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 the leaves.

Let's start with photosynthesis, which uses light energy to turn CO2+H2O=>C6H12O6+O2 [Excretion]
In respiration in plants with aerobic respiration C6H12O6+O2=enzymes>ATP+CO2[Excretion]+H2O

So in conclusion plants excrete Oxygen and Carbon Dioxide depending upon the process it is doing.
