List two bi-products of photosynthesis

The two byproducts of photosynthesis are glucose and water.

Explanation:

Photosynthesis is the process in which light energy is converted into chemical energy. Here, Carbon-di-oxide and oxygen are the reactants.  These two components combine to form the byproducts are Glucose(sugar) and water. The molecular formulae for glucose are C₆H₁₂O₆.The general equation for photosynthesis:

        6CO₂          +   6H₂0   →   C₆H₁₂O₆   +   6O₂

(Carbondioxide)    (Water)       (Sugar)        (Oxygen)
