organic
In chemistry, organic refers to almost every species containing carbon. (Certain small ions and compounds containing carbon (such as carbon dioxide) are usually not considered to be organic, but rather are classed as inorganic.)

osmosis
The passage of solvent through a semipermeable membrane from a region of higher concentration of solute to a region of lower concentration of solute.
Osmotic Pressure, Hydrostatic Pressure
osmotic pressure
The pressure required to prevent solvent from passing through a semipermeable membrane from a region of higher concentration of solute to a region of lower concentration of solute.
Osmotic Pressure, Hydrostatic Pressure
oxidation
That part of a chemical reaction in which a reactant loses electrons; simultaneous reduction of a different reactant must occur as well as increase in the oxidation number of an element.
