Ulwelwe thanga na ... imizekelo ulwelwe bobukoloniyali, iimpawu zabo nexabiso

Eziphilayo, ikoloni iquka iintlobo ezimbini eziphilayo. Okokuqala, abo ezinama inani elikhulu leseli. Nangona kunjalo, ezi seli ezizo amalungu - imisebenzi yabo ngokwahlukeneyo kakubi kakhulu. Kwakhona, eli qela eziphilayo luphawulwa yokuba iiseli zabo ezingeyo emzimbeni. Kwicandelo elilandelayo - lo mntu eziphilayo ukuba yande kuyo. Abantu kwezi amathanga ezi kweejini efanayo kakhulu, elo thanga kunokuba ezininzi. Izazi zibhekisela kolu hlobo iziponji, neekorale, ulele.

ulwelwe eluhlaza

Ulwelwe thanga baninzi card ulwelwe green. Olu didi yenye ezinkulu Botany - ekuso 20 lamawaka iintlobo ezahlukeneyo .. Inani elikhulu kweentlobo ze ulwelwe eluhlaza aphile kuphela amanzi. Nangona kukho izinto eziphilayo zaselwandle.

ulwelwe Green zimelwe iiklasi ezintlanu. Ezi ziquka volvoxes ebizwa ngokuba yiyo, protococcal kunye ulotriksovye lisiza. Amagama ezi klasi zivela kwisiLatini.

kelp ulothrix

Olu hlobo ixhaphake kakhulu emilanjeni kunye nezinye njengamanzi. Ngokuqhelekileyo lo amathanga igqunyiweyo izinto ezingekho phantsi kwamanzi. Tin yakhiwa kwayo. Ekuqaleni umjikelo awuthathayo kumsonto eqhotyoshelwe noseko lwalo ngokusebenzisa rhizoids - iiseli evuthelweyo. Ulothrix - nwe ulwelwe proliferates ngeendlela ezintathu: ngokwesondo, maqanda kunye kwezityalo. Ezikuyo le uhlobo olwandle nakumanzi fresh. Uhlobo iqhelekileyo ekuthiwa-ulothrix ulothrix belted.

Uhlobo lwesibini zityalwe kwenzeka ngokusebenzisa iiseli ukukhula zoospores - iiseli okweqanda apho zeflagella phambili. Amagatya zoospores emva kokushiya iseli nonina, kangangexesha elithile kusekho ecaleni kwakhe. Emva koko bafumane into kwamanzi, ndizihlalise phezu kwakhe. Entshulayo, zoospores babe abadala.

volvoxes lisiza

nazo volvoxes K Colonial ulwelwe - ulele, umzimba equka iiseli esebenzayo flagellated. Olu hlobo livela neyona abangekaphuhli - ziiamoeba. Ngaphandle kokuba kukho phakathi volvoxes eziphilayo colonial, uninzi zonke enikiweyo single-elilodwa. Yima zombini iindidi ziqulathe 1 engundoqo. Ezi ntlobo ulwelwe ukuzala kwenzeka ngeendlela ezimbini - ngokwesondo asexually. Colonial Volvox ezininzi iiseli lidla limelwe -. Inani labo isusela ukusuka 500 ukuya kuma-60 amawaka ulele na elimile ibhola ububanzi of malunga-2 mm. Ngaphakathi, oko izaliswe yencindi yomlomo. Ukuba silandela intshukumo Volvox koloni, sinako ukubona ukuba ayikho random, kwaye elungelelanisiweyo. Oku kubangelwa yinto yokuba iiseli amaqhina oqhagamshelwano ngokusebenzisa imicu ezizodwa.

Eudorina kunye pandorina - i volvoxes edume

Jonga lona lisiza kunye eliqaqambileyo abameli lobukoloniyali le volvoxes zeklasi - eudorina kunye pandorina. Colony eudorina lubandakanya 32, 64, okanye 128 abantu. Iiseli izinto eyi- amancinci yencindi uqobo enza imilo ukulenza. Pandorina kwakhona ungqukuva ekuveleni koloni. Noko ke, loo nto nayo mobile. Pandorina ngokuqhelekileyo afumaneka kwi ndawo enye eudorina.

Volvox kwemvelo

Volvox - lo ngumzekelo ulwelwe bobukoloniyali, nto leyo eye yaba nempembelelo enkulu kwinkqubo zazivelela. Xa volvoxes kwenzeka ngeendlela ezimbini ezibalulekileyo. Okokuqala, ngo evlyutsii volvoxes uchake umsebenzi leseli eqhelekileyo ngesondo. Njengoko yaziwa, indlela yokugqibela yenye yezinto ezibalulekileyo kakhulu ukuvela eziphilayo multicellular eziphilayo. Le indlela yesibini yendaleko volvoxes - yinto ilahleko kwabo umsebenzi. Le meko iye yakhokelela ekubeni kwakukho zezityalo nezilwanyana.

lisiza protokokki

Ulwelwe thanga nazo protokokki. Ulwelwe - eziphilayo eyingenelo, nto leyo nayo zilinywa umntu kwiimeko ngumntu. Enye iintlobo zokuqala olinywayo zenziwe nje protococcal. Amagama ulwelwe, ezo zisetyenziswa kakhulu kushishino - oko chlorella kunye Scenedesmus. Banda ngendlela fast and kulula - akukho ukuzala, ukukhula ithanga kungenxa ukuyilwa iiseli intombi.

Ulwelwe baphakathi bahlali badala lokuhlala kulo mhlaba. Le fom (kubandakanywa colonial) kubaluleke kakhulu ubomi. ulwelwe yobukoloniyali sele ukwazi ukufunxa imitha yelanga esiwa kumphezulu wolwandle. nabo ukuvelisa izixa ezikhulu into ephilayo. Nabahlali ocean ekuveleni bafumana oksijini carbon dioxide ako ngamathanga. Kananjalo kusetyenziswa, yaye umntu - kwiintlobo kweekhemikhali, amayeza, ngemitha, uqhaqho. ulwelwe yobukoloniyali zeenkunkuma esetyenziswa kwishishini ukuvelisa iiplastiki, ipeyinti, nentlaka, iphepha.
