Answer 1

in photosynthesise the wayer undergoes to the root while caron dioxide go to the leaf absorbed by plants to make there food.they carbon use release oxygen

Answer 2

In photosynthesis water undergoes oxidation and carbon dioxide undergoes reduction.
6CO2 + 6H2O ------> C6H12O6 + 6O2


From H2O, hydrogen is removed to convert to O2. Hence it is oxidized.

To CO2, Hydrogen is added to convert to C6H12O6, and hence it is reduced.
