Lab 4 Photosynthesis

• Description
• determine rate of photosynthesis under different
  conditions
• light vs. dark
• boiled vs. unboiled chloroplasts
• chloroplasts vs. no chloroplasts
• use DPIP in place of NADP
• DPIPox blue
• DPIPred clear
• measure light transmittance
• paper chromatography to separate plant pigments

Lab 4 Photosynthesis

• Concepts
• photosynthesis
• Photosystem 1
• NADPH
• chlorophylls other plant pigments
• chlorophyll a
• chlorophyll b
• xanthophylls
• carotenoids
• experimental design
• control vs. experimental

• Conclusions
• Pigments
• pigments move at different rates based on
  solubility in solvent
• Photosynthesis
• light unboiled chloroplasts produced highest
  rate of photosynthesis

Which is the control?
2 (DPIP chloroplasts light)
