Autotrophs
Chloroplasts
• Contain chlorophyll
– Green
• Site of photosynthesis
• Concentrated in leaves
Chloroplast Structure
Overview of Photosynthesis
• Light Reaction (stage 1)
– Occurs in thylakoid membranes of granna
– Converts light energy to chemical energy
– O2 produced as waste product
• Calvin Cycle (stage 2)
– Melvin Calvin
– Occurs in stroma of chloroplasts
– Synthesizes sugar molecules with CO2 &
energy produced in light reactions
