What's the difference between nitrogen and organogen?
Nitrogen
Definition:
(n.) A colorless nonmetallic element, tasteless and odorless, comprising four fifths of the atmosphere by volume. It is chemically very inert in the free state, and as such is incapable of supporting life (hence the name azote still used by French chemists); but it forms many important compounds, as ammonia, nitric acid, the cyanides, etc, and is a constituent of all organized living tissues, animal or vegetable. Symbol N. Atomic weight 14. It was formerly regarded as a permanent noncondensible gas, but was liquefied in 1877 by Cailletet of Paris, and Pictet of Geneva.

Organogen
Definition:
(n.) A name given to any one of the four elements, carbon, hydrogen, oxygen, and nitrogen, which are especially characteristic ingredients of organic compounds; also, by extension, to other elements sometimes found in the same connection; as sulphur, phosphorus, etc.
Example Sentences:
(1) Unlike previous studies with 13-cis-retinoic acid during the pre- and early organogenic stages of development (Hummler et al., Teratology 42:263-272, 1990), no thymic hypo- or aplasia or heart anomalies were observed, which may be attributable to the slightly longer 13-cis retinoic acid treatment period, i.e., GD 10-27.
