Presentation Transcript

  1. AKA “Plasma Membrane” or “Fluid Mosaic” Cell Membrane

  2. Selectively permeable Barrier Protection Function

  3. Phospholipids (Bilayer) Transport & Receptor Proteins Some Carbohydrates and Cholesterol (fluidity) Made of…….

  4. 2 Types of Transport Active- takes energy (ATP) & Protein -(Against Concentration Gradient) Passive- No ATP needed (Down Concentration Gradient) -Diffusion (facilitated as well w/ protein) - Osmosis- diffusion of water http://www.biology4kids.com/files/cell2_activetran.html Types of Transport

  5. Exocytosis- active removal of materials from cell (vesicle) Endocytosis- active way to bring materials into cell (vesicle) Other Types of Active Transport

  6. Solvent- the liquid (H2O) Solute- the substance being dissolved (Salt or Sugar) Hypotonic- solution is lower concentration of solute Hypertonic-solution is higher concentration of solute Isotonic- concentration is equal Concentration
