Ulwakhiwo Spirogyra - ungummeli obabuthandwa isebe lona lisiza Green

Spirogyra ibhekisa kwiSebe lisiza eluhlaza. Umzimba wayo simise thallus filamentous, nto leyo ubunjwe iiseli ngamnye kwaye aluyiyo ancedisana amalungu. Kuba isici uphawu onke amalungu eqela yezityalo eziphantsi. Kuba ezinamathela isiseko, njengoko zonke ulele, e Spirogyra babe rhizoids. Ngezi namabandla filamentous thallus eqhotyoshelwe kule zeendawana. Rhizoids emelwe zemali iiseli kwaye ezizo emzimbeni.

Spirogyra yelo sebe lo lisiza Green emiselwe ubukho chloroplasts xa iiseli zomzimba izityalo. Ezi zithinteli imele uhlobo olunye plastids. Ngenxa yobukho chloroplasts ulwelwe, njengazo zonke izityalo, bayakwazi ukwenza inkqubo photosynthesis - carbohydrate self-yakheka ezifunekayo ukukhula kunye nophuhliso.

Ulwakhiwo iiseli Spirogyra

Le ummeli lona lisiza eluhlaza i omzimba multicellular. isakhiwo Spirogyra (nani ngasentla ibonisa isakhiwo esisiseko) limelwe isakhiwo elide filamentous. Chloroplasts ze lona lisiza babe ngohlobo ngezithandelo, ezithi isongelwe spirally. Lo msebenzi, kwaye ikhankanya igama eziphilayo ezichazwe. Iiseli nazo side ukuba imilo zezindlu. Bona eziqhagamshelene pores kwi inwebu, yaye apho kwenziwa inkqubo ukutya.

Njengazo zonke iiseli zezityalo, uninzi lwabo nokuhlala vacuoles emele amatanki ezaliswe ngamanzi kunye nezondlo lichithakale. Shell buzane neselulosi ekudleni, wabanika amandla nokoma.

Ubulembu Spirogyra, njengazo zonke izityalo, i omzimba eukaryotic. Oku kuthetha ukuba iiseli yaso nucleus. Le organelle na umbandela genetic eziqulethwe iimolekyuli DNA.

yokuhlala

Nobulembu Spirogyra kwi uninzi macala nammi kwamaziko amatsha amanzi umi. Kodwa yena uhlangana no elwandle. intambo yakhe, baluka kumanani amakhulu, njengoboya bezimvu eluhlaza, kwakudada phezu komhlaba.

ukudla

Ulwakhiwo Spirogyra igqiba uhlobo namandla alo, kuba iiseli ziquka eluhlaza ulwelwe chloroplasts plastids ukuba ziyakwazi photosynthesis. kubume bayo siyifumana ukuyilwa kwezinto eziphilayo ukusuka ezingaphiliyo ngenxa radiation elanga. Olu hlobo lokondla ekuthiwa autotrophic.

I-glucose ulwelwe kubangele ziyasetyenziswa iinkqubo ebalulekileyo kunye nokukhula eziphilayo. A release mpilo ifunwa zonke izinto eziphilayo yokuphefumla - imeko kukho imfuneko yobukho emhlabeni. Umthombo izinto eziyimfuneko ifotosinthesisi, oko kukuthi, amanzi kunye carbon dioxide, nto ngqo kwiindawo zazo zokuhlala.

buphindwe

Kuba lo nobulembu eluhlaza lubalaseleyo andise kwezityalo iindawo thallus. Imisonto amaninzi uwaphule lwagabuka, ngasinye ezinokukhokelela ekuchithekeni omzimba entsha. Oku kubangela umfutho kunye nemveliso ephakamileyo inkqubo. Noko ke, isakhiwo kwenza kube lula Spirogyra kunye nenkqubo ngokwesini. Uthabatha uhlobo conjugation. Ngaloo zixhobo ulwelwe uyahambelana, imfundo ezizodwa kuvela therebetween - channel copulatory. Ngokutsho kuyo imixholo lwangaphakathi kwiseli enye equlathe genetic material amdaka ukuya kwenye. Isiphumo ukuyilwa evaliwe - zygospore. Kule meko, Ingca yolwandle kuzisa iimeko ezinzima, kunye entwasahlobo kwayo lukhula ndlovu abaselula filamentous.

Inkqubo ngesondo yenza kunokwenzeka ukuvela iimpawu ezintsha lomzimba, nto kubalulekile ukuba izityalo ukuziqhelanisa neemeko zokusingqongileyo ukutshintsha.

Ixabiso semvelo kunye nobomi babantu

isakhiwo Spirogyra kwenza kube ke into ephambili elabhoratri kuba has a iiseli elikhulu ukuba zifike 0,01 mm ubukhulu. Le ulwelwe kwenza iintshinyela ezishinyeneyo kwi okugcina amanzi amaninzi. Le biomass uyakwazi isixa esikhulu ngokwaneleyo ioksijini. Kodwa lo mhlaba esinentlawulo engenaxabiso, njengoko kukhokelela zokuxinana kwamanzi iinkqubo yokubola ekuveleni esezansi. Ngenxa yoko, izilwanyana ezininzi afe nje. Ngokuqinisekileyo amazwi engoma yabantwana "ukusivumela isibhakabhaka brown of kwakheka yamandulo zodaka" abazinikele ezisebenzisanayo eluhlaza filamentous Spirogyra. Nangona kunjalo, ngenxa eliphila inani elikhulu ubomi emanzini, kunye biomass, ekungekho bakwazi ukwakha, izihlandlo eziliqela ngaphezulu Iimpawu ezifanayo zezityalo nezilwanyana.

Spirogyra ngummeli wendlela iqela izityalo ephantsi - oko kukuthi, iSebe lisiza eluhlaza. Inceda kuyinxalenye yentlanganisela eziphila kuzo phantse yonke yamanzi, umthombo mba organic neoksijini.
