Photosynthesis
Organisms that make food through photosynthesis: Photoautotrophs
Photosynthesis happens in the Chloroplast
• Parts of a Chloroplast
– Thylakoid
– Grana• Stack of Thylakoids
– Stroma• Liquid inside Chloroplast
Photosynthesis Equation
Melvin Calvin
The electromagnetic spectrum
Why are leaves green?
Determining an absorption spectrum
Chlorophyll is a Pigment
Pigments•Give a substance color•Plant pigments
•Chlorophyll a – blue-green•Chlorophyll b – yellow-green•Carotenoids – yellow/ orange
Electrons in chlorophyll are excited by light
How a photosystem harvests light
Cyclic Electron Flow: ATP Only
ATP is made in the Thylakoid Membrane
Comparison of chemiosmosis in mitochondria and chloroplasts
The Calvin Cycle converts CO2 into Sugar
C4 leaf anatomy and the C4 pathway
•Hot, dry environments•Conserve water•Prevent photorespiration
C4 and CAM photosynthesis compared
