How photosynthesis works at a cell machinery level is high school level biology.

That's not an understanding of how it works

I disagree. It very much is an understanding of how photosynthesis works, it isn't a complete understanding sure, but an understanding nonetheless.

Unless you're going to argue that we don't know how an MRI works because we don't fully understand the physics behind superconductivity.
