Limitations
• Optimal PS requires• Rubisco acitivity• Regeneration of RuBP• Metabolism of Triose phosphates
Sun and shade leavesSun leaf Shade leaf
• Sun leaves thicker, palisade cells elongated, more rubisco, more xanthophyll cycle components
• Shade leaves thinner, more total chlorophyll per reaction center, more chl b,
