Detailed explanation-1: -Splitting of H2O molecules into hydrogen ions and oxygen in the presence of light and stroma is photolysis.

Detailed explanation-2: -You will find out that water is made up of hydrogen and oxygen atoms, and that we can split the atoms in a water molecule apart using electricity. This process of using electricity to drive a chemical reaction, like splitting water molecules apart, is known as “electrolysis."

Detailed explanation-3: -During Light reactions of Photosynthesis, the chlorophyll will be activated by light. This light activated chlorophyll will split the water molecule. This process is called Photolysis. Water molecule is split to release H+ ions and also oxygen.

Detailed explanation-4: -In water electrolysis, the source of energy used for the reaction to occur is electricity. An easy way to generate electricity is with a battery.
