Yintoni na le yokondliwa: iimpawu isakhiwo nokusebenza

Amagqabi a kwicala kumalungu esityalo, okwenza ibalulekileyo umsebenzi zezulu sonikezelo kunye negesi exchange. Ithuba ukuphunyezwa izinto ezinxulumene iinkalo ubume kwimakhishithi, enye yona yokondliwa. Ngoncedo lwabo, izityalo kunye ukuphefumla, kunye osha amanzi. Yintoni na yokondliwa, ziziphi iimpawu yesakhiwo umbutho, sichaza ngokweenkcukacha kwinqaku lethu.

Nokuphefumla kunye photosynthesis

Zonke izinto eziphilayo, kuquka izityalo, bayakwazi umoya. Oku kwaziwa kakuhle yinto yokuqala efunekayo ukuze ubukho babo. kubume bayo siyifumana ukufunxeka ioksijini, igcwala kwezinto eziphilayo kunye ukwahlulwa carbon dioxide. Kodwa iplanethi ukubaluleka zezityalo sikuko ekuqhubeni abhalwe inkqubo - photosynthesis. Ekuhambeni layo, i-carbon dioxide ako neoksijini efunekayo zonke izinto eziphilayo, kuvezwe. Izityalo bayakwazi ukwenza le nkqubo ezimbini ngexesha elinye ngegalelo lazo kubangelwa ubukhulu becala ukuba umsebenzi lo yokondliwa, eziphezu komhlaba sheet.

Ubume yokondliwa

Yintoni stoma? It is a uhlobo pores ibekwe ukutyabeka esiqwini sesityalo, ekuthiwa Ulobuza. Izitomata ke advantageously zidityaniswe iiseli sembotyi-ezimile. iindonga yabo edyokhweni anquma kwiindawo ezahlukeneyo. Phakathi iiseli yokondliwa stomatal ibekwe lokuvula. Therethrough kwizisele izityalo ngokwangaphandle yabelwe izinto ezahlukeneyo sukube. Iiseli stomatal Binary bayakwazi ukutshintsha imilo zabo, apho ubukhulu umsantsa phakathi kwabo ukuze inyuswe okanye ihliswe. Oku kukhokelela ummiselo ubunzulu wotshintshiselwano igesi kwisityalo.

Iimpawu ze ukusebenza yokondliwa

Ukuba kunjalo, yintoni na yokondliwa, siyakuqonda, oku ukuba senze noko ixhomekeke, thina kodwa ukuze ufunde indlela. iiseli Guard uyakwazi ukutshintsha imilo ngokuxhomekeke kwisixa lamanzi. Ukuba le into kwisityalo kakhulu, bona adumbe, ukwandisa ngobukhulu yaye kude komnye. Stomatal uqhoqhoqho ngokwendalo kwandisa. Le nqubo yokuchaza igesi uba namandla. Amanzi agqithisileyo lukhutshwa umsantsa, ngumphunga, nesityalo akukho shushu ngokugqithisileyo ngexesha eshushu.

Transpiration kakhulu kakhulu kwakhona ukuba ukunyuka kwamaqondo obushushu umoya kunye nokomeleza amandla omoya. Kwimeko esahlukileyo, ukufuma xa ayikho indlela inyathelo iiseli labalindi ezahlukeneyo ngokwaneleyo. Zihlanganiswe ngokusondeleyo namanye, kunye noqhoqhoqho stomatal ophela nje, nto leyo ethintela ekuphunyezweni kwenkqubo ye komphunga amanzi. Ngenxa yoko, isityalo angalahlekelwa ukufuma iimeko nokusilela.

indawo yokondliwa

Njengoko sele kukhankanyiwe, lo yokondliwa - eseqweqweni sisityalo ophilayo isakhiwo kwithishyu. Ibizwa ngokuba Ulobuza. Kwisityalo elise, kwiimeko ezininzi, kwicala kumazantsi sheet. Olu hlobo ukhuseleko kwimitha ngqo. Kwakhona kule meko intle walondoloza egciniweyo amanzi kwi plant cells. Kodwa hayi zicwangciswe onke amagqabi tye. Hi xikombiso, le irises ukuba rostut nkqo. Ngoko ke, lo yokondliwa zisasazwe macala onke amagqabi.

Le meko yahlukile kwimeko yezityalo emanzini. Inxalenye esezantsi amagqabi akufunekanga ibe yokondliwa. Ngapha koko, antywiliselwa ngokupheleleyo emanzini yaye, ke ngoko, akayi kuba nako ukwenza imisebenzi yabo. Le yokondliwa ze izityalo kwi kumphezulu amagqabi. Inani labo mkhulu ngokwaneleyo, njengoko kwelinye sentimitha sikwere kwiphepha - up to eziliqela amashumi amawaka kwiziseko ezinjengezo.

Plants ngaphandle yokondliwa

Kwaye ezinye izityalo evinjwa yokondliwa. Umzekelo, Elodea walamba ukuntywiliselwa ngokupheleleyo emanzini, ngoko, ukuba abanakuzeyisa. Kwaye nokuba kunjalo ukuya yokondliwa kwaye apho, wenze imisebenzi yabo akunakwenzeka. Eyona nto kukuba amanzi aqukuqela aye umsantsa, yenziwe ngaphandle kokunika inkqubo Exchange igesi.

yokondliwa intsingiselo

Izitomata zifumaneka kwi -inshorensi ngelaphu, ngoko umsebenzi wabo engundoqo nethe kumzimba kokusingqongileyo. Enye yazo amanzi inkqubo ngumphunga kuthiwa transpiration. Ukuphunyezwa kwawo kubaluleke kakhulu ukuqinisekisa ukuba izityalo musa shushu ngokugqithisileyo ngexesha eshushu, kuba oko kunokukhokelela ekufeni kwabo. Xa Ukuvela komphunga luhlobo ekubizwa yokondliwa ezingathandekiyo waphantse wayeka transpiration, ngokwenjenjalo egcina fuma kuyimfuneko.

Kodwa gymnosperms wenzile a okhethekileyo yelungiselelo yokondliwa. Bona kwakugcwele ebusika nentlaka okhethekileyo. Ngoko ke, onke amalungu eSebe zizityalo enehlathi. Akukho mfuneko yokuba eshedini zabo namagqabi bazikhusele bazibeka kakhulu ukufuma ebusika. Ngokwahlukileyo koko, kuzo zonke ezi angiosperms kuhlala bezinzile kweli xesha kuphela kukusindisa kwaye ingcambu. Kodwa bawe amagqabi, ukuze kuphulukana unikezelo lwamanzi ukwenzela ubusika. Ngoko ke, umthi weKrismesi "ebusika yaye ehlotyeni umbala omnye."

Yintoni na yokondliwa, zisebenza njani kwaye ukwenza imisebenzi yabo, siye sahlolisisa ezinye iinkcukacha. Nangona kunjalo, oku kufuneka wathi ukongeza transpiration, bakhonza nabo njengeyunithi ezikhethekileyo ioksijini kwinkqubo zokuphefumla kuyenzeka kunye neerisithi yekharboni dayokhsayidi yefotosinthesisi. Ukongeza, le yokondliwa bayakwazi ukulawula ngobunzulu zonke ezi nkqubo, nto leyo kuxhomekeke kwizinto zangaphandle, kwaye wabonakaliswa ukuze zikwazi ukumelana kuzo zonke izinto eziphilayo eziguqukayo ngokukhawuleza iimeko zokusingqongileyo.

Ngenxa yoko, kwiphepha nesigqubuthelo ngelaphu yimfundo ezizodwa, ebizwa yokondliwa. Ziqulethe iiseli yabalindi yokubini kwaye umsantsa phakathi kwabo. Enkosi kwi Umsebenzi walo isakhiwo zenziwa kwiinkqubo ezibalulekileyo umzimba isityalo komphunga amanzi, photosynthesis kunye nokuphefumla.
