Transcript
Do you understand the basic parts of the cell membrane? Can you model it? Objective: Become familiar with the structure and function of the cell membrane. Use modeling clay to construct a 3D model of cell membrane structures. Use color and labels to distinguish key elements (20 pts. – 10 for model and 10 for diagram and questions) Materials: Colored modeling clay Key elements that you should include: Phospholipids (polar head, non-polar tails) Integral proteins Peripheral proteins Glycoproteins (includes carbohydrates) Cholesterol Create a color coded key and diagram of your cell membrane system in the space below: Questions: Why is the cell membrane sometimes referred to as a fluid mosaic? What part of the membrane acts like a fluid and what part(s) make it a mosaic? How do the properties of a lipid help explain the structure of a cell membrane? Why do you think it is important cell membranes are selectively permeable?
