2)Two photosystems operating simultaneously.

As discussed in

Red Drop -

Sharp reduction in rate of photosynthesis when monochromatic light of more than 680 nm wavelength (red region) was used alone.

- wherein

680 \: nm \uparrow - Red drop effect

 

 

Emerson Enhancement Effect -

Simultaneous application of light of shorter and longer wavelengths, increases the rate of photosynthesis.

- wherein

680 \downarrow \: + 680nm \uparrow \: - Emersion \: Effect

 

 Emerson's Enhancement effect and Red drop is due to the presence of two photosystems PS I and PS II.
