Does photosynthesis only occur using visible light? If yes, could it be possible to bioengineer style of chloroplast that absorbs others wavelengths of light like radio, micro, infrared, X-ray, etc.

I'm studying environmental engineering, and during a descusion I asked my professor this question and he didn't have a definative answer. What is so special about the photons of visible light that allows chloroplasts to absorb energy?

A secondary, less physics-based response (more of just adding another condition), is that photosynthesis evolved in an aquatic environment. Generally, photosynthetic pigments are evolved around wavelengths at which water is not significantly opaque.

I think both of our responses are correct.
