2.39 understand gas exchange (of carbon dioxide and oxygen) in relation to respiration and photosynthesis

In photosynthesis: 6CO2 + 6H2O > C6H12O6 + 6O2 + 6H2O
So the plant takes up carbon dioxide and gives out oxygen

In respiration: C6H12O6 + 6O2 > 6CO2 + 6H2O
So the plant gives out carbon dioxide

    Your equation for photosynthesis is wrong. It should be 6CO2 + 6H2O > C6H12O6 +6O2

      She is busy and since it's already been corrected by the top comment there's no need to. Stop, stop insulting people for no justifiable reason.

    Also I think you made a small mistake, in respiration H2O is not a raw material, rather O2 is :) to produce H20

    Otherwise another helpful point

    It should also be 6O2 for respiration
