Ukwakheka Spirogyra - nomele evamile umnyango ulwelwe Green

Spirogyra libhekisela uMnyango ulwelwe oluhlaza. umzimba wayo thallus ukuma filamentous, okuyinto akhiwa amangqamuzana ngamanye futhi akusho akha izicubu izitho. It is a sici nobuntu wonke amalungu eqembu izitshalo aphansi. Ukuze axube base, njengoba kuzo zonke ulwelwe, e Spirogyra babe rhizoids. Ngalezi zokwakheka filamentous thallus enamathiselwe substrate. Rhizoids naye wayemele ekuqongeleleni amaseli bese musa akha izicubu.

Spirogyra okuqondene umnyango ulwelwe Green kunqunywa khona chloroplast e emangqamuzaneni omzimba isitshalo. Letakhi imele umuntu zezintaka plastids. Ngenxa yokuba khona chloroplast ulwelwe, njengazo zonke izitshalo, bayakwazi ukufeza inqubo ye-photosynthesis - carbohydrate self-ukwakha adingekayo ukukhula kanye nokuthuthuka.

Ukwakheka Spirogyra amaseli

Lokhu kuvakashe ummeleli wendlunkulu ulwelwe oluhlaza amaningi. Spirogyra isakhiwo (sibalo ngenhla kubonisa isakhiwo esiyisisekelo) imelelwa isakhiwo filamentous eside. Chloroplast we ulwelwe isimo emapheshana, okuyinto spirally zihambisana. Lesi sici, futhi icacisa igama eziphilayo echazwe. Amaseli nazo side ukuba simise cylindrical. Basuke zixhunywe ikhule ezimbotsheni e nolwelwesi, futhi lapho kwenziwa inqubo umzimba.

Njengazo zonke amaseli isitshalo, iningi labo hlala vacuoles emelela amathangi ogcwele amanzi nezakhi yahlakazeka. Igobolondo elifakwe cellulose carbohydrate, ubanika amandla futhi rigidity.

Alga Spirogyra, njengazo zonke izitshalo, kuyinto umzimba eukaryotic. Lokhu kusho ukuthi amaseli yayo aqukethe i-nucleus. I organelle kuyinto izinhlayiya eziyisisekelo zofuzo eziqukethwe molecule e-DNA.

ukukhahlamezeka kwendawo

Alga Spirogyra e iningi amacala kuyinto owakhileyo angenasawoti zazishintsha zaba nemizimba emi amanzi. Kodwa ahlangana futhi olwandle. ngentambo wakhe, ihlanganisa ngamanani amakhulu, zazinjengoboya oluhlaza, elintantayo phezu.

ukudla

Ukwakheka Spirogyra inquma uhlobo yayo namandla, ngoba amaseli zimumethe oluhlaza ulwelwe chloroplast plastids ukuthi ziyakwazi ye-photosynthesis. essence yayo itholakala kumiswa izinto eziphilayo ukusuka wezinto ezingaphili ngenxa emisebeni yelanga. Lolu hlobo yokudla ngokuthi Autotrophic.

I kwaphumela glucose ulwelwe zisetshenziswa izinqubo ezibalulekile kanye umzimba ukukhula. A Ukukhululwa-mpilo idingwa zonke izinto eziphilayo ngoba emishinini yokuphefumula - isimo ezidingekayo wempilo emhlabeni. Umthombo we izinto ezidingekayo ukuze i-photosynthesis, okungukuthi, amanzi nesikhutha, endaweni yazo ngokuqondile.

ukukhiqizwa kabusha

Ngenxa yalesi alga oluhlaza evelele vegetative esiphelweni izingxenye thallus. imicu eziningi ayahlaselwa izingxenye, ngayinye yaba simenza umzimba omusha. Lokhu kubangela umfutho kanye ukukhiqiza eliphezulu inqubo. Nokho, isakhiwo kwenza kube nokwenzeka Spirogyra futhi inqubo ngokobulili. Uthatha uhlobo conjugation. Ngakho sesigcilikisha ulwelwe kuthiwa okwakuthandelene, imfundo ekhethekile kuphakama therebetween - Isiteshi copulatory. Ngokusho kwalo okuqukethwe yangaphakathi elilodwa yeseli equkethe nesidoda okunikelwe ageleza eya kwenye. Umphumela waba ukwakhiwa uphawu - zygospore. Kuleli zinga, izimila zasolwandle kuletha kwezimo ezingezinhle, futhi entwasahlobo ka likhula ndlovu abasha filamentous.

Inqubo ngokobulili kwenza kube nokwenzeka ukuvela izakhiwo entsha umzimba, okuyinto ebalulekile isitshalo lithathelwe ezishintshashintshayo zendawo eziphila kuyo.

Inani imvelo nempilo yomuntu

Spirogyra isakhiwo kwenza kube into eyinhloko endaweni yokucwaninga ngoba amaseli elikhulu ukuthi ukufinyelela mm 0.01 ububanzi. Lokhu ulwelwe yakha amahlozi obukhulu amadamu amaningi. Lokhu biomass uyakwazi anikezele ngenani ngokwanele ezinkulu oxygen. Kodwa lokhu impahla yenani omubi, njengoba kuholela waterlogging izinqubo zokuwohloka kanye algal blooms. Ngenxa yalokho, izilwane eziningi angase avele afe. Ngokuqinisekile amazwi engoma yezingane "ukusivumela komkhathi brown lasendulo udaka echibini" abazinikele oluhlaza amaqoqo filamentous Spirogyra. Nokho, ngenxa yokuthi uye uyasinda inqwaba impilo yasemanzini, kanye biomass, okuyinto sebakwati, izikhathi eziningana ephakeme kunaleyo izinkomba ezifanayo izitshalo eliwumhlaba.

Spirogyra kuyinto ummeleli evamile iqembu izitshalo aphansi - okungukuthi, uMnyango ulwelwe oluhlaza. Usebenzela kuyingxenye ebalulekile kweMvelo ephelele cishe zakho konke angenasawoti, umthombo udaba eziphilayo ne-oksijini.
