In short water is a reason to life on EARTH. What ever, water is all around. Health experts speak about increasing body mass, actually speaking they increase the water retention capability of our body. 85% of the body mass of any living creature on this EARTH is WATER.
You don't trust me? Would you like to try it out yeah?
If yes then it is a lethal test.
Wanna try it or ever tried on others?

Generally three process occurs during photosynthesis it is 1. Absorption of light energy by chlorophyll second is conversion of light energy into chemical energy and splitting of water molecules into hydrogen and oxygen 3rd is conversion of light energy into chemical energy so it is possible.

Generally, in the light phase step-2 photolysis that means hill's reaction takes place in that is by taking energy from sun-light water molecule splits into hydrogen and hydroxyl ions in that hydroxyl ions further react and lastly forms oxygen and water. So it is possible guys.

In 6 molecules of water only 6 oxygen atoms are present and 12 oxygen atoms are required to make 6 oxygen molecule. So alone from water we could not get the required no of atoms. So oxygen from CO2 will also be required to complete the reaction.

Ref : Rubin , Hassid and kamen who experimentally proved that oxygen liberated during photosynthesis comes from water.
Actually, the reaction is;
6 CO2 + 12 H2O - C6 H12 O6 + 6 O2 + 6 H2O.
Actually, the reaction is;
6 CO2 + 12 H2O - C6 H12 O6 + 6 O2 + 6 H2O.

6 CO2 + 6 H2O - C6 H12 O6 + 6 O2
i.e., carbon-di-oxide when reacted with water molecules splits into glucose and oxygen

In photosythesis the water molecules splits then the electrons are excited used protons finally the the electrons are free and it will fues protons and forms water molecules.

During photosynthesis, plants absorb water nd carbon, after Absorption, the water molecules disassembled and converted into sugar and oxygen.

Ruben's experiments using 'heavy water', H218O, to yield 18O2 gas had shown that the oxygen gas produced in photosynthesis comes from water.

Photosynthesis occurs in the presence of water. Therefore water dissociates to form oxygen atoms thereby releasing oxygen.
