This list of Latin and Greek words commonly used in systematic names is intended to help those unfamiliar with classical languages to understand and remember the scientific names of organisms. The binomial nomenclature used for animals and plants is largely derived from Latin and Greek words, as are some of the names used for higher taxa , such ...
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
The term "organism" (from the Ancient Greek ὀργανισμός, derived from órganon, meaning ' instrument, implement, tool ', ' organ of sense ', or ' apprehension ') [2] [3] first appeared in the English language in the 1660s with the now-obsolete meaning of an organic structure or organization. [3] It is related to the verb "organize". [3]
Latin names of organisms are generally used in English without alteration, but some informal derivatives are used as common names. For example, the -idae ending of subclass names is changed to -ids (e.g., Rosidae produces rosids); the subfamily ending -oideae is changed to -oids (e.g., Papilionoideae produces papilionoids).
The word animal comes from the Latin noun animal of the same meaning, which is itself derived from Latin animalis 'having breath or soul'. [6] The biological definition includes all members of the kingdom Animalia. [7] In colloquial usage, the term animal is often used to refer only to nonhuman animals.
A small fraction of the genes in an organism's genome called the developmental-genetic toolkit control the development of that organism. These toolkit genes are highly conserved among phyla, meaning that they are ancient and very similar in widely separated groups of animals. Differences in deployment of toolkit genes affect the body plan and ...
The term can also be used to refer to the study of the entirety of an organism's lifespan. Ontogeny is the developmental history of an organism within its own lifetime, as distinct from phylogeny, which refers to the evolutionary history of a species. Another way to think of ontogeny is that it is the process of an organism going through all of ...
The generic epithet Pseudomonas was coined by Walter Migula in 1894, who did not give an etymology. [1] [2] Since the 7th edition of Bergey's manual (=top authority in bacterial nomenclature), other authors have given the etymology to be: Greek pseudēs (ψευδής, false) and monas (μονάς, single unit or monad), which can mean "false ...
