In Biology, an organism is any contiguous living system (such as animal, plant, fungus, or micro-organism). 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 be composed of, as in humans, 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).
Scientific classification in biology considers organisms synonymous with "life on Earth". Based on cell type, organisms may be divided into the prokaryotic and eukaryotic groups. The prokaryotes represent two separate domains, the Bacteria and Archaea. Eukaryotic organisms, with a membrane-bounded cell nucleus, also contain organelles, namely mitochondria and (in plants) plastids, generally considered to be derived from endosymbiotic bacteria.[1] Fungi, animals and plants are examples of species that are eukaryotes.
More recently a clade, Neomura, has been proposed, which groups together the Archaea and Eukarya. Neomura is thought to have evolved from Bacteria, more specifically from Actinobacteria.[2]
I assume you meant single "celled" organism. It is an organism (life form) that consists of only a sigle cell as opposed to most all other lifeforms on earth which are comprised of many (billions) of cells.
We are multicellular. A multicellular organism contains more than one cell. A single-celled organism might be called 'unicellular'.
An organism (a living thing ... plant or animal) that consists of a single cell. Like an amoeba or a paramecium.
By definition, a single celled organism consists of only one cell. If it were to have two or more cells we would call it a multi-cellular organism.
Eukaryote
A single celled organism is called unicellular.

single celled organisms or microorganisms
Most bacteria are single cell organisms.
We are multicellular. A multicellular organism contains more than one cell. A single-celled organism might be called 'unicellular'.
Any (single) living organism that consists of more than a single cell.
A unicellular organism that has only one cell. One of the largest of these is called Valonia centricosa. Bacteria is also in this classification. They carry out life processes to survive.
paramecium
An prokaryotic cell organism like bacteria answered by m.buallay
