Izicwili Avilable columnar: ulwalamano phakathi isakhiwo kunye nokusebenza

Avilable columnar ijwabu igqabi banoxanduva ukuphunyezwa imisebenzi yayo ebalulekileyo. Nale kwenziwa yonke imisebenzi ebalulekileyo eziphilayo zezityalo. Kweli nqaku siza kujonga iimpawu ezikhethekileyo nokwakheka amalungu le columnar kwithishyu.

Iimpawu yesakhelo sangaphakathi igqabi

Isityalo ibekwe kuxwebhu bar ngelaphu. Njani na lo mzimba? Ukusuka ngaphandle kokuba wambu ngesikhumba. Olu hlobo inshorensi ngelaphu iqulathe ziiseli esinzulu igcwele ophilileyo, phakathi ikuyo le yokondliwa. Ngenxa izakhiwo data enikiweyo kwii-iimolekyuli sukube: ioksijini - kwaba sisityalo, kunye ne-carbon dioxide kunye nomphunga wamanzi - kwicala elahlukileyo.

Phantsi kwesikhumba zibekwe iiseli eziphambili inyama photosynthesis. Ukuba zinkulu, lathamba amalungiselelo, ngoko zenza isiseko sheet. Netheko inkxaso conductive olwenziwa umthambo - iseti lweziqalelo conductive kunye inyama ngoomatshini. Bebonke bakha iinyanda fibrovascular.

I-primary ijwabu igqabi

Eli laphu engundoqo iquka iintlobo iseli ezimbini: columnar kunye ilula. Le yokugqibela i seqanda, kwaye ekhefu phakathi kwabo kwizikhewu intercellular. Ezi zithinteli uthabathe ikota sheet. Elements of eli laphu isiseko izithuba intercellular zenza isiseko ivenkile sheet up izinto ezahlukeneyo ababandakanyekayo kutshintshiselwano igesi. Iimpawu ngesakhiwo yethishyu columnar kwenza isakhiwo engundoqo igqabi photosynthesis.

Column Ilaphu: indawo

Umfanekiso iiseli columnar esiqwini lwegqabi ingakumbi ebonisa indawo yayo. Kubhaliwe ibekwe ngqo phantsi kwesikhumba kwicala aphezulu amagqabi. Kwiiseli ze esiqwini, ngokwenene embhoxo bars, zinokuthi zibekwe kwiindawo omnye okanye ngaphezulu. Eli lungiselelo kungenxa imisebenzi yayo engundoqo - photosynthesis. It elungiselelwe ukufunxeka ioksijini kunye nokukhanya kwelanga.

iimpawu noshowo le columnar inyama

Ibar luhlobo engundoqo nezihlunu kwisityalo. iiseli zayo zezindlu kwimilo, ibekwe ngokuthe nkqo yaye ngokusondeleyo ezikufutshane enye kwenye. Inani kweengqimba izihlunu columnar kuxhomekeke kubungakanani radiation elanga. Ngokomzekelo, xa amagqabi izityalo ezikhula ekukhanyeni, kusenokubakho ezininzi. Uhlobo Umthunzi-ukumelana kule esiqwini ayiqondakali kuphuhliswa.

Umfanekiso iiseli columnar esiqwini igqabi ubonisa isakhiwo zalo ezisisiseko. Le iqokobhe obhityileyo, ngumongo, mitochondria, Golgi ezintsonkothileyo, EPS. Indawo engundoqo kunye isambuku iseli vacuole ohlala. Le kwisisu izaliswe incindi iseli, yinto uhlobo ichibi sonikezelo lwamanzi kunye nezinto ichithwe kuyo. Ngenxa yobukho chloroplasts, iiseli columnar kwithishyu aphuma uhlaza, wamnika kwaye lonke iphepha.

Photosynthesis inokuba iindawo ezahlukileyo zezityalo. Hi xikombiso, le cactus, amagqabi apho reduced enameva, lo msebenzi osemqoka inika Njengokungeniswa kwesithungu yaso. Uyakwazi photosynthesis, yaye abaninzi ezineseli enye eziphilayo: chlamydomonas, oluhlaza euglena, icyanobacteria.

Column Ilaphu: Imisebenzi

iiseli Columnar ziqulathe nani likhulu chloroplasts xa kuthelekiswa namanye iziqalelo laphu isiseko. Ngoko ke, umsebenzi zazo eziphambili - photosynthesis. ukubaluleka kwayo kunganzima ukuba babebiza imali, ngoko yayo idla ngokuba iplanethi yethu.

Le nkqubo nomsi lwenzeka kwi chloroplast inwebu yangaphakathi kuxhomekeke ekufumanekeni kwelanga, icarbon dioxide namanzi. Eziveliswa kule reaction, glucose is a monosaccharide. isityalo yayo esetyenziswa njenge njengomthombo wamandla afunekayo ukuze angakhuli kwaye angaphuhli. Ethungelanayo, glucose yenza carbohydrate starch ezintsonkothileyo. granules yayo ezifakwe reserve xa kukho icytoplasm ngokohlobo inclusions.

Imveliso indlela yesibini photosynthesis ioksijini. Le gas - kuyimfuneko yokuphefumla aerobic, nto leyo ke inkalo ephambili yonke into ephilayo emhlabeni. Undoqo yale nkqubo igcwala kwezinto eziphilayo kunye ukukhululwa amandla neentambo imichiza. iimpawu noshowo inwebu kunye nokubonelela orientation columnar le chloroplasts, nto leyo evumela ukuba imitha yelanga inokubangela mazifakwe ngokufanelekileyo.

Ngoko ke inyama columnar i uhlobo esisiseko. iiseli zawo side imilo zezindlu ilahlwe nkqo ngezantsi sheet isikhumba phezulu. Imisebenzi zeethishu columnar ngenxa neempawu zolwakhiwo: iiseli yaso chloroplasts plastids eziluhlaza nokubonelela flow photosynthesis. Inkqubo lwamaxabiso langa inika iimeko eziphambili ebomini. Ngenxa nezityalo zibonelela izinto eziphilayo, ngenxa apho zixheshiswa, nazo zonke ezinye izinto - oxygen ezifunekayo yokuphefumla.
