What does organismal mean?
Organismal is a formal biological adjective meaning relating to organisms or to the properties and processes of living beings as wholes. It is especially used in scientific research to describe organismal growth, development, reproduction, response, or variation. The word is useful when an effect or characteristic belongs to an entire organism, rather than only to one of its cells, tissues, organs, or molecular components. For example, scientists might compare the organismal response to heat stress with the response of isolated cells, since the whole organism involves coordinated systems that can modify or reverse effects seen at smaller scales. In general use, organismal has a technical tone and is less common than broader terms such as biological or living, but it conveys the more specific idea of a characteristic considered at the level of the organism.

Where does organismal come from?
Organismal was formed in the 19th century from organism plus the adjective-forming suffix -al, meaning “relating to” or “pertaining to.” Its vocabulary roots ultimately extend through Latin organismum, a term associated with an organized structure, and Greek organon, meaning “an instrument or means.” Related English words include organism, organize, organization, and organic, all reflecting the same broad idea of organized living structure.

How organismal is actually used
This is a formal scientific term, most common in biology, ecology, medicine, and environmental science. It is usually used when a property or process concerns an organism as a whole rather than a single cell, molecule, or organ.
