Above the clouds the air is thin, and thus doesn't scatter much.  Overall, the atmosphere isn't a fiber-optic cable.Photosynthesis is not the only way to go.  Check out the deep sea near volcanic vents - no sunlight, but lots of life.  I only see one that references it, and it is more interested in whether the planet holds an atmosphere at all: <a href="http://en.wikipedia.org/wiki/Aurelia_and_Blue_Moon" target="_blank">Aurelia and Blue Moon - Wikipedia, the free encyclopedia</a>"Nonetheless, the scientists employed by the programme decided to test the traditional assumptions for such a planet and start a model out for it from a proplyd through to its eventual death. Their estimations suggested such a planet could indeed hold on to its atmosphere, although with freakishly unusual results by Earth standards. Half of Aurelia would be in perpetual darkness and would be in a permanent ice age. The other half would contain a giant, unending hurricane with permanent torrential rain at the point directly opposite the local star. In between these two zones would be a place suitable for life."Other links are about magnetic fields and fictional worlds.  Which ones am I missing?</blockquote>
