Mario sets up an experiment to determine the source of the oxygen gas produced by photosynthesis. To determine this, he uses an

isotope of oxygen called O-18. He labels the O-18 oxygen so he can follow its path through photosynthesis. Plant A is given carbon dioxide that contains the O-18 isotope. Plant B is given water that contains the O-18 isotope. When he examines the oxygen from both plants, only plant B produced O-18 oxygen. What conclusion should he draw about the source of oxygen produced through photosynthesis?

Mario sets up an experiment to determine the source of the oxygen gas produced by photosynthesis. To determine this, he uses an isotope of oxygen called O-18. He labels the O-18 oxygen so he can follow its path through photosynthesis. Plant A is given carbon dioxide that contains the O-18 isotope. Plant B is given water that contains the O-18 isotope. When he examines the oxygen from both plants, only plant B produced O-18 oxygen. This indicates that the source of oxygen is water. The photosynthesis involves the transfer of electrons between the photosystem I and II. The water gets split into oxygen, hydrogen ions and electrons in the photosystem I. The electrons move to the photosystem II where the carbon fixation into sugars takes place. The plant A will have O-18 isotope in its synthesised sugar molecule, which gets stored inside it.

This type of bond results in the exchange of electrons?
MissTica
An ionic bond results in an exchange or transfer of electrons between the 2 different types of atoms, most likely the metal atom and nonmetal one.

For example the compound NaF is held together by electrostatic forces of positive and negative charges due to the transfer of electrons from the sodium to fluoride atom.
