Mtundu Coelenterates: makhalidwe ambiri

Limodzi la magulu loyamba la nyama multicellular - lembani Coelenterates. Kalasi 7, limene lili Inde zinyama ikufotokoza mwatsatanetsatane mbali zonse structural cha zolengedwa zodabwitsa. Tiyeni kamodzinso kukumbukira zomwe iwo anali.

Lembani Coelenterates: Biology

Dzina mwadongosolo unit wa nyama chifukwa cha Kapangidwe ka dzina chomwecho. Njirayi imatchedwa M'mimbamo matumbo, ndi nthumwi zake ndi mitundu yonse: tizilombo ting'onoting'ono ndi kutsogolera moyo wotetezedwa, ndipo mwachangu akusuntha modabwitsa. Makhalidwe monga coelenterates monga kupezeka kwa maselo apadera. Koma ngakhale mbali kusintha kwa zinthu Kapangidwe ka thupi la nyama si kupanga zimakhala izi.

malo ndi deployments

Izi woyamba wa nyama multicellular angapezeke mu madzi atsopano ndi mchere wa mabacteria osiyana nyengo. Lembani Coelenterates (7 kalasi ya sukulu mabuku mwatsatanetsatane ikufotokoza nkhani) ndi ukufanizidwa ndi toyesa ang'ono ndi awiri a millimeters ochepa, ndi modabwitsa chimphona ndi tentacles yaitali mpaka mamita 15. Choncho, chikhalidwe cha posungira, kumene amakhala, angakhale osiyana. Choncho, ang'onoang'ono madzi oyera hydra moyo m'madamu ang'ono, ndi tizilombo ting'onoting'ono matanthwe kupanga madera ambiri m'nyanja otentha.

Mtundu Coelenterates: makhalidwe ambiri

thupi imakhala coelenterates zonse mitundu yambiri selo, omwe amachita ntchito yeniyeni, monga matupi zolimba anakonza nyama.

Khalidwe lalikulu la coelenterates - ndi kukhalapo kwa maselo lobaya. Iwo zigwirizana wa kapisozi imene ulusi wopota ndi mapeto lakuthwa. Top maselo tcheru tsitsi. Pamene wokhudza thupi la munthu ochitiridwayo, ndiye amanena ndi glares pa mphamvu zake. Chifukwa, iwo ali paraliziruyuschee amadza. Kenako, ntchito tentacles oimira mtundu aikidwa nsembe lumen wa matumbo. Ndi ndondomeko ya chimbudzi cha organic wayamba pano. Komanso kumuthandiza kugwira maselo m'mimba ndi glandular.

Coelenterates mtundu yodziwika ndi digiri yapamwamba ya kusinthika. Asayansi asonyeza kuti hydra madzi oyera ingathandize achire thupi la 1/200 gawo. Ndipo mwina ndi chifukwa kukhalapo kwa maselo wapakatikati. Iwo mwachangu nawo, kuti pakhale mitundu yonse ena. Coelenterates ndipo atha kubereka kudzera pophatikizana mazira ndi umuna.

maselo mitsempha anamwazikana thupi lonse, pochita ubale ndi chilengedwe ndi kaphatikizidwe kukhala coherent lonse. Choncho, n'zochititsa chidwi kwambiri ndi kayendedwe ka mmodzi wa oimira coelenterates - hydra. Chifukwa cha ntchito ya khungu ndi minofu maselo ngati Acrobat ndi, kusuntha kuchokera kumutu mpaka yekha, kupanga tsopano linatembunuka.

kwambiri m'thupi coelenterates

mtundu Coelenterates amakhala ndi Maphunziro Akakhalidwe Kazolengedwa zovuta kuposa akapolo anzawo akale - protozoans siponji. Ngakhale pali zizindikiro zofanana. Mwachitsanzo, mpweya kuwombola akadali kudutsa chimakwirira, ndi nyumba apadera uyu ali kwina.

Chifukwa cha maselo a khungu-minofu, modabwitsa angathe ndege zosagwiritsa. Izi amachepetsa belu awo, madzi anakankhira ndi mphamvu, kuchititsa Kankhani iwowo.

coelenterates onse nyama zolusa. Ndi tentacles m'zigawo kudzera pakamwa umalowa thupi. Mwachangu za ndondomeko akuwaza nthawi yomweyo anatsimikizira kukhalako mitundu iwiri ya chimbudzi: M'mimbamo ndi ma.

Pakuti coelenterates yodziwika ndi pamaso pa chamoyo poyankha kukondoweza - bongo. Yak poyankha zotsatira makina kapena mankhwala chilengedwe. modabwitsa A nawo maphunziro apadera tcheru kupereka chingakuthandizeni thupi, ndi maganizo a kuwala.

mayendedwe amoyo

Lembani Coelenterates komanso yodziwika ndi chakuti ambiri a mitundu zake kayendedwe ka moyo pali kusinthana kwa mibadwo. Mwachitsanzo, polyp Aurelia yekha kuchulukana asexually kudzera budding. M'kupita kwa nthawi, thupi mmodzi wa iwo sagwirizana chifukwa cha kaduka yopingasa. Chifukwa, pali waung'ono modabwitsa. Zowoneka, amaoneka ngati mulu wa mbale. Mmodzimmodzi wa iwo anabwera kuchokera pamwamba ndi kupita ku moyo palokha ndi akuchitachita.

Alternating kugonana ndi asexual m'badwo lifecycle coelenterates amalimbikitsa kuwonjezeka mofulumira chiwerengero ndi zosavuta awo kufalitsa.

Kumaphatikizapo lembani Coelenterates makalasi, ndi tizilombo ting'onoting'ono si lamamatira. Iwo apanga chambiri akalumikidzidwa chodabwitsa. Izi tizilombo ting'onoting'ono matanthwe. Palibe kusinthana kwa mibadwo ndi madzi oyera hydra. Iwo kubereka ikuphukira m'chilimwe ndi yophukira kupita kubereka, kenako n'kumwalira. The mazira ndi umuna m'nyengo yozizira pansi pa madamu. Ndipo m'chaka cha awo osauka hydra wamng'ono.

A zosiyanasiyana coelenterates

Mtundu Coelenterates m'chilengedwe ukufanizidwa ndi zamoyo ziwiri: tizilombo ting'onoting'ono ndi modabwitsa. Imodzi mwa oimira chidwi kwambiri a gulu loyamba ndi actinium. wokhala izi mwa nyanja ofunda otentha, amene, chifukwa cha mtundu owala, amaoneka ngati maluwa wosangalatsa. Choncho, dzina lachiwiri la actinium - anemones nyanja. Pakati pawo pali fyuluta feeders ndi adani. Ndipo mitundu ina ya anemones nyanja akhoza kulowa matanthauzo opindulitsa co-kuli ndi nkhanu kudzipatula.

Polyp amatha muziyendayenda ndi kudya zotsalira za arthropods organic chakudya. A selo khansa kutetezedwa lobaya anemones nyanja. N'zochititsa chidwi kusintha nthawi lakuya, iye kupatsa kumeneko ndi polyp. Cancer zikwapu anemone zikhadabu kusiya yekha amakwawa mu nyumba yatsopano.

A njuchi ndi tizilombo ting'onoting'ono matanthwe kupanga limodzi yaikulu. Mwachitsanzo, Wamkulu Barrier Reef akutambasula m'mphepete mwa nyanja Australia pa mtunda 2 zikwi makilomita.

Kutanthauza coelenterates mu chikhalidwe ndi moyo wa anthu

coelenterates ambiri akhoza kukhala owopsa kwa nyama ndi anthu. Ntchito maselo awo lobaya amachititsa amayaka. zotsatira zawo munthu angakhale omangana, mutu, zipolowe za mtima ndi ziwalo kupuma. Ngati nthawi si kuthandiza, ndi imfa zotheka.

Tizilombo ting'onoting'ono ndi modabwitsa ndi mgwirizano zofunika unyolo kotunga okhala madzi. A matanthwe m'mayiko ambiri amagwiritsa ntchito kupanga zibangili, alendo ndi zomangira.

Choncho, mtundu Coelenterates, khalidwe ambiri kuti ankakambirana ukufanizidwa ndi zamoyo ziwiri. Izo ndi tizilombo ting'onoting'ono ndi modabwitsa. Nyama zimenezi yodziwika ndi zozungulira chosokonekera, pamaso pa maselo apadera, ndipo kusinthana Kwa mibadwo mu mkombero moyo.
