How would immersing an aquatic plant (placed under a white light/regular light
source)in different colored solutions affect the type light it receives? For
example, how would immersing an aquatic plant in a green solution affect the
light the plant actually receives? Would the green color of the solution cause
the green wavelengths of light to be reflected and therefore not reach the
submerged plant? Or would a phenomenon to the contrary occur (i.e. the green
wavelengths of light are absorbed, and other color wavelengths are reflected
away from the plant). Would immersing an aquatic plant in a green colored
solution therefore affect its rate of photosynthesis by determining what color
wavelengths of light it receives? I know that generally speaking, in normal
conditions, plant chlorophyll absorbs light of the blue and red part of the
spectrum and reflects green.
Thank you very much; any advice is much appreciated.
