Kwihlabathi kukho izinto ezininzi ezimangalisayo ezincinane. Ukuba umntu weza intloko yam uluhlu imisebenzi ezisixhenxe sekuba, i Volvox lisiza ngokuqinisekileyo ziqukiwe kolu luhlu.

ulwelwe eluhlaza

Volvox - a lisiza eluhlaza. Zikhona ngohlobo ngamathanga. Kutheni Volvox obizwa ngokuba elilodwa olunye-? Impendulo icebisa ngokwayo ilula: zonke single Ingca yolwandle encinane kwaye iseli eye misila amabini ke neenwele.

iiseli Abangatshatanga idityaniswe imisonto ubhityileyo kukho icytoplasm kunye namanye, oluvumela butho ukuqubha ngazwinye. abameli ngabanye ngaphandle iinwele kunye misila kwakhona kwaba litshatshazi encinane ebomvu, ebizwa ngokuba amehlo.

iseli kuphakanyiswa unika abameli ulwelwe ekhethekileyo. koloni nganye elinesiqalo kunye nesiphelo, ngamanye amazwi, izibonda eMntla naseMzantsi. Kwingingqi lokuqala uye wabona olwenzeka ngokukhawuleza ngakumbi amathupha zaphuhliswa. Oku kunceda nobulembu ukudada ekukhanyeni. Ngenxa yoko, ithanga eziphilayo olunye-ezineseli imbonakalo unokucanda kakuhle ukuba omzimba multicellular.

Volvox: isakhiwo

Xa bebuzwa ukuba kutheni Volvox wabhekisela eziphilayo njengoko ezineseli-elinye, kufanelekile ukuba sikhankanye ukuba iseli enye kunokuba ukuya ku-2 omise ubukhulu (kumathanga ezinkulu - up to 2 cm), ngoko ke kulula kunokubonwa ngeliso lenyama. Ezinye ulwelwe idityaniswe zixhobo ubhityileyo kukho icytoplasm.

Volvox ulwelwe babe isakhiwo ngokwanelisayo elula. Komgodi central ezaliswe yencindi yomlomo. Zonke cell misila amabini, nto leyo ziqhotyoshelwe ekupheleni ngaphambili. iseli ngalinye esiseleni lenza umsebenzi wayo isondlo, nokuphefumla kunye zinomgutyulo. Imilo inokuba ungqukuva, okweqanda, okanye elimbhoxo. Umaleko engaphandle kwakhona ehlanganiswa yi yencindi yomlomo. Iseli nganye neso elilodwa kwi indlela yechaphaza kwi ekupheleni ngaphambili.

buphindwe

ulwelwe Volvox ukuzala iindlela ngendlela enomdla kwaye inika umdla. Bayakwazi ziyazala zombini asexually nangezifo. Lapho sihlolisisa ungabona ukuba inkoliso amathanga na kwiindawo ezithile, ezo zibizwa ngokuba gonads.

Olu luphawu yokuzalana maqanda. Gonads evela kwiiseli ezikhuliselwe ngeenxa zonke ikhweyitha le koloni. Ezi seli bekhula kwaye afumane uthotho iyantlukwano de ukwenza amacandelo amancinane. Kulo mzekelo, i zeflagella ngaphakathi kwisangqa entsha. Ukususa kubo, iseli umele uvule wena ngaphakathi ngaphandle.

Volvox uyakwazi zizalana ngokwabo njengoko ngokwesini. Like yokuzala maqanda baziqwebele iiseli ezikhethekileyo ehlabathini ikhweyitha. amathanga oyindoda kwakunye nomntu obhinqileyo iiseli ezahlukeneyo lwegciwane.

amadlozi akhiwa hlula. Female iiseli sex musa yahlula; kwandisa nje ubukhulu. eziphilayo abaninzi ingamadoda amathanga ababhinqileyo. Abanye hermaphrodites.

Volvox kunye nokukhanya kwelanga

Ukuqwalasela amaqela amathanga ngemicroscope ukukhanya a emehlweni emangalisa ngokwenene. Ukuba ushiya isithuba esaneleyo phantsi le chap ukuba isiliphu, amacandelo okuluhlaza okuncinane aqale ukuba zidade iza ilayithi.

Volvox Kulula kakhulu ukufumana. Bonke ke kufuneka - nto intle acocekileyo kunye namanzi ashushu, esisityebi ngezakhi. A ixesha kuhle ukuba bagcine - ehlotyeni. Scooping up mbelukazi oluhlaza ezimbalwa kunokubonwa yibhanki amanzi "ichibi eqhubela" lisiza iya bangezi ekukhanyeni.

yokuhlala

Kutheni Volvox obizwa ngokuba elilodwa olunye-? Kodwa nantsi eyona nyaniso. Volvox has isakhiwo ezineseli enye-, singabinakho zodwa geqe, ngoko ngokufuthi kwenza amathanga ungqukuva abantu ukuya ku-50 000. Yinto nje iseli omzimba ngemikroskopu. Oku kwenzeka iinkqubo zayo ebalulekileyo. Yiyo loo nto Volvox wabhekisela eziphilayo nje elinye-elilodwa.

yokuhlala efanelekileyo kwezi lona lisiza ngamanzi ahlaziyekileyo. Ezi amagciwane zifumaneka amachibi, izisele nkqu emachibini kuyaphi. Volvox ulwelwe ziphakathi indala kakhulu kwiplanethi yethu. Ngokutsho imibono wenzululwazi, ngendlela bobukoloniyali yobomi, kwakunjalo kwiminyaka million 200 eyadlulayo.

Volvox - eziphilayo ahambele phambili hlobo. Yenza i ungqukuva, ellipsoid okanye ikoloni ovoid. Iiseli ekuveleni ziqulethe yiklorofili, ngoko bona ngokwabo ukunika ukutya iphotosynthesis. iseli ngalinye ubenzela okulungileyo kweli thanga, bavele kunye abe eyodwa.
