widget. Everyone in the town has something to do with steel widget making and the entire town is designed to build and export widgets. The town hall has the instructions for widget making, widgets come in all shapes and sizes and any citizen of Grant can get the instructions and begin making their own widgets. Widgets are generally produced in small shops around the city, these small shops can be built by the carpenter's union (whose headquarters are in town hall). After the widget is constructed, they are placed on special carts which can deliver the widget anywhere in the city. In order for a widget to be exported, the carts take the widget to the postal office, where the widgets are packaged and labeled for export. Sometimes widgets don't turn out right, and the "rejects" are sent to the scrap yard where they are broken down for parts or destroyed altogether. The town powers the widget shops and carts from a hydraulic dam that is in the city. The entire city is enclosed by a large wooden fence, only the postal trucks (and citizens with proper passports) are allowed outside the city. Match the parts of the city (underlined) with the parts of the cell. 1. Mitochondria ___________________________________________ ____ 2. Ribosomes ___________________________________________ _____ 3.
