[n] a living thing that has (or can develop) the ability to act or function independently
[n] a system considered analogous in structure or function to a living body; "the social organism"



Webster (1913) Definition: Or"gan*ism, n. [Cf. F. organisme.]
1. Organic structure; organization. ``The advantageous
organism of the eye.'' --Grew.

2. (Biol.) An organized being; a living body, either
vegetable or animal, compozed of different organs or parts
with functions which are separate, but mutually dependent,
and essential to the life of the individual.

structure as to be without organs, but are still called
organisms, since they have different parts analogous in
functions to the organs of higher plants and animals.
