Venation Parallel: Iinkalo ngesakhiwo izityalo

Parallel venation amagqabi zifumaneka kwindalo rhoqo ngokwaneleyo kwaye zibalulekile yokuhlelwa zezityalo. Kuba abathile eziphilayo, oko ekuso yaye ziziphi iimpawu zayo, siza kuxubusha ngayo kwinqaku namhlanje bethu.

Yintoni venation

Uluhlu - sakhiwo lubalulekileyo kwisityalo, enza imisebenzi ebalulekileyo. Okokuqala kwaye kwephambili ekuqondeni inkqubo transpiration nangefotosinthesisi. Izinto ezo akhiwa ngexesha elinye, udlulele inkqubo okhethekileyo sheet. Le yingqokelela izinto ilaphu conductive okanye, ngendlela elula, imithambo. Zingakotshwa amalungiselelo ngendlela eyahlukileyo. Uhlobo indawo yabo wabiza mibala.

iintlobo venation

Kukho iindidi ezintathu ezingundoqo venation. Le umnatha, arc kunye ngaxeshanye. Kwaye ngokwendalo kukho unxulumano olucacileyo phakathi imilo ibe likhaba esegqabini kunye nohlobo indawo yegazi. Khawucinge ngomzekelo oku kuxhomekeka nezityalo ezimbalwa eqhelekileyo. Umzekelo, palchastye amagqabi maple ziye asasaze venation, apho esiqhumeni engundoqo nemithambo ifiber ohluka ngokucacileyo. Suka nobuzwe imiyalelo wesibini nowesithathu. La malungiselelo efanayo okufana cherry, oningga, rose, soy, iimbotyi, iitapile, tomato, ikhaphetshu kunye nezinye dicots ezininzi. Xa amagqabi yomgama ukwakha isakhiwo eyahlukileyo kwinkqubo Uhanjiso. Ukuba ndlela iphambili awabelwa, kwaye ezikufutshane ukusuka kuxwebhu base ukusuka kwenye indawo ye jike, uze uqhagamshele phezulu layo, lo mzekelo uhlobo yesibini. Kuyinto eqhelekileyo, umzekelo, inyibiba entilini kunye ngeplantain. mibala Parallel kwakhona kwenzeka xa amagqabi yomgama.

sheet venation Okhunye

Kakade ukusuka igama kucacile ukuba ngemithambo amagqabi zicwangciswe ngaxeshanye omnye komnye. Awabonisi kusukwa kwipleyiti ecaleni kwawo. venation ukufana i uphawu monocots. Ezi ziquka amalungu ezininzi yentsapho okuziinkozo, itswele kunye weenyibiba. Edge ye yabe igqabi nje niya kuxhaxhwa, kwaye tyaba ngokupheleleyo, ukuze kube lula ofanayo ehlelwe mithambo.

Izityalo kunye venation ukufana

Kwakhona venation parallel kuba monocot Uphawu yi kukho umbungu Cotyledon omnye, Iingcambu ezinezikhondo, ukunqongophala yethishyu cambial e esiqwini, amagqabi lobufazi. Phakathi kulo iiyunithi ingca eqhelekileyo ecwangcisiweyo, ubuncinane - kwetyholo.

Ezibalulekileyo ngokoqoqosho ngokukodwa phakathi kwazo ezi zityalo nengca okanye bluegrass. Umbona, ingqolowa, irye, nerhasi, irayisi - zonke cereals ezaziwayo. Isingqengqelo ingca, Kentucky bluegrass, uTimoti, brome zizityalo emathafeni eqhelekileyo ezo ngokugqibeleleyo apha naphaya ukulungiselela iimeko ikhephu ebusika encinane ukubanda nobushushu zasehlotyeni owomileyo. Phakathi ukutya okuziinkozo, yaye ezininzi izityalo ezixabisekileyo wefula.

Xa njengenyibiba, exabisekileyo zityalo zokuhombisa nobusi, kukho kwakhona kukho abameli mibala ngaxeshanye. Sinaye ukuguqulwa ebalulekileyo ukubaleka ngokufihlakeleyo - itswele. Ukusebenzisa data bakhe ngokukha ngokutyalwa izityalo idluliselwe nembalela kunye namaxesha 'amazinyo.

Kabanzi kwindalo netswele. Kakhulu, bona kukhula basike clearings ehlathini. Enkosi kwi iibhalbhu, baye bakwazi ukuba zikhona kweemeko emaqeleni, amathafa neentlango.

Ngoko ke zifana mibala ngokuqhelekileyo abameli leklasi of monocots. Olu hlobo lungiselelo wetshati izinto conductive zimelwe iinyanda fibrovascular apho zicwangciswe ecaleni kwipleyiti amagqabi yomgama.
