PLANT AND ANIMAL CELL PROJECT DUE: Wednesday Sept. 9th As we begin our studies over the structures and functions of plant and animal cells, it is important that you understand how cells work and do their job inside our bodies. To do this you will create a 3-D plant or animal cell. Objective: By making a 3-D model of the cell, the student will become aware of the various organelles and structures, which make up a plant or animal cell. Guidelines: You may choose to turn the project in early. If you decide to, you can receive up to 10 points extra credit on any test grade (Not to exceed a 100). Be sure to write which cell model you are making (Plant or animal) Project may NOT be edible at all due to critter problems arising. Thus, the model and all cell structures must be materials found in your house, not food. All parts of your cell must be labeled clearly in order to receive credit; I suggest using toothpicks and pieces of paper to make little flags. The cell should be as accurate as possible. The cell parts should be located where they belong. For example, the nucleus should be bigger than ribosome’s and chloroplast should be green. o Your cell must be 3-dimensional. This means it needs to have a front, back, and sides. It cannot be a piece of paper with things glued on it. Your plant cell must be rectangular or your animal cell must be circular. o Actual numbers of organelles found in real cells should be represented. Ex: Each cell has one nucleus. Plant cells have one large vacuole. Cells have multiple mitochondria and other organelles. Make sure to keep this packet in a safe place. It will need to be turned in when you turn in your cell to use the rubric to grade the project. Good luck and enjoy your adventure to discover the functions and structures of plants and animals cells. If the model is an ANIMAL CELL it must contain the following organelles: Materials you may want to If the model is a PLANT CELL it must contain the following organelles: use: 1. cell membrane 1. cell wall 2. nucleus SUGGESTIONS: 2. cell membrane Make sure your 3. nucleolus 3. nucleus organelles are 4. nucleolus secure before you 5. nuclear membrane move it.
