Yes, except parent is correct. Physcial and chemical mean very different and specific things in this context.
Calling photosynthesis a physical reaction is flatly incorrect no matter how you want to look at it. It is a physics reaction, sure, but "physical reaction" specifically means a Newtonian mechanical, reversible process at the macro scale.
A "chemical reaction" specifically means a (trivially) irreversible quantum/atomic reaction involving chemical bonds at the atomic/molecular scale.
