Sibaluleke coelenterates indalo. Yintoni ukubaluleka coelenterates kwindalo nakubomi

Nangona iimpawu ilula lwesakhiwo, ixabiso coelenterates iyafika buqapheleke kakhulu. Inani lilonke bale hlobo ukuya amawaka 10 iintlobo up. Ezahlukeneyo eziphila zabo - ukusuka amatsha encinane ukuya elwandle imingxuma enzulu-elwandle. Yintoni na le sibaluleke ngokwemvelo coelenterates, ngamafuphi kwinqaku lethu.

Imvelaphi yegama

Ezi zilwanyana multicellular kwazenzekela ukuba igama unit taxonomic. Inyaniso kukuba i-ini babe sayo isisu, apho ukwetyisa ukutya. Ungene kuwo emlonyeni usebenzisa nemisipha. iiseli ezizodwa glandular iienzymes sokugaya em- umzimba, leyo eyenzeka phantsi kwempembelelo inkqubo ekugayeni.

yeempawu ezibonakalayo

coelenterates intsingiselo kwindalo kunye nobomi babantu luqinisekiswa kakhulu izinto awohluke yesakhiwo. Kuqala kwinto zonke, ezi ezimbini umaleko umzimba: lwangaphandle nangaphakathi. Ziqulethe iiseli ezikhethekileyo. Ngalinye iintlobo owenza imisebenzi ethile. EsiPhakathi ngokucandeka akhokhelele ukuba iiseli ezintsha, luvo odityanisiweyo ephilayo integrally ukuba nolwalamano yayo kunye nokusingqongileyo. Makubulelwe ke iiseli ulusu-izihlunu coelenterates nga nciphisa ukuze ukugoba kunye nesihamba ngayo.

"Lwalawo" coelenterates ezi ziiseli ehlabayo. Bona ise umaleko zangaphandle umzimba. Ezi seli luqulathe capsule ngaphakathi apho kukho msonto ephothiweyo ukuba isiphelo elibukhali. Ngaphandle iseli iinwele onovakalelo. Xa umntu echukumise umntu sesaa ngalinye womsonto amandla ukumba emzimbeni yexhoba. Xa oku wangena, yaye into ityhefu. Alinako kuphela bungabi, kodwa kunokukhokelela ukufa eziphilayo.

angenawo hydra

coelenterates intsingiselo kwindalo kunye nabantu kungathathwa kwi umzekelo ummeli eqhelekileyo - hydra. Le ephilayo ezincinane kwikhonkco kwikhonkco lokutya. Kakade ke, Qhotsa intlanzi, bona bengekho; ngokuba afakwe isikhuni iiseli ehlabayo. Kodwa kwezilwanyana vetvistouhih amanyathelo kwabo ayikho eyoyikekayo, ngoko zisitya phezu nezihlunu olu hlobo coelenterates. Umphezulu umzimba ngamanzi na indawo yokuhlala efanelekileyo xa iintlobo ezahlukeneyo ciliates.

Ukufunyanwa nesifundo iimpawu ze isakhiwo hydra yaba nqanaba ebalulekileyo kuphuhliso KABLOOM. Amalinge ebandakanya le ephilayo yaba bubungqina ukuba ukuchacha kunye nokungakwazi ukuba inkqubo ngokwesini na iimpawu zazo zahluke. Igama hydra wanika ngunozala KABLOOM uKarl Linney. Wayebhekisela umlinganiswa eponymous wentsomi ngubani ngokukhawuleza wabuyisa iintloko ikhanda. Amanzi hydra kwakhona kuchaphazela ukukwazi kwabo ukuntshula. Kunokuba ukululama ngokupheleleyo yinxalenye 1/200!

Hydra esusa amanzi avela amasuntswana organic ekubeni zeBRT lokucoca yendalo.

ukutsha kakhulu

Yintoni ukubaluleka coelenterates kwindalo, siye ingqalelo kancinane. Wonke umntu walixhoba iiseli jellyfish abuhlungu, kufuneka sibe nomdla kulo mba. Bona zibekwe phezu kweentsimbi zabo kunye kwisisu ngomlomo. Intlanganiso ezininzi kwezi kungenzeka ibe engakhuselekanga.

Xa kumalwandle tropical kumiwa yi ithanga wenqanawa Portuguese. Ityhefu iiseli zabo abuhlungu ebangela umntu ukutsha kakhulu, iintlungu, ukuphazamiseka kwisingqi zokuphefumla umsebenzi intliziyo. Ukuba ixesha ayiboneleli uncedo kumaxhoba, isiphumo lunokubulala. Njengoko yingozi kwaye abahlali kwimimandla esemantla: Bukanomeva ulwandle kunye tsianeya.

Kwimeko ukutsha kakhulu kufuneka zisuswe eluswini sesaa iiseli usebenzisa isisombululo inkqubo ammonia izihlunu sisilonda esidumbileyoesingaphakathi, utywala okanye soda. Ukuba negalelo akomelela, kufuneka ngoko nangoko udibane nogqirha.

jellyfish

yamaHindu bukhanye jellyfish, ngokungafaniyo polyp bayakwazi ukuba ngenkuthalo ukuhamba. Ba ezizingelayo ezithile, preying phezu ezingenamqolo kunye nentlanzi. Ezinye iintlobo ze jellyfish bayakwazi jet basafunda. Abanye, ezifana zaselwandle kunye nezinye isibane kancinane ukugaqa ukusuka kwenye indawo ukuya kwenye.

Yintoni na ke sibaluleke ngokwemvelo coelenterates phambili yokuphila yeselula? Ngokwendalo, oku yi candelo ebalulekileyo ebalulekileyo eziphila elwandle nezidanga ukutya.

Ngaphandle iintlobo enetyhefu ngokwendalo uyabazi yaye ezityiwayo. Kumazwe amaninzi aseAsia, ukuba uju oyithandayo.

Kanye hydra, jellyfish efanele zezilwanyana zovavanyo. Isixhobo ekwaziyo yokuqikelela iinyikima zomhlaba, izaqhwithi, nesiphango, yenzelwe isekelwe kubume ezi zidalwa yolwandle.

angangenwa

Ukubaluleka kwindalo coelenterates kwakhona umdla ukuqwalasela umzekelo koloni kwelekorale. Ngembonakalo, bona zifana na isilwanyana, indlela yokuphila ngakumbi ukuba ziqhotyoshelwe. Phinda-phinda amagqabi, lo Buze engumphumela gqiphu kude. Ngenxa yoko, isakhiwo wafumana iimilo ethelekelelwayo. enza lwabo lwangaphakathi abunjwe ngecalcium carbonate okanye izinto eziqinileyo organic.

Coral polyp anemone kufana intyatyambo kumnandi eliqaqambileyo. Inkoliso yabo yokuphila yokuphanga, preying phezu molluscs ezincinane, intlanzi kunye nentlanzi. Kukho kwakhona mdla lokucoca ulwelo. anemones ezinjalo ukondla ukuba amanzi lisiza, iintsholongwane lenyama. Kodwa ke, nabo sokwenza umsebenzi olongezelelweyo - amanzi acocekileyo.

ndlu ehamba

Yintoni na ke sibaluleke ngokwemvelo coelenterates, uyazi ncam enomzimba yedwa. Kwaye akukho ngokupheleleyo a joke. Eyona nto kukuba akakwazi khona nje kungekho lo mhlaza liqhubu. Actinium, ke, ufumana yokutyiwa zokutya somhlaza kwaye uthi njengendlela yokuhamba. Ukutshintsha iqokobhe, nokufakelwa isilwanyana kuyo kunye liqhubu yakhe. Kwaye ngengqiqo emitsha yelizwi. Yena icala iinzipho anemone, ngoko ndarhubuluza kwindawo entsha. Nantsi i elimangalisayo win-win "kubudlelwano".

Qaphela: izixhobo

Eyona nto ibaluleke ngokukodwa xa kujongwa uhlobo coelenterates lezixhobo. Le thanga enkulu polyp, inani labantu ukuba efikelela izigidi. I inkulu kwezi Enkulu Barrier Reef, leyo eqhubeka kunxweme Australia i-Pacific Ocean.

Oku kumiswa yendalo yokuhlala iintlobo ezininzi ulele, intlanzi, izilwanyana, iintshulube kunye nentlanzi. Kumazwe island yimvula lonxweme, abantu abaqokelelana izixhobo izityalo yolwandle ezityiwayo kunye nezilwanyana. A lekalika zingafumaneka kwamathambo izixhobo, zisetyenziswa wokwakha. Ekubeni coral zakha into eqinileyo kakhulu, bona ukukhusela unxweme nomsinga iziqithi kukhukuliseko. Ngenxa kwisibheno ubuhle imihombiso ezi zenziwa, impahla yendlu, zezikhumbozo. Abaphengululi abaninzi bakholelwa ukuba ubomi kwisiqithi esincinane yetropika bekuya kuba yinto nje akunakwenzeka ngaphandle izixhobo. yonke indawo imveliso ophezulu bemvelo ecosystem yendalo kwamanzi, oonobangela apho oosonzululwazi baye kodwa uku bana phandle.

Enkosi iimpawu zazo eyodwa isakhiwo kunye neentlobo ezahlukeneyo enexabiso coelenterates indalo kubaluleke kakhulu kwaye imisela indima yabo enkulu yendalo nazo kulo mhlaba.
