Is photosynthesis a displacement reaction? If yes is it single displacement or double?

Dear Student,

Photosynthesis is a single displacement reaction.

This is the reaction for photosynthesis:

6CO2 + 6H2O → 6O2 + C6H12O6

During the light reactions of Photosynthesis, the water molecules, hydrogen ions are separated from the molecular oxygen atoms, which combine to form oxygen gas molecules which are released into the atmosphere as a waste product.
