Can plants produce oxygen without carbon dioxide? What is the relationship between carbon dioxide and oxygen in plants?

Okay i found that it is

No, it can't because the photosynthesis involves different types of processes with carbon dioxide, producing oxygen as the result.

The relationship in the reaction is:

CO2 + 2H 2O + photons → [CH2O] + O2 + H 2 O, so one molecule of carbon dioxide turns into one molecule of oxygen.
