9) What do organic molecules have in common?
C & H
13
10) What do inorganic molecules have in common?
C or H or neither
14
11) Organic vs. Inorganic (Review)
Have C or H or neither, but never both at the same time. Can be found in living things Organic Have C & H together Made by living things
15
12) Organic compounds are made by Living Things
CO2 + H2O O2 + C6H12O6 organic inorganic
