Coelenterates Uhlobo: iimpawu ngokubanzi

Enye amaqela yokuqala zezilwanyana multicellular - lohlobo Coelenterates. Grade 7, equka izifundo ngezilwanyana ehlola ngokweenkcukacha zonke iimpawu noshowo ezi zidalwa ezimangalisayo. Makhe kwakhona ukukhumbula into ayiyo.

Chwetheza Coelenterates: Biology

Name iyunithi ngendlela yezi izilwane ngenxa isakhiwo kwegama elifanayo. Ibizwa ngokuba kwisisu isisu, kunye nabameli zayo zonke iintlobo: polyp kunye esa ebomini ezikhuselekileyo, kwaye ngenkuthalo ezihambayo jellyfish. Iimpawu ezifana coelenterates njengoko ubukho iiseli ezikhethekileyo. Kodwa nangona balo msebenzi phambili ubume umzimba yezi zilwanyana aluyiyo ezi iithishu.

yokuhlala nokuphakwa

Le yokuqala yezi zilwanyana multicellular inokufumaneka amanzi kunye netyiwa imimandla zemozulu ezahlukileyo. Chwetheza Coelenterates (7 iklasi yesikolo olubanzi kwezinye ngokweenkcukacha wasikhangela sifundo) kwaye imelwe iisampulu ezincinane ububanzi of a iimillimitha ezimbalwa, kwaye jellyfish ingxilimbela kunye nemisipha elide ukuya kwiimitha ezili-15. Ngoko ke, lo uhlobo dama, bahlala apho, ingaba nomahluko. Ngoko ke, amanzi hydra ezincinane ezihlala kumadama ezincinane, kunye polyp zibe ngamathanga enkulu elwandle emvula.

Coelenterates Uhlobo: iimpawu ngokubanzi

Umzimba siquka zonke coelenterates iintlobo iseli eziliqela, iyileyo ezisebenza umsebenzi ethile, efana imizimba nzima amalungiselelo izilwanyana.

Uphawu ezingundoqo coelenterates - kuba phambi iiseli ehlabayo. Ziqulethe capsule apho ekumsonto ephothiweyo ukuba isiphelo elibukhali. iiseli Top na iinwele onovakalelo. Xa athe wachukumisa umzimba ixhoba, ngoko esijikelezayo kwaye glares kwi lamandla ayo. Ngenxa yoko, oko kube nempembelelo paraliziruyuschee. Emva koko, usebenzisa abameli Mpondwana yolu hlobo obekwe umbingelelo sayo emathunjini. Kwaye inkqubo ukwetyisa lomba ephilayo iqala apha. Kwaye ukuba amncede enze iiseli yokwetyisa kunye glandular.

Coelenterates uhlobo ebonakala iqondo eliphezulu kutsha. Izazinzulu lubonise ukuba hydra amatsha nga angachacha ngokupheleleyo emzimbeni inxenye 1/200. Kwaye mhlawumbi oku ngenxa yobukho iiseli aphakathi. Ezimisele, isishiya zonke ezinye iintlobo. Coelenterates kwaye ezinako ukuzala ngokudibana amaqanda amadlozi.

iiseli zemithambo saa kuwo wonke umzimba, ekuqhubeni ulwalamano kunye okusingqongileyo kwaye luhlanganisa zibe yinto enye. Ngoko, ke umdla kakhulu intshukumo enye abameli coelenterates - hydra. Ngenxa umsebenzi ulusu kunye izihlunu iiseli bafana Acrobat, ukusuka entloko ukuya kuphela, nto leyo ngoku somersault.

iinkqubo kubalulekile coelenterates

Coelenterates hlobo lubonakala ngokuba amalungu ngxuba ababengaphambi zabo - protozoans kunye iziponji. Nangona kukho iimpawu ezifanayo. Umzekelo, exchange igesi kusaqhubeka ngokusebenzisa kumaqweqwe, kunye nezakhiwo ezikhethekileyo oku bengekho.

Ngenxa iiseli ulusu-izihlunu, jellyfish bayakwazi jet basafunda. Oku kunciphisa intsimbi zabo, amanzi zityhalelwa ngamandla, ebangela enotyhalo umva.

Zonke coelenterates zizilwanyana karhataka. Ukususa Mpondwana ngomlomo engena emzimbeni. Ukusebenza kwenkqubo kukwahlukana ngexesha elinye kwaba ubukho iintlobo ezimbini ukwetyisa: ukusetshwa zeselula.

Kuba coelenterates luphawulwa ubukho impendulo ephilayo ukuba uvuselelo - ingqondo. Bathi ukuphendula neziphumo koomatshini okanye imichiza yokusingqongileyo kuvela. A jellyfish babe zemfundo ezizodwa ezibuthathaka ngokubonelela imali eseleyo umzimba, kunye imbono yokukhanya lokugcina.

umjikelezo

Chwetheza Coelenterates linophawu kukuba uninzi lweentlobo zayo kumjikelo wobomi kukho alternation ngezizukulwana. Umzekelo, liqhubu Aurelia iphindaphindeka kuphela asexually nge lolu. Ekuhambeni kwexesha, umzimba womnye kubo wahlulwe constrictions ezinqamlezayo. Ngenxa yoko, kukho jellyfish amancinci. Ngokweliso, bakhangeleka ngathi esitoreni amacwecwe. Ngabanye ukuba kuza off phezulu uye nokuphila elizimeleyo kunye esebenzayo.

Alternating coelenterates Isizukulwana wobomi ngokwesondo kunye maqanda ikhuthaza ukunyuka ngokukhawuleza kwenani kwaye kakuhle zabo chithwa ngolunya.

Ibandakanya uhlobo iiklasi Coelenterates, polyp nje anamathela. Zakha nwe iimilo engaqhelekanga. Le coral polyp. Akukho alternation kwizizukulwana nahambayo hydra. Bona zizalana ngokuthi yavelisa amagqabi ehlotyeni nasekwindla ukuya ukuzala, size sife. La maqanda ivundiswe ukuchitha ubusika emazantsi okugcina amanzi. Kwaye entwasahlobo ka hydra wabo ekuphuhliseni abaselula.

A ezahlukeneyo coelenterates

Coelenterates Chwetheza kwindalo bubonakaliswe eziphilayo ezimbini: polyp kunye jellyfish. Enye abameli ezininzi umdla iqela lokuqala actinium. Le mmi kweelwandle efudumeleyo lemvula, leyo, ngenxa umbala oqaqambileyo, ikhangeleka ngathi intyatyambo kumnandi. Ngenxa yoko, igama lesibini actinium - anemones yolwandle. Phakathi kwazo kukho mdla filter eziyingozi. Kwaye ezinye iintlobo anemones yolwandle unako ukungena okusoloko kuyinzuzo co-ubukho kunye oononkala yedwa.

Iqhubu ubuchule ukuhambahamba adle iintsalela arthropods ukutya organic. Iseli umhlaza ikhuselekile anemones ulwandle ehlabayo. Okubangel 'umdla kukuba, ukutshintsha amaxesha ngamaxesha ukucwila, thombo apho liqhubu. Umhlaza icala iinzipho anemone, nokuyishiya yodwa akhasa yaba ikhaya elitsha.

A ikoloni polyp zenze cluster enkulu. Umzekelo, i-Great Barrier Reef zinabela kunxweme ka-Australia phezu umgama omalunga 2 amawaka km.

coelenterates kwindalo kunye nobomi babantu Meaning

coelenterates abaninzi kunokuba yingozi kwezilwanyana nabantu. Usebenza iiseli zabo abuhlungu ebangela nokutsha. neziphumo zazo ukuze umntu abe amahlaba, intloko ebuhlungu, ukuphazamiseka zentliziyo kunye namaziko zemiphunga. Ukuba akukho xesha, kunye nokufa kunokwenzeka.

Iipolyps kunye jellyfish zinendima ebalulekileyo chain yonikezelo abemi lwamanzi. A coral kumazwe amaninzi asetyenziswa ekwenzeni izacholo, njengezikhumbuzo kunye nezinto zokwakha.

Ngoko ke, uhlobo Coelenterates, iimpawu ngokubanzi ukuba kwaxoxwa, limelwe eziphilayo ezimbini. It iipolyps kunye jellyfish. Ezi zilwanyana luphawulwa ulingano iphiramidi, ubukho iiseli ezizodwa kunye alternation izizukulwana lomjikelo wobomi.
