Biology of Plants may be a simple place to start, but I like this animation from Interactive Concepts in Biochemistry. These animations from the Online learning Center are good too.
For the chemists, the RSC has a page on photosynthesis, from their excellent Chemistry for Biologists resource. For the brave, there is also a photosynthesis quiz! There are lots of movies of Photosynthesis on Youtube, but please dont ask me to sing!

La la la la, fingers in ears!
