a process whereby molecules of water may have their hydrogen split from the oxygen, because of light energy present on chlorophyll

Photolysis refers to any chemical reaction in which a compound is broken down by light.
 Photolysis in photosynthesis
Photolysis is a part of the light-dependent reactions of photosynthesis. The general reaction of photosynthetic photolysis can be given as:
H2A + 2 photons (light) 2e- + 2H+ + A ...

Meanwhile the photosystem's stolen electron is replenished by photolysis, or the splitting of H2O to form H+and O2 (note: the H+ is kept in side the thylakoid membrane). The O2 resulting is the source of all oxygen in our atmosphere ...
3.8.6 State that ATP and hydrogen (derived from the photolysis of water) are used to fix carbon dioxide to make organic molecules.
ATP and hydrogen derived from photolysis of water are used to fix carbon dioxide to make organic molecules.
a) (i) oxygen produced during photolysis/using light energy; from breakdown of water
(ii) DCPIP accepted hydrogen/protons/H+

Hill reaction The splitting of a molecule of water during the light reactions of photosynthesis; the photolysis of water.
hilum Scar on a seed indicating where it was attached to the ovary.
These electrons and hydrogen ions come from the photolysis of H2O into O2 and electrons e- and H+. So, as we discussed earlier, a plant uses water and carbon dioxide and sunlight to make sugars and oxygen.
