In biology, an organism from Greek, organismos is any individual entity that exhibits the properties of life. It is a synonym for life form. Organisms are classified by taxonomy into specified groups such as the multicellularanimals, plants, and fungi or unicellularmicroorganisms such as a protists, bacteria, and archaea. All types of organisms are capable of reproduction, growth and development, maintenance, and some degree of response to stimuli. Humans are multicellular animals composed of many trillions of cells which differentiate during development into specialized tissues and organs. An organism may be either a prokaryote or a eukaryote. R U S E Money Hack. Prokaryotes are represented by two separate domainsbacteria and archaea. Eukaryotic organisms are characterized by the presence of a membrane bound cell nucleus and contain additional membrane bound compartments called organelles such as mitochondria in animals and plants and plastids in plants and algae, all generally considered to be derived from endosymbiotic bacteria. Fungi, animals and plants are examples of kingdoms of organisms within the eukaryotes. Estimates on the number of Earths current species range from 1. More than 9. 9 of all species, amounting to over five billion species,5 that ever lived are estimated to be extinct. In 2. LUCA of all living organisms living was identified.

There is a long tradition of defining organisms as self organizing beings, going back at least to Immanuel Kants 1. Critique of Judgment. DefinitionseditAn organism may be defined as an assembly of molecules functioning as a more or less stable whole that exhibits the properties of life. Dictionary definitions can be broad, using phrases such as any living structure, such as a plant, animal, fungus or bacterium, capable of growth and reproduction. Many definitions exclude viruses and possible man made non organic life forms, as viruses are dependent on the biochemical machinery of a host cell for reproduction. A superorganism is an organism consisting of many individuals working together as a single functional or social unit. There has been controversy about the best way to define the organism1. Several contributions2. Non cellular lifeeditViruses are not typically considered to be organisms because they are incapable of autonomous reproduction, growth or metabolism. This controversy is problematic because some cellular organisms are also incapable of independent survival but are capable of independent metabolism and procreation and live as obligatory intracellular parasites. Although viruses have a few enzymes and molecules characteristic of living organisms, they have no metabolism of their own they cannot synthesize and organize the organic compounds from which they are formed. Naturally, this rules out autonomous reproduction they can only be passively replicated by the machinery of the host cell. In this sense, they are similar to inanimate matter. While viruses sustain no independent metabolism, and thus are usually not classified as organisms, they do have their own genes, and they do evolve by mechanisms similar to the evolutionary mechanisms of organisms. The most common argument in support of viruses as living organisms is their ability to undergo evolution and replicate through self assembly. Some scientists argue that viruses neither evolve, nor self reproduce. In fact, viruses are evolved by their host cells, meaning that there was co evolution of viruses and host cells. If host cells did not exist, viral evolution would be impossible. This is not true for cells. If viruses did not exist, the direction of cellular evolution could be different, but cells would nevertheless be able to evolve. As for the reproduction, viruses totally rely on hosts machinery to replicate. The discovery of viral megagenomes with genes coding for energy metabolism and protein synthesis fueled the debate about whether viruses belong in the tree of life. The presence of these genes suggested that viruses were once able to metabolize. However, it was found later that the genes coding for energy and protein metabolism have a cellular origin. Most likely, these genes were acquired through horizontal gene transfer from viral hosts. ChemistryeditOrganisms are complex chemical systems, organized in ways that promote reproduction and some measure of sustainability or survival. The same laws that govern non living chemistry govern the chemical processes of life. It is generally the phenomena of entire organisms that determine their fitness to an environment and therefore the survivability of their DNA based genes. Organisms clearly owe their origin, metabolism, and many other internal functions to chemical phenomena, especially the chemistry of large organic molecules. Organisms are complex systems of chemical compounds that, through interaction and environment, play a wide variety of roles. Organisms are semi closed chemical systems. Although they are individual units of life as the definition requires, they are not closed to the environment around them. To operate they constantly take in and release energy. Autotrophs produce usable energy in the form of organic compounds using light from the sun or inorganic compounds while heterotrophs take in organic compounds from the environment. The primary chemical element in these compounds is carbon. The chemical properties of this element such as its great affinity for bonding with other small atoms, including other carbon atoms, and its small size making it capable of forming multiple bonds, make it ideal as the basis of organic life. It is able to form small three atom compounds such as carbon dioxide, as well as large chains of many thousands of atoms that can store data nucleic acids, hold cells together, and transmit information protein. MacromoleculeseditCompounds that make up organisms may be divided into macromolecules and other, smaller molecules. The four groups of macromolecule are nucleic acids, proteins, carbohydrates and lipids. Nucleic acids specifically deoxyribonucleic acid, or DNA store genetic data as a sequence of nucleotides. The particular sequence of the four different types of nucleotides adenine, cytosine, guanine, and thymine dictate many characteristics that constitute the organism. The sequence is divided up into codons, each of which is a particular sequence of three nucleotides and corresponds to a particular amino acid. Thus a sequence of DNA codes for a particular protein that, due to the chemical properties of the amino acids it is made from, folds in a particular manner and so performs a particular function. These protein functions have been recognized Enzymes, which catalyze all of the reactions of metabolism. Structural proteins, such as tubulin, or collagen. Regulatory proteins, such as transcription factors or cyclins that regulate the cell cycle. Signaling molecules or their receptors such as some hormones and their receptors. Defensive proteins, which can include everything from antibodies of the immune system, to toxins e.
