genetic engineering...gene splicing
Glow sticks
yes, mushrooms do glow in the dark but only a few kinds and it is poisonous.
chemical
It doesn't. Radium is radioactive. Radium plus a phosphor glows in the dark.
Because it is indeed radioactive. It glows in the dark and is commonly used in expensive watches and firearms sights. (gamma radiation?)
fungus
An impossibility. Tobacco is a plant that is dependent on photosynthesis for it to grow. There are tobacco plants which have been gene-spliced to glow in the dark, though.
Agrobacterium-mediated transformation using a plasmid containing a gene for GFP
I don't think so. You can look it up online.
FireFlies
It absorbs light so it can glow in the dark.
A liquid because it glows in the dark

Bruce Coville.
None, to my knowledge anyway.
