In biology, an organism is any contiguous living system (such as animal, fungus, micro-organism, or plant). In at least some form, all organisms are capable of response to stimuli, reproduction, growth and development, and maintenance of homoeostasis as a stable whole.
An organism may either be unicellular (single-celled) or, as in the case of humans, comprise many trillions of cells grouped into specialized tissues and organs. The term multicellular (many-celled) describes any organism made up of more than one cell.
The term "organism" (Greek ὀργανισμός – organismos, from Ancient Greek ὄργανον – organon "organ, instrument, tool") first appeared in the English language in 1701 and took on its current definition by 1834 (Oxford English Dictionary). It is directly related to the term "organization". There is a long tradition of defining organisms as self-organizing beings.[1]
