• 6CO+ 6H2O + sunlight ---> C6H12O+ 6CO2

    Carbon Dioxide + Water + Sunlight gives Glucose + Oxygen

  • How is a leaf adapted for light absorption:
    • Large SA
    • epidermis is transparent, allows sunlight to pass to palisade mesophyll 
    • palisade cells close to upper leaf surface
    • palisade mesophyll contains tightly packed cells
    • palisade mesophyll densely packed w/ c'plasts
    • c'plasts in palisade cells mostly packed at upper ples
    • leaf contains p'synthetic pigments capable of light absorption
  • Spongy mesophyll layer is less tightly packed + has numerous air spaces
    • form a continuous pathway from stomata on lower episdermis to the palisade cells
    • allows uninterrupted diffusion of gases + facilitates gas exchange
