 * Week of December 01st thru 05th:**

The purpose of this project is to reinforce your understanding of the structure of the cell; and, to associate the structure of your model to represent some basic organelles/parts along with their functions. Below are guidelines to help you create a model of a plant or animal cell. The cell parts must be well-crafted, colorful and neat. There must be at least ten (10) structural parts (organelles), which would include the cell membrane and the cell wall.


 * 1) The base of the model should be cardboard or Styrofoam, a stiff material; no poster board. Its dimensions must be between 8" x 10" and 10" x 12". __**10 points.**__
 * 2) Organelles must be fixed to the base so they do not fall off or become loose when touched or when the project is moved. __**20 points.**__
 * 3) Organelles must be labeled, to identify each part. __**10 points.**__
 * 4) Organelles must be crafted or made to have their own distinctive characteristic (appearance). __**20 points.**__
 * 5) Creativity and Color: Creativity involves the materials that are used to make or craft each organelle. (Think of the model shown to you in class.) The coloring of the different organelles must be of pre-colored material and/or colored by makers or colored pencils. __**15 points**__.
 * 6) Neatness: A tidy project is one that does not have the adhesive/glue that is used to keep the organelles in place, seen throughout the project either on the floor of the project or on other parts. The glue should dry clear and located only on the bottom of the organelles (parts) to keep them in place. __**15 points.**__
 * 7) The names of the organelles and their functions must be typed. After each name and function, double-space before typing the next organelle and function. Paper's title should be - Plant Cell: Parts and their Functions or Animal Cell: Parts and their Functions. __**10 points**__.

The total possible points for each criterion depend on you.
