Photon Mass?

Hi there,

IÕm in a graduate tree physiology course and I ran into a question that no
had an answer to.  We had a brief refresher on photosynthesis (at a very
level), and while we were discussing how the energy of photons was 
transferred, I remembered something about a controversy as to whether or 
not a photon contained mass.  So my question is: Does a photon have mass or
it just an energy wave?

Thanks for any answers I get.
