Mr. Keser – 7/8 Science – Cell Model Project Projects Cell Model Project Purpose: To make a model of the cell using common everyday materials. Requirements: 1. Model: A model of an animal or plant cell will be made and the following organelles (where appropriate) will be labeled. Cell Membrane Cytoplasm Nucleus Cell Wall Nucleolus Nuclear Envelope Golgi Body Vacuole Smooth Endoplasmic Reticulum Rough Endoplasmic Reticulum Ribosome Mitochondria Lysosome Chloroplast Centriole 2. Labeling: The cell type (plant or animal) should be labeled. All cell organelles should also be labeled. Identification of organelles should be done using flags made of toothpicks stuck in the appropriate organelle. The name of the structure can be written on the flag or a number can be used which corresponds to a key of the structures. 3. Function Key: You must include a key for your model. The organelles should be listed and identified by the flags on your model. You should also include a brief explanation of the function of each organelle. 4. Cross Section of Cell Membrane: A second, smaller model of a cross section of a cell membrane will be made. You must show the phospholipid bilayer and the three types of cellular proteins. Be sure to label these and include them on your function key. Other Information Getting started: Decide if you want to make an animal or plant cell for your model Think of materials that would best represent the different organelles Make a key of the organelles and their functions before you make the model Materials used to represent organelles may include anything. I suggest that you use what you have at home. Do not make this into an expensive project! Ex: wood, buttons, yarn, thread, plastic, paper, Styrofoam, etc. Grading Correctly labeling organelles 2 points each Correct functions of organelles on key 2 points each Model of cell membrane cross section 10 points Correctly indicating plant or animal cell 3 points Total 73 points
