Chlorophyll absorbs light most strongly in the blue and red but poorly in the green portions of the electromagnetic spectrum, hence the green color of chlorophyll-containing tissues like plant leaves. orga:ClathrateHydrate orga:GasHydrate orga:HC orga:HCFC orga:Halon orga:Hydrocarbon orga:Hydrochlorofluorocarbon orga:MethaneClathrate orga:MethaneHydrate orga:MethaneIce orga:NMVOC orga:NonMethaneVolatileOrganicCompound orga:OrganicCompound orga:OrganicSubstance orga:Organochloride An organochloride, organochlorine, or chlorocarbon, is an organic compound containing at least one covalently bonded chlorine atom.
