What is the evidence for two photosystems?

The combination of light at 680 nm and 700 nm is much more effective in stimulating photosynthesis than is either wavelength alone.

Chlorophyll absorbs light of two different wavelengths: blue and red.

Two different high-energy molecules are produced during the light-dependent reactions of photosynthesis: ATP and NADPH.

Microscopy reveals two colors of chloroplast within the same leaf cell.
