Study Notes
Photosynthesis
- Plants, bacteria and protists perform photosynthesis, a process that converts light energy into food
- Photosynthesis uses carbon dioxide, water and sunlight to produce glucose and oxygen
- The chemical equation for photosynthesis is 6CO2 + 6H2O → C6H12O6 + 6O2
- Photosynthesis in plants occurs in chloroplasts which are organelles in the leaf cells
- Chloroplasts are green because they contain chlorophyll, a pigment that absorbs light energy
- Chlorophyll absorbs blue and red wavelengths of light and reflects green wavelengths
- When chlorophyll absorbs light energy, electrons become excited and jump to a high energy level
- The excited electrons are transferred from chlorophyll to a primary electron acceptor
- Photosynthesis also uses accessory pigments that absorb other wavelengths of light and pass on the energy to chlorophyll
