2.67a)- Excretion in Plants

Recall the origin of carbon dioxide and oxygen as waste products of metabolism and their loss from the stomata of a leaf


Photosynthesis: 
CO2 + H2O ==> C6H12O6 + O2

  • Oxygen is a waste molecule and is an example of excretion
Respiration:
 C6H12O6 + O2 ==> ATP+ CO2 + H2O
  • Carbon dioxide is excreted by the plant as it is a metabolic waste
