parent_taxon glyphaea
___MASK65___ is a flowering plant genus . Traditionally included in the family Sterculiaceae , it is included in the expanded Malvaceae in the APG and most subsequent systematics . These plants are known by a number of vernacular names which sometimes , misleadingly , allude to the superficial similarity of flowering " ___MASK65___ " to pears or hydrangeas ( which are unrelated ). Therefore , the genus as a whole is often simply called dombeyas . The generic name commemorates Joseph Dombey ( 1742  1794 ), a French botanist and explorer in South America , involved in the notorious Dombey affair , embroiling scientists and governments of France , Spain , and Britain for more than two years . Okra or okro ( or ), known in many English - speaking countries as ladies ' fingers , ochro or gumbo , is a flowering ___MASK96___ in the mallow family . It is valued for its edible green seed pods . The geographical origin of okra is disputed , with supporters of West African , Ethiopian , and South Asian origins . The ___MASK96___ is cultivated in tropical , subtropical and warm temperate regions around the world . ___MASK61___ is a subfamily of the Malvaceae family . The group is named after its type genus , " Grewia ", which is named for the English scientist Nehemiah Grew ( 1641 - 1712 ). Glyphaea is a genus of flowering ___MASK96___ in the Malvaceae sensu lato or ___MASK5___ or Sparrmanniaceae family . It contains the following species : Glyphaea tomentosa ___MASK80___ is a genus of about 30 species of trees native throughout most of the temperate Northern Hemisphere . Commonly called lime trees in the British Isles , they are not related to the lime fruit . Other names include linden , and basswood for the North American species . The genus occurs in Europe and eastern North America , but the greatest species diversity is found in Asia . Under the Cronquist classification system , this genus was placed in the family Tiliaceae , but genetic research summarised by the Angiosperm Phylogeny Group has resulted in the incorporation of this genus , and of most of the previous family , into the Malvaceae . Endosperm is a tissue produced inside the seeds of most of the flowering plants following fertilization . It surrounds the embryo and provides nutrition in the form of starch , though it can also contain oils and protein . This can make endosperm a source of nutrition in the ___MASK81___ diet . For example , wheat endosperm is ground into flour for bread ( the rest of the grain is included as well in whole wheat flour ), while barley endosperm is the main source of sugars for beer production . Other examples of endosperm that forms the bulk of the edible portion are coconut " meat " and coconut " water ", and corn . Some plants , such as orchids , lack endosperm in their seeds . The gymnosperms are a group of seed - producing plants that includes conifers , cycads , " ___MASK34___ ", and gnetophytes . The term " gymnosperm " comes from the Greek composite word "  " (  gymnos , " naked " and  sperma , " seed "), meaning " naked seeds ", after the unenclosed condition of their seeds ( called ovules in their unfertilized state ). Their naked condition stands in contrast to the seeds and ovules of flowering plants ( ___MASK29___ ), which are enclosed within an ovary . Gymnosperm seeds develop either on the surface of scales or leaves , often modified to form cones , or at the end of short stalks as in " ___MASK34___ ". Cotton is a soft , fluffy staple fiber that grows in a boll , or protective case , around the seeds of the cotton plants of the genus " ___MASK38___ " in the family of " Malvaceae ". The fiber is almost pure cellulose . Under natural conditions , the cotton bolls will tend to increase the dispersal of the seeds . Sparrmanniaceae is a segregate ___MASK96___ family , containing plants which have more commonly been classified in Malvaceae or ___MASK5___ . In the most recent proposed circumscription , that of Cheek ex Heywood et al ., it corresponds to subfamily ___MASK61___ of the APG family Malvaceae . In botany , a fruit is the seed - bearing structure in flowering plants ( also known as ___MASK29___ ) formed from the ovary after flowering . ___MASK57___ , or the mallows , is a family of flowering plants estimated to contain 244 genera with 4225 known species . Well - known members of this family include okra , cotton , and cacao . The largest genera in terms of number of species include " ___MASK47___ " ( 300 species ), " Sterculia " ( 250 species ), " Dombeya " ( 250 species ), " Pavonia " ( 200 species ) and " Sida " ( 200 species ). ___MASK5___ is a botanical name for a family of flowering plants . It is not a part of the APG , APG II and APG III classifications , being sunk in Malvaceae but has an extensive historical record of use . ___MASK24___ is a genus of flowering plants in the mallow family , Malvaceae . It was previously placed in the now obsolete Sterculiaceae . Members of the genus are colloquially known as tropical chestnuts . The scientific name is taken from Sterculius of Roman mythology , who was the god of manure ; this is in reference to the unpleasant aroma of the flowers of this genus ( e . g ., " ___MASK24___ foetida "). Sperm is the male reproductive cell and is derived from the Greek word (  ) " sperma " ( meaning " seed "). In the types of sexual reproduction known as anisogamy and its subtype oogamy , there is a marked difference in the size of the gametes with the smaller one being termed the " male " or sperm cell . A uniflagellar sperm cell that is motile is referred to as a spermatozoon , whereas a non - motile sperm cell is referred to as a spermatium . Sperm cells cannot divide and have a limited life span , but after fusion with egg cells during fertilization , a new organism begins developing , starting as a totipotent zygote . The ___MASK81___ sperm cell is haploid , so that its 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell . In mammals , sperm develops in the testicles and is released from the penis . It is also possible to extract sperm through TESE . Some sperm banks hold up to of sperm . A flower , sometimes known as a bloom or blossom , is the reproductive structure found in plants that are floral ( plants of the division ___MASK58___ , also called angiosperms ). The biological function of a flower is to effect reproduction , usually by providing a mechanism for the union of sperm with eggs . Flowers may facilitate outcrossing ( fusion of sperm and eggs from different individuals in a population ) or allow selfing ( fusion of sperm and egg from the same flower ). Some flowers produce diaspores without fertilization ( parthenocarpy ). Flowers contain sporangia and are the site where gametophytes develop . Many flowers have evolved to be attractive to animals , so as to cause them to be vectors for the transfer of pollen . After fertilization , the ovary of the flower develops into fruit containing seeds . The flowering plants ( ___MASK29___ ), also known as Angiospermae or ___MASK58___ , are the most diverse group of land plants , with 416 families , approx . 13 , 164 known genera and a total of c . 295 , 383 known species . Like gymnosperms , ___MASK29___ are seed - producing plants ; they are distinguished from gymnosperms by characteristics including flowers , endosperm within the seeds , and the production of fruits that contain the seeds . Etymologically , angiosperm means a plant that produces seeds within an enclosure , in other words , a fruiting plant . The term " angiosperm " comes from the Greek composite word (" angeion ", " case " or " casing ", and " sperma ", " seed ") meaning " enclosed seeds ", after the enclosed condition of the seeds . A botanical name is a formal scientific name conforming to the " International Code of Nomenclature for algae , ___MASK52___ , and plants " ( ICN ) and , if it concerns a plant cultigen , the additional cultivar and / or Group epithets must conform to the " International Code of Nomenclature for Cultivated Plants " ( ICNCP ). The code of nomenclature covers " all organisms traditionally treated as algae , ___MASK52___ , or plants , whether fossil or non - fossil , including blue - green algae ( Cyanobacteria ), chytrids , oomycetes , slime moulds and photosynthetic protists with their taxonomically related non - photosynthetic groups ( but excluding Microsporidia )." ___MASK47___ ( or ) is a genus of flowering plants in the mallow family , Malvaceae . The genus is quite large , comprising several hundred species that are native to warm - temperate , subtropical and tropical regions throughout the world . Member species are renowned for their large , showy flowers and are commonly known simply as ___MASK47___ , or less widely known as rose mallow . The genus includes both annual and perennial herbaceous plants , as well as woody shrubs and small trees . The generic name is derived from the Greek word  (" hibískos "), which was the name Pedanius Dioscorides ( ___MASK35___ . 40  90 ) gave to " Althaea officinalis ".
