What's the difference between organogen and oxygen?
Organogen
Definition:

(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.
Oxygen
Definition:
(n.) A colorless, tasteless, odorless, gaseous element occurring in the free state in the atmosphere, of which it forms about 23 per cent by weight and about 21 per cent by volume, being slightly heavier than nitrogen. Symbol O. Atomic weight 15.96.
(n.) Chlorine used in bleaching.
Example Sentences:
