In greenhouse grown leaves of broad bean stomatal movements closely correlate with incident solar radiation at the leaf surface and stomatal aperture  opening and closing as light levels reaching the leaf surface given in graph

 


A. Mid of the day stomatal aperture has a largest diameter, water loss and transpiration rate will be highest at the  same time

B. In mid of the day incident light is highest in terms of PPFD and can also say CO2 diffusion will be highest

C. The stomatal aperture has a largest diameter resulting closing of stomatal pore, water loss and transpiration rate will be lowest due to closing of stomata

D. In mid of the day incident light is highest in terms of PPFD resulting CO2 will not diffuse
