Autotrophs are the producers of the biosphere
Photosynthesis occurs in chloroplasts in plant cells
The Chloroplast
Plants produce O2 gas by splitting water
Photosynthesis is a redox process, as is cellular respiration
Overview: The two stages of photosynthesis are linked by ATP and NADPH
Visible radiation drives the light reactions
Interaction of light with a chloroplast
Photosystems capture solar power
Two photosystems connected by an electron transport chain generate ATP and NADPH
Chemiosmosis powers ATP synthesis in the light reactions
ATP and NADPH power sugar synthesis in the Calvin cycle
Review: Photosynthesis uses light energy, CO2, and H2O to make food molecules
Adaptations that save water in hot, dry climates evolved in C4 and CAM plants
