CELL MEMBRANE Illustrate and label a detailed drawing of the cell membrane. Explain the role of each of the following in the membrane... c) Glycoproteins a) unsaturated fatty acids b) cholesterol List and explain the important role of the six major types of membrane proteins. Explain the role of the extracellular matrix in animals and plasmodesmata in plants. Compare and contrast endocytosis with exocytosis. What is osmosis? Define what a hypotonic solution is. Define what a Hypertonic solution is. Define what an isotonic solution is. Explain how knowing the tonicity of a cell can help us predict whether water will move into it, out of it, or flow in and out at equal rates? What is homeostasis? Explain how the overall structure of the cell membrane enables it to regulate how... a) nonpolar molecules move into and out of cells water moves into and out of cells b) ions move into and out of cells c) how A major theme in Biology is Homeostasis. Explain how the membrane is involved in a cell's homeostasis by discussing the role of each of the following... a. Diffusion b. Facilitated Transport c. Active Transport
