2. 70% of cytoplasm is water 96% of Cell is CHNOKS Carbon, hydrogen, nitrogen, oxygen, potassium, sulfur 5,000 different compounds Only has to absorb a few nutrients to synthesize all of these. Can make most everything they need

3. Contain carbon Have covalent bonds Have low melting points Have low boiling points Burn in air (oxygen) Are soluble in nonpolar solvents Form large molecules

4. Contain only carbon and hydrogen May contain single, double or triple bonds between carbon atoms C C C=C or C C Primary compounds present in petroleum

5. Contain C and H only Contain single bonds C-C Have 4 bonds to every carbon (C) atom Are nonpolar

6. Show the bonds between each of the atoms CH4, methane
