Photosynthesis & Cell Respiration Add Far Side Cartoon

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 –O 2 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
