1. Big Idea #2: Energy is needed to do stuff.
Photosynthesis
Big Idea #2: Energy is needed to do stuff.

2. Essential Knowledge
2A2: Organisms capture and store free energy for use in biological processes.

3. Producers: Phototrophs
Use free energy solar radiation to produce sugar (PS)
Plants, Algae (Phytoplankton), Bacteria

4. PS Occurs in Chloroplasts
Found in all green parts
Most abundant in mesophyll cells
Chlorophyll: green pigment that captures free energy sunlight.

5. Chloroplast Structure
Thylakoids are membrane-bound discs
Outside fluid is called the stroma
Contained in a double membrane

6. Chloroplast x5,755

7. Producers: Chemotrophs
Capture free energy from small inorganic molecules (H2S) to produce sugars (chemosynthesis)
Can occur w/out O2.
Bacteria

9. Made foundation for eukaryotic PS.
Evolution of PS
Started in prokaryotic cells (bacteria) and created an oxygenated atmosphere.
rRNA analysis
Made foundation for eukaryotic PS.
