Given the equation:
6CO\(_2\) + 6H\(_2\)O → C\(_6\)H\(_{12}\)O\(_6\) + 6O\(_2\) (Under sunlight & Chlorophyll)
The oxygen given off during the above process is derived from
sunlight
chlorophyll
carbon dioxide
atmosphere
water

6CO2 + 6H2O--->C6H12O6 + 6O2, the oxygen which is the by product is gotten from water via a process called photolysis or photodissociation.
for photosyntsis to place water must be involve,sunlight also, so when the wate moleculs come in contact with light they breaking to lebrate oxyge to atmosphere,which is later used by animals n so othe plant.
During photsynthesis,water is photolysed,split into Hydroden ion and hydroxonium ion. the hydroxonium ion then react togetyer to release oxygen.
H2O---- OH +H
20H+20H--- 2H20+O2
There oxygen gotten from water is obtained by the spliting of water through sunlight in a process known as PHOTOLYSIS
By using the energy of sunlight, plants can convert
carbon dioxide and water into carbohydrates and
oxygen in a process called photosynthesis. As
photosynthesis requires sunlight, this process only
happens during the day. We often like to think of this
as plants `breathing in carbon dioxide and `breathing
out oxygen .
In an experiment that was carried out ,the oxygen present in the water was radioactive and the oxygen gas that was given off in that experiment was radioactive thus,the oxygen is gotten from water
@tommy,yea we ol knw d primary source of oxygen is d atmosfere..bt here we are askd 2 take ref.2 d equation.. During d light phase of photosyntesis(photolysis)..the H0- ion produced react wit anoda H0- ion den,wata(H20) n oxygen gas r libr8d
in the presence of light, the chlorophyl is energised and supplies energy which is used to break water molecules obtained from the soil into hydroxyl and hydrogen ions H2O--> OH + H (this process is called photolysis of water).The hydroxyl ions are later converted to water and oxygen gas 4OH --> 2H2O + O2. i.e the oxygen given off during photosynthesis is gotten from soil water.
