The Mechanics of Photosynthesis
The Big Picture
Photosynthesis is the process where autotrophs convert solar energy into chemical energy stored in glucose.
6CO2 + 6H2O + light → C6H12O6 + 6O2
Chemical Overview
Reactants
CO2, H2O, Sunlight
Products
Glucose, O2
Chloroplast Structure
1. Thylakoid
Flattened membrane sac. Site of the Light Reactions.
2. Stroma
The fluid space outside grana. Site of the Calvin Cycle.
3. Granum
A stack of thylakoids (multiple are grana).

Hook: Plants as solar panels. Discuss how batteries store energy.
25m
Input: Present slides. Focus on the transformation of energy from light to sugar.
15m
Check: Quiz for understanding. Focus on reactants vs products.
Key Facts
Misconception
Plants "breathe" CO2 to get O2.
Fact: O2 comes from splitting water (H2O) molecules.
Misconception
ATP is the final food.
Fact: ATP is short-term energy. Glucose is the long-term storage.
