2.67a Excretion in plants

1. Photosynthesis absorb light energy and turn CO2 + H20 -> C6H12o6 + O2 (  where O2 is the Excretion)


2. Aerobic respiration


                       Enzyme            
C6H12O6 + 02 ------------> ATP + Co2 ( excretion) + H20


Plants excrete Oxygen and Carbon Dioxide depending upon the process it is doing.
