A fungus ( plural : ___MASK87___ or funguses ) is any member of the group of eukaryotic organisms that includes unicellular microorganisms such as yeasts and molds , as well as multicellular ___MASK87___ that produce familiar fruiting forms such as mushrooms and bracket ___MASK87___ . These organisms are classified as a kingdom , ___MASK87___ , which is separate from the other eukaryotic life kingdoms of plants and animals . A genus ( genera ) is a taxonomic rank used in the biological classification of living and fossil organisms in biology . In the hierarchy of biological classification , genus comes above species and below family . In binomial nomenclature , the genus name forms the first part of the binomial species name for each species within the genus . Sericomyrmex is a genus of fungus - growing ants in the subfamily ___MASK69___ . The ___MASK69___ are a subfamily within the ___MASK56___ containing ants of moderate evolutionary development . Ants are eusocial ___MASK10___ of the family ___MASK56___ and , along with the related wasps and bees , belong to the order Hymenoptera . Ants evolved from wasp - like ancestors in the Cretaceous period , about 99 million years ago and diversified after the rise of flowering plants . More than 12 , 500 of an estimated total of 22 , 000 species have been classified . They are easily identified by their elbowed antennae and the distinctive node - like structure that forms their slender waists . In biology , an organism is any contiguous living system , such as an ___MASK45___ , plant , fungus , archaeon , or bacterium . All known types of organisms are capable of some degree of response to stimuli , reproduction , growth and development and homeostasis . An organism consists of one or more cells ; when it has one cell it is known as a unicellular organism ; and when it has more than one it is known as a multicellular organism . Most unicellular organisms are of microscopic scale and are thus loosely described as microorganisms . Humans are multicellular organisms composed of many trillions of cells grouped into specialized tissues and organs . Binomial nomenclature ( also called binominal nomenclature or binary nomenclature ) is a formal system of naming species of living things by giving each a name composed of two parts , both of which use Latin grammatical forms , although they can be based on words from other languages . Such a name is called a binomial name ( which may be shortened to just " binomial "), a binomen or a scientific name ; more informally it is also called a Latin name . The first part of the name identifies the genus to which the species belongs ; the second part identifies the species within the genus . For example , humans belong to the genus " ___MASK57___ " and within this genus to the species " ___MASK57___ sapiens ". The " formal " introduction of this system of naming species is credited to Carl Linnaeus , effectively beginning with his work " Species Plantarum " in 1753 . But Gaspard Bauhin , in as early as 1623 , had introduced in his book " Pinax theatri botanici " ( English , " Illustrated exposition of plants ") many names of genera that were later adopted by Linnaeus . Leafcutter ants , a non - generic name , are any of 47 species of leaf - chewing ants belonging to the two genera " ___MASK41___ " and " ___MASK22___ ". These species of tropical , fungus - growing ants are all endemic to South and Central America , Mexico , and parts of the southern United States . The fungus - growing ants ( tribe ___MASK62___ ) comprise all the known fungus - growing ant species participating in ant - fungus mutualism . Leafcutter ants , including " Atta " and " Acromyrmex ", make up two of the genera . ___MASK22___ is a genus of New World ants of the subfamily Myrmicinae . This genus is found in South America and parts of Central America and the Caribbean Islands , and contains 31 known species . Commonly known as " leafcutter ants " they comprise one of the two genera of advanced attines within the tribe ___MASK62___ , along with " Atta ".
