This is going off topic but what an interesting idea... Can plants work day and night if you give them light 24x7? I assume they don't need to rest or get tired?

Plants do indeed have day night cycles, so they do need rest.

Just Google plant day night cycle.

This depends, as far as I know, if the plant is doing C-3 or C-4 photosynthesis.
