What's the difference between organogen and phosphorus?
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.

(20) Acid phosphatase activity in particularly organogenic strain of tobacco has been localized in two kinds of tissue: the internal bud primordia and the adjacent tissues.
Phosphorus
Definition:
(n.) The morning star; Phosphor.
(n.) A poisonous nonmetallic element of the nitrogen group, obtained as a white, or yellowish, translucent waxy substance, having a characteristic disagreeable smell. It is very active chemically, must be preserved under water, and unites with oxygen even at ordinary temperatures, giving a faint glow, -- whence its name. It always occurs compined, usually in phosphates, as in the mineral apatite, in bones, etc. It is used in the composition on the tips of friction matches, and for many other purposes. The molecule contains four atoms. Symbol P. Atomic weight 31.0.
(n.) Hence, any substance which shines in the dark like phosphorus, as certain phosphorescent bodies.
Example Sentences:
