Vedclass · Answer

(B) During the process of photosynthesis,the oxygen released as a byproduct comes from the photolysis of water $(H_{2}O)$,not from carbon dioxide $(CO_{2})$.This was experimentally proven by Ruben and Kamen using the heavy isotope of oxygen,$^{18}O$.Therefore,if a plant releases oxygen containing $^{18}O$,it indicates that the water supplied to the plant contained the $^{18}O$ isotope.

If a photosynthesising plant releases oxygen containing more than the normal amount of $^{18}O$,it is concluded that the plant has been supplied with:
