Avilable kwezicubu columnar: ubudlelwano phakathi lokuphatselene nesakhiwo nemsebenti

Avilable columnar leaf izicubu banesibopho ukuqaliswa kwemisebenzi yayo ebalulekile. Nale kwenziwe yonke imisebenzi ebalulekile umzimba isitshalo. Kulesi sihloko sizohlola izici ehlukile ye nokwakheka zomzimba we columnar izicubu.

Izici Sakhiwo sangekhatsi leaf

Lesi sitshalo itholakala ishidi ibha Indwangu. lo umzimba kanjani? Kusukela ngaphandle ke embozwe isikhumba. Lolu hlobo ikhava Indwangu siqukethe amaseli enqwabelene ophilayo, phakathi lapho stomata zitholakala. Ngenxa izakhiwo idatha enikeziwe Ukungena zishintshe gaseous: - mpilo ngibe sitfombo, ne-carbon dioxide futhi umhwamuko - kolunye uhlangothi.

Ngaphansi isikhumba zitholakala main photosynthesis izicubu amaseli. Ziyakwazi ezinkulu, alengayo ahlelwe, ngakho zakha isisekelo ishidi. Futhi conductive ukweseka umsebenzi wenziwa umthambo - iqoqo izakhi conductive futhi izicubu lokukhanda. Bebonke bakha izinyanda fibrovascular.

Okuxhunyanwa leaf izicubu

Indwangu main siqukethe izinhlobo cell ezimbili: columnar futhi isipanji. Lesi sakamuva une-kobujamo obusaqanda, futhi ngezikhathi phakathi kwabo kukhona izikhala intercellular. Lezi zakhiwo zithatha ingxenye yesine ka ishidi. Imisuka base Indwangu izikhala intercellular yisisekelo ishidi esitolo kuze izinto abathintekayo igesi exchange. Izici isakhiwo kwezicubu columnar ukwenza kube isakhiwo eyinhloko iqabunga photosynthesis.

Ikholomu Indwangu: indawo

UMdwebo amaseli columnar ihlamvu kwezicubu ikakhulukazi sibonisa indawo yayo. Itholakala ngqo ngaphansi kwesikhumba ohlangothini engenhla amaqabunga. Amaseli ijwabu, ngempela okusikhumbuza nemigoqo, zingafakwa endaweni eyodwa noma eziningi imigqa. Leli lungiselelo kungenxa imisebenzi yayo eziyisisekelo - photosynthesis. It elungiselelwe ukumuncwa oksijini elangeni.

izici isakhi columnar izicubu

Ibha uhlobo main izicubu simila. amaseli zako ziyizindlela cylindrical isesimweni, isebangeni thwi futhi eduze eduze komunye nomunye. Isibalo izingqimba kwezicubu columnar incike ukushuba emisebeni yelanga. Ngokwesibonelo, e amaqabunga izitshalo ezimila ukukhanya, kungase kube eziningana. Uhlobo umthunzi-ukubekezela kule izicubu ayiqondakali athuthukile.

UMdwebo amaseli columnar ihlamvu izicubu ubonisa isakhiwo kwayo okusemqoka. Lokhu igobolondo nomzimba omncane, i-nucleus, mitochondria, Golgi eziyinkimbinkimbi, EPS. Zisendaweni ephakathi futhi ingxenye enkulu yomsebenzi vacuole cell ithatha. Lokhu ingaphakathi ligcwele ijusi cell, it is a uhlobo kwesigubhu ngoba amanzi kanye nezinto ziyoncibilika kuwo. Ngenxa yokuba khona chloroplast, amaseli columnar kwezicubu kuluhlaza, simenze kanye ishidi.

Photosynthesis kungenzeka izingxenye ezahlukene zezitshalo. Ngokwesibonelo, cactus, amaqabunga awo kwehliswa kwameva, lesi sici ihlinzeka Isiqu esinamanzi. Onekhono ye-photosynthesis, futhi abaningi eziphilayo owumphumela: chlamydomonas, oluhlaza euglena, cyanobacteria.

Ikholomu Indwangu: Imisebenzi

amaseli columnar aqukethe inani elikhulu chloroplast e ngokuziqhathanisa nomunye izakhi base Indwangu. Ngakho-ke, umsebenzi wabo oyinhloko - photosynthesis. ukubaluleka kwalo kungabhekwa neze overestimated, ngakho nobukhulu bayo uvame ukubizwa ngokuthi kwamaplanethi.

Le nqubo photochemical kwenzeka kwi kwangaphakathi chloroplast ulwelwesi kuncike ukutholakala ukukhanya kwelanga, isikhutha namanzi. Imikhiqizo okunjena, glucose kuyinto monosaccharide. isitshalo yayo isetshenziswa njengenhlangano umthombo namandla adingekayo ukukhula nokwakheka kwalo. Iboshwe, glucose yakha eziyinkimbinkimbi carbohydrate isitashi. elimbudumbudu bakhona imali zigciniwe ku cytoplasm ngesimo inclusions.

Eyesibili ukuphendula umkhiqizo photosynthesis mpilo. Lokhu igesi - imfuneko kwezimila aerobic, okuyinto isici esiyinhloko zonke izinto eziphilayo emhlabeni. Ingqikithi yale nqubo iyona namachibi izinto eziningi eziphilayo nge ukukhululwa kwe amandla izibopho zamakhemikhali. izici isakhi kwezicubu unikeze orientation columnar we chloroplast, ebavumela ukuba imisebe yelanga ingabangela libanjwe kahle.

Ngakho izicubu columnar uhlobo eziyisisekelo. amaseli bakhona side ukuma cylindrical futhi ngokufanele thwi ngezansi phezulu isikhumba ishidi. Imisebenzi izicubu columnar ngenxa izici kwesakhiwo: amaseli yayo aqukethe chloroplast plastids eluhlaza ukunikeza ukugeleza-photosynthesis. Inqubo yamanani kwamaplanethi inikeza izimo eyinhloko ekuphileni. Ngenxa yalokho izitshalo zayo ukunikeza udaba eziphilayo, ngenxa okuyinto ezidla, kanye nazo zonke ezinye izinto eziphilayo --mpilo kwadingeka kwezinhlelo kwezimila.
