1. THE Ingredients for Life

2. Where did Biomolecules come from?
To begin learning about CELLS we must understand how biomolecules were formed.
Scientists knew that early earth had raw materials such as:
Water,
Hydrogen gas,
Nitrogen,
Ammonia,
Methane,
Carbon dioxide and Carbon monoxide.

3. Organic Compounds Lets Recall(remember) that:
Organic Compounds - have carbon bonded to other atoms and determine structure/function of living things
Inorganic Compounds - do not contain carbon and hydrogen together (example:salt)

4. All Living Organisms are Composed(made) of……
Can you name the Elements found in all living organisms
Carbon
Hydrogen
Oxygen
CHONP(S)

5. Cells and Elements
All living organisms are made up of elements (CHO) --> CHO make molecules (like biomolecules) ---> Biomolecules organized in to cells---> Cells can be organized in to organisms.

6. Where the heck did all of these elements & molecules come from?
Lets watch a short video that explains more.
Remember that we are going to learn about cells and cells are composed of biomolecules.
Sooooo we are try to figure out where the elements that make up biomolecules came from………….
How did molecules form (video)?

7. 1920 - The Primordial Soup Theory is born.
In the early 1920’s Russian Chemist A.I. Oparin and English Geneticist J.B.S. Haldane conceived the idea of primordial soup.
Primitive earth contained elements (CHONPS) that later formed organic molecules (biomolecules)
Energy from the sun's UV rays, lightning and rain and extreme temperatures helped form molecules from CHONPS

8. Miller and Urey
In 1953 Stanley Miller and Harold Urey tested the Primordial Soup theory.
Water Vapor (H20)
Water (liquid)
Carbon Dioxide (CO2)
Oxygen (O2)
Ammonia (NH3)
Methane (NH4)
Energy (lightning)
Heat source (high temperatures)
