An organism is defined in a medical dictionary as any living thing that functions as an individual. [1] Such a definition raises more problems than it solves, not least because the concept of an individual is also difficult.
A microorganism, or microbe, [a] is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells. The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from sixth century BC India.
Organisms are a biotic, or living, part of the environment. Rocks and sunshine are parts of the non-living environment. Organisms usually have six basic needs to continue their metabolism. They need air, water, nutrient (food), energy, a place to live, and homeostatsis (being able to maintain itself).
Biology is the science of life. It spans multiple levels from biomolecules and cells to organisms and populations.
A micro-organism or microbe is an organism which is microscopic, which means that they are so small that people cannot see them with the naked eye. The study of microorganisms is called microbiology. Micro-organisms include bacteria, fungi, archaea, protists and viruses, and are among the earliest known life forms.
There are 3 recognized domains, or broadest classification of organism. These are Bacteria, Archaea, and Eukarya. In the simplest case, an organism can be a bacteria, a DNA molecule containing genetic information wrapped in a protective plasma membrane.
An organism refers to a living thing that has an organized structure, can react to stimuli, reproduce, grow, adapt, and maintain homeostasis. An organism would, therefore, be any animal, plant, fungus, protist, bacterium, or archaeon on Earth. These organisms may be classified in various ways.
organism (plural organisms) (obsolete, rare) The fact of being organic; organicity. [18th–19th c.] Something with many separate interdependent parts, seen as being like a living thing; an organic system. [from 18th c.]
An organism is an individual life form with characteristics that set it apart from rocks, minerals or viruses. An organism by definition must have the capacity to metabolize, grow bigger, react to stimuli, reproduce and maintain homeostasis.
An organism is any system of components which depend on each other for survival and cooperate in proliferating potentially unboundedly. A single-celled organism is by this definition an organism since it proliferates by coordination of its components.
A model organism is a non-human species that is extensively studied to understand particular biological phenomena, with the expectation that discoveries made in the model organism will provide insight into the workings of other organisms.
Un organism este un sistem deschis care face schimburi de materie, energie și informație cu mediul înconjurător, este „viu”, are „viață” (trăiește) o anumită perioadă limitată, care se sfârșește odată cu moartea organismului. Organism este și orice individ din cadrul unei specii.
An organism is a living entity composed of one or more cells, capable of growth, reproduction, and response to stimuli, functioning as an individual life form. Structure of an Organism. Every organism, whether unicellular or multicellular, is fundamentally composed of cells, the basic structural and functional units of life.

A unicellular organism, also known as a single-celled organism, is an organism that consists of a single cell, unlike a multicellular organism that consists of multiple cells. Organisms fall into two general categories: prokaryotic organisms and eukaryotic organisms.
Organisms are a biotic, or living, part of the environment. Rocks and sunshine are parts of the non-living environment. An organism is an individual living thing.

Organismer är fysikaliskt strukturerade materiella objekt som till största del består av organiskt kemiska substanser. Dessa objekt har en rad kännetecken som utgör nödvändiga kriterier för liv. Andra ord för organismer är livsformer och kreatur. Organismer har stort inflytande på jordens utseende och sammansättningen av planetens atmosfär.
An organism is defined in a medical dictionary as any living thing that functions as an individual. Such a definition raises more problems than it solves, not least because the concept of an individual is also difficult. Many criteria, few of them widely accepted, have been proposed to define what a

La conducta de los organismos: Un análisis experimental es el primer libro del psicólogo B. F. Skinner.Se publicó en mayo de 1938 como un volumen de la colección Century Psychology Series. [1] En él se establecen los parámetros para el sistema conceptual y metodológico que vendría a llamarse análisis experimental del comportamiento y análisis de la conducta.
Spinoloricus cinziae, a metazoan that metabolises with hydrogen, lacking mitochondria and instead using hydrogenosomes.. An anaerobic organism or anaerobe is any organism that does not require molecular oxygen for growth. It may react negatively or even die if free oxygen is present. In contrast, an aerobic organism (aerobe) is an organism that requires an oxygenated environment.
