10. Two Types of molecules
Organic
Inorganic

11. What do molecules have in common?
ORGANIC: Carbon and Hydrogen
(C) and (H)
INORGANIC: Carbon and Oxygen C O
They are missing C or H or both!

12. Molecules Organic Inorganic Have C & H together
Made by living things
Inorganic
Missing the carbon or hydrogen or both.
Can be found in living things

13. Organic compounds: are made by Living Things
