I know that angiosperms don't synthesize chlorophyll in the dark, their 
protochlorophyllide reductase is light dependent (honestly I don't remember why, 
whether its transcription of the gene etc). I cut open a lemon last night; why 
was the germinated seed I found green? Lemon skin is pretty thick, can enough 
light penetrate it (in the fridge for the last 10 days or so) to induce 
chlorophyll synthesis? Thanks a lot,   Andrea Auchincloss
