1  AKA “Plasma Membrane” or “Fluid Mosaic”

2  Selectively permeable  Barrier  Protection

3  Phospholipids (Bilayer)  Transport & Receptor Proteins  Some Carbohydrates and Cholesterol (fluidity)

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

5  Exocytosis- active removal of materials from cell (vesicle)  Endocytosis- active way to bring materials into cell (vesicle)

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
