Izilwanyana elilodwa

Kweseli imfuyo - udidi eziphilayo, leyo umi ngaphandle nkqubo. Oku kuthetha ukuba akukho sezandleni ngokupheleleyo nayiphi na ubukumkani ethile. kwiseli enye ephawuleka ngokungabikho yeemanyano kakhulu emzimbeni. Zonke izilwanyana yelo qela phakathi kwawo akukho mpawu eqhelekileyo. Ekuphela kwento luwamanyanisa - isakhiwo esilula.

Kweseli izilwanyana ngokuqhelekileyo ezincinane ukuze ingabonwa kuphela phantsi ngemicroscope. endaweni yawo - manzi. Le umhlaba namanzi, kwakunye umzimba womntu, isilwanyana. Bonke bephela indlela enye okanye enye ngoncedo izixhobo ezahlukeneyo ukuze zisebenze kwiimeko ezahlukileyo. Kwindawo yokuqala - yinto uhlobo lomzimba. Maze imida ecacileyo, atshintsha rhoqo, kwaye, phezu koko, kuhlengahlengiswa, njenge osimelela ngentonga okanye evuthelweyo. Neentlobo ezahlukeneyo macala: iphiramidi, translational, ejikelezayo, kabini kabini. Ezinye izilwanyana elilodwa olunye-ukuba iqokobhe ngaphandle, omnye, abo bahlala nzulu ngaphantsi kwamanzi - kweziqu ezingaqhelekanga.

I iseli ukusuka apho umzimba ubunjwe ezi eziphilayo anokuqulatha ukusuka kwelinye ukuya nuclei eziliqela. Shell okanye kuphela inwebu okanye kwintsunguzi, ekwaziyo elide twa pellicle.

Driven kokuphilayo kwiseli enye nge prolegs ezahlukeneyo isiliya, misila. Kwakhona ukusabela nemiphumela yeemeko zangaphandle ezifana notshintsho kwamaqondo obushushu, ukukhanyisa, ukufumaneka lweekhemikhali.

Kweseli izilwanyana ukufumana ukutya ngeendlela ezahlukeneyo. Ngoko ke, ebudeni phagocytosis outgrowths kukho icytoplasm capture amasuntswana esiluqilima ukutya. Pinocytosis ithatha indawo kwizigaba ezininzi: kuqala, le kumphezulu weseli yonke inyathela ulwelo uze nezinto ukufunxa ekuwo, iinkqubo kuzo usebenzisa enzyme, leyo zizaliswe vacuoles. Ngaphakathi kwezinye elula (Chlorella) na chloroplasts ukuba usebenzisa photosynthesis unako ukuvelisa organic evela kwizinto ezingaphiliyo.

Kwakhona, bonke ubuso umzimba ukubandakanyeka elula Exchange igesi: hamba nayo ngaphandle iimveliso yokubola kunye namanzi agqithisileyo.

izilwanyana Qhamani ezineseli kunye ngokwesini, yaye asexually. Kuya kuxhomekeka kwiimeko apho zinqongophele khona. ukuzala maqanda kwenzeka njalo. Okokuqala zahlulo eziliqela nucleus, ilandelwe yi inani elifanayo amaqhosha esahluleleneyo kwaye kukho icytoplasm. Ngenxa yoko, omnye umzimba samabanga wafumana ezininzi (ubuncinane ezimbini).

Xa ukuzala ibandakanya kwamabhinqa namadoda. yesakhiwo ubungakanani zisenokwahluka, kwaye inokuba njalo. Ngenxa naziphi kwakhiwa elilodwa wabo, ngoko leyo iphinde izivelise kwakhona asexually kakade. Kuyenzeka ukuba abantu yahlangana, utshintshiselwano ngamasuntswana nuclei. Kulo mzekelo, i elilodwa ayikho ukusekwa.

Xa iimeko ungakuvumeli kwisiqhelo ubomi obulula, umzimba yabo ngeenxa, ligqunywe iqokobhe ashinyeneyo. Ngoko ke cyst kwakheka. Xa iimeko ngcono, umzimba ekhululwa shinyi umboniso kwaye iqalisa ukuba akhokele yokuphila efanayo ngaphambili.

Kukholelwa ukuba izilwanyana omnye ezineseli yokuqala ukuvela ngexesha zazivelela on Earth. Eyona engunaphakade ke archaea neentsholongwane. Bafana ngeendlela ezininzi (umz, ukungabikho ezingundoqo, ubukho ring chromosome), ngenxa yesi sizathu, ngaphambi kokuba aye athunyelwa kwiqela elinye. Kodwa inzululwazi yanamhlanje iye kubonakele ukuba archaea babe awohluke zabo kubume, yaye waba ngendlela eyahlukileyo kancinane. Nangona nabo kunzima bangahlela, njengokuba ngaphambili. Into yokuba akazange sele elinywa archaea elebhu, waza wafunyaniswa ngexesha ucalulo lwemizekelo athatyathwe iindawo abahlala kuzo.

eziphilayo Single ezineseli - ikhonkco, ngaphandle apho akunakwenzeka ukuba ugcwalise biocoenosis. Ngapha koko, badle izilwanyana ezininzi, nto leyo ngokwabo kuba kukutya nkqu inani kubemi iplanethi yethu.
