leaves

• Functions of the Leaf

  • Photosynthesis
  • Gas Exchange
• Photosynthesis


  Conversion of light energy into chemical energy (glucose) using chlorophyll and other pigments, from carbon dioxide and water
• Gas Exchange

  Stomata facilitate the intake of CO2 for photosynthesis and the release of O2 during respiration
• Transpiration

  Loss of water vapor through stomata, crucial for nutrient uptake and cooling
• Leaf Adaptations - Xerophytes (Desert Plants)

  • Thick, reduced leaves minimize water loss
  • Stomata open only at night to conserve water
  • Thick waxy layer (cuticle) prevents water loss
