Not sure how to post a question =96 but here is one that I have been =
wondering
about.

=20

Simply =96 Why are plants green?

=20

I understand about absorption and reflection by photosynthetic pigments =
but
my real questions is why have plants not evolved abundant molecules that
absorb green light for use in photosynthesis. I know that there are some
plants that have higher levels of anthocyanins and other photosynthetic
flavonoids but why don=92t most plants?

=20

Also =96 If plants did make more complete use of the visible portion of =
light
=96 what color would they be? I am guessing more like black or darker =
shades?
