Glucose is a simple sugar with the molecular formula CHO . Glucose circulates in the blood of animals as blood sugar . It is made during photosynthesis from water and carbon dioxide , using energy from sunlight . The reverse of the photosynthesis reaction , which releases this energy , is an important source of power for cellular respiration . Glucose is stored as a polymer , in plants as starch and in animals as glycogen , for times when the organism will need it . 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 . The western honey bee or European honey bee (" ___MASK27___ ") is the most common of the 7 - 12 species of honey bee worldwide . The genus name " Apis " is Latin for " bee ", and " mellifera " means " honey - bearing ", referring to the species ' tendency to produce a large quantity of honey for storage over the winter . 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 " Homo " and within this genus to the species " ___MASK51___ ". 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 . Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in humans , animals and ___MASK79___ . The polysaccharide structure represents the main storage form of glucose in the body . Nectar is a sugar - rich liquid produced by plants in glands called nectaries , either within the flowers with which it attracts pollinating animals , or by extrafloral nectaries , which provide a nutrient source to animal mutualists , which in turn provide antiherbivore protection . Common nectar - consuming pollinators include mosquitoes , hoverflies , wasps , bees , butterflies and moths , hummingbirds , and bats . Nectar plays an important role in the foraging economics and overall evolution of nectar - eating species ; for example , nectar and its properties are responsible for the differential evolution of the African honey bee , " A . m . scutellata " and the western honey bee . Honey / hni / is a sweet food made by bees using nectar from flowers . The variety produced by honey bees ( the genus Apis ) is the one most commonly referred to , as it is the type of honey collected by most beekeepers and consumed by people . Honeys are also produced by bumblebees , stingless bees , and other hymenopteran insects such as honey wasps , though the quantity is generally lower and they have slightly different properties compared to honey from the genus Apis . Honey bees convert nectar into honey by a process of regurgitation and evaporation . They store it as a primary food source in wax honeycombs inside the beehive . Honey gets its sweetness from the monosaccharides fructose and glucose , and has about the same relative sweetness as granulated sugar . It has attractive chemical properties for baking and a distinctive flavor that leads some people to prefer it over sugar and other sweeteners . Most microorganisms do not grow in honey because of its low water activity of 0 . 6 . However , honey sometimes contains dormant endospores of the bacterium Clostridium botulinum , which can be dangerous to infants , as the endospores can transform into toxin - producing bacteria in infants ' immature intestinal tracts , leading to illness and even death . People who have a weakened immune system should not eat honey because of the risk of bacterial or fungal infection . No evidence shows any benefit of using honey to treat diseases . Providing 64 calories in a typical serving of one tablespoon , honey contains no significant essential nutrient content . Honey is generally safe but there are various , potential adverse effects or interactions it may have in combination with excessive consumption , existing disease conditions or drugs . Honey use and production has a long and varied history . Honey collection is an ancient activity . Humans apparently began hunting for honey at least 8 , 000 years ago , as evidenced by a cave painting in Valencia , Spain .
