GASEOUS EXCHANGE IN PLANT'S LEAVES 

BASICS OF IT IN PLANTS

  • Plant cells require oxygen and produce carbon dioxide during respiration
  • During photosynthesis plant cells take in carbon dioxide and produce oxygen
  • Some of the oxygen and carbon dioxide from photosynthesis and respiration are used for some of the other process (e.g. oxygen produced in photosynthesis is used for respiration and vice versa)
  • Excess of the oxygen and carbon dioxide diffuse out of the plant 
  • O2 and CO2 are in gases so diffuse more rapidly 

STRUCTURE - of plant leaf 

  • Short and fast diffusion pathway
  • Waxy cuticle layer on upper
