What is the formula for photosynthesis

The formula of photosynthesis can be written as shown below.
6CO2 + 6H2O > C6H12O6 + 6O2
                          Sunlight
In the above equation,
CO2 = Carbon Dioxide
H2O = Water
C6H12O6 = Glucose
O2 = Oxygen.
Carbon dioxide and water react together in presence of sunlight to produce glucose as food for the plant and oxygen that gets released in the air.Plants require the process of photosynthesis for their own survival They absorb the carbon dioxide from the air and release the oxygen that is required for the survival of most living things.

Photosynthesis can be represented using a chemical equation.The overall balanced equation is...6CO2 + 6H2O > C6H12O6 + 6O2
Sunlight energy Where: CO2 = carbon dioxide 
H2O = water
Light energy is required
C6H12O6 = glucose

o2=oxigen2=oxigenn

That is true tge cactus as a structural adaptation to its envirinment has it leaves reduced to spines. but this doesnt mean it cant produce food it produces food because of the presence of chlorophyll in its stem
