Leaves of plants are adapted to carry out photosynthesis by having;

  • Broad and flat to create surface area of carbon(iv)oxide and absorption of sunlight.
  • Thin transparent upper epidermis to allow easier penetration to light to photosynthetic cells.
  • Thin for faster diffusion of gases.
  • Large/intercellular air space in the spongy mesophyll layer for storage of carbon (iv) oxide for easier gaseous exchange.
  • Waxy water proof cuticle to reduce water loss.
  • Palisade layer with numerous chloroplast to trap maximum amount of light for photosynthesis.
  • Leaf mosaic/non-overlapping leaves for maximum exposure to light.
  • Palisade cells placed next upper surface to trap maximum light for photosynthesis.
  • Guard cells are modified to pen and close stomata to control amount of water loss from the leaf and allow gaseous exchange.
