You can test it for yourself - you will be able to detect a green trafic light much further away than a red or yellow one especially during the day. Another interesting thing is to look at satellite pictures from Google and note how dark the vegetated areas appear compared to the cities. That seems to confirm that plants are absorbing some of the green spectrum but just not quite as much as the others in keeping with the postulate that plants ~ought to~ have evolved to absorb as much solar enrgy as they possibly can. I would surmise that the reflective index of materials that comprise the mechanical supporting structures within the leaf surface would be of a wavelength providing the least opaque-ness to the wavelengths that that the plant can utilize the best. IE - "Green light does the least for me, my supporting cell structures have to have some pigment, so having them green is the most efficient color to use."Mike Mnoreply@blogger.comtag:blogger.com,1999:blog-18646885.post-56097711786627883182009-06-27T11:54:40.464-07:002009-06-27T11:54:40.464-07:00Steven,
