Chaza inqubo ukudla ukugaya kanye Hydra: izici physiology coelenterates

"Chaza inqubo ukugaya ukudla kanye Hydra" - ukwenza lo msebenzi ngokuqinisekile akubona bonke. Ngemva kwesikole kwezilwane Yiqiniso akuyona kakhulu ezinemininingwane ngokucabangisisa ngodaba. Ndawonye Masihlale sihlale sivuselele olwazini nasekuqondeni esinako sibheke indlela Hydra feeds.

izici isakhi Hydra

Amachibi Hydra kuyinto omele ejwayelekile ye uhlobo Coelenterata. Kuyinto isibonelo isilwane cwaningo ezinamangqamuzana amaningi Lobu bunye ehlelekile. Ibala lesikhumba Hydra sifana Isiqu esincane, okuyinto unamathele base. Angase akhonze emnyango njengoba phansi echibini, amatshe noma ezinye substrate. Ekupheleni mahhala umzimba elise ihambe. Ngamandla abo Hydra kuzingelwa izilwanyana zasemanzini ezifana ciliates, ezinamagobolondo noma ngezinye izikhathi ngisho gazinga inhlanzi.

Lunye kwamaseli

Siyaqhubeka zuku "Chaza inqubo ukugaya ukudla kanye Hydra". Ukuze uqonde lo mbuzo, okokuqala thola ukuthi ulungisele isilwane. Naphezu kweqiniso lokuthi Hydra kuyinto amaningi, indwangu samanje enendawo cha. Kodwa umzimba wakhe Kumiswa akuyona amaseli efanayo, futhi ezikhethekile, uhlobo ngalunye lapho wenza umsebenzi walo. Ngakho, ngosizo isikhumba kanye muscle Hydra uhamba. Kodwa amangqamuzana ezinzwa chithi saka emzimbeni, eyenziwa ubuhlobo imvelo. Kukhona umzimba Hydra futhi gametes - amaqanda nesidoda. Zifeza inqubo ngokobulili ukukhiqizwa kabusha coelenterates.

Yini nokuthi ukudla Hydra

Izilwane ezincane-oluncane kanye yezilwane ezinomgogodla, okuyinto ukuhambisa eduze Hydra angenasawoti, kukhona wo isisulu esilula kakhulu. Animal Ubamba kubo ne tentacles wamthuma inesikhala emathunjini for kokudla esiswini olwengeziwe. Kodwa ngaphambi kokuba lokho isilwane paralyzes inyamazane yayo. Izici Hydra kukhona ebukhoneni amaseli kabuhlungu. Ngamunye wabo siqukethe capsule lapho intambo elisontiwe. Top iseli esintinyelayo izinwele ebucayi. Uma kuziwa isisulu, intambo uphendulela futhi aphendule ngomfutho ukwelula emzimbeni. Nale ekukhiqizeni ushevu ungena emzimbeni, kuba paraliziruyuschy ngokuphelele. iseli esintinyelayo wenza umsebenzi walo kanye kuphela, ngemva kwalokho uyafa. Kodwa emzimbeni we Hydra ngokushesha avele entsha. Lokhu kungenxa nokuhlukana kwamangqamuzana ezemfundo, okuyinto zisenza sibe zonke ezinye izinhlobo.

ingaphakathi emathunjini

Ngakho, ngenxa yomsebenzi ehlelekile ukukhiqizwa tentacles namaseli esintinyelayo ngokuphelele e mafutha anciphisa isikhala esingaphakathi emathunjini we Hydra. Lapha-ke echayeke enzyme amaseli yezindlala. Bakha yelikhono begazi, ngaphansi isenzo lapho ingxenye enkulu ukudla ukugqekeza izinsalela. Kuthiwa isimiso sokugaya ukudla bungene zonke izinhlobo Abamele Coelenterates ivaliwe hlobo. Kuyinto isintu impela e isakhiwo kanye imelelwa kuphela umlomo kanye ingaphakathi emathunjini. Izigaba asele azikho. Lokhu kusho ukuthi ukudla undigested doti ziyasuswa ngomlomo. Yiqiniso, lokhu isimiso sokugaya ukudla bungene ulula futhi bakudala. Nokho, uma sihlola ndaba yokuziphendukela kwemvelo, singabona nezici ezithuthukayo. Uma izilwane lokuqala ezinamangqamuzana amaningi - emihlathini - Amandla inqubo zokuhlunga emelelwa izinhlayiya ezidliwayo kusukela emanzini, Hydra ngokuzimela okuzingela ke ine nezindlala Analogue and lucwaningo ukwelashwa chemical ukudla. Ngakho ukuthi isakhiwo angabhekwa kwetintfo ngeso lenyama. Lapha sibona kancane ayesesha esondela eduze kwaleli impendulo "Chaza inqubo ukugaya ukudla kanye Hydra".

ukugaya yeselula

Kodwa ingaphakathi emathunjini ukugaya inqubo e Hydra, njengazo zonke coelenterates akugcini. Emva nokwahlukana yaba izicucu izinhlayiya zichayeka nezinye izinhlangano ezikhethekile. Lokhu amaseli yesisu zitholakala ungqimba engaphakathi komzimba wonke angenasawoti Hydra. Sinenkosi flagella zabo, ekwazi ukukhiqiza yamanzi. Naye ukudla ifinyelela ebusweni kulezi cells. Ngokulandelayo, ubambe kwengaphansi yonyawo lwalo zamanga. Ngakho ukudla ngaphakathi namangqamuzana akhethekile. Le ndawo Esigabeni sokugcina inqubo ukugaya. It iphela vacuoles wokugaya ukudla usebenzisa enzyme hydrolytic. Iphinde kwakheka izinsalela undigested ziyasuswa ngomlomo.

Ngakho, i-angenasawoti Hydra ukugaya kanyekanye ejwayelekile ka izinhlobo ezimbili: cavernous kanye neselula. Eyokuqala kwenzeka mafutha anciphisa isikhala esingaphakathi emathunjini nge amaseli yezindlala ama-enzyme i-ukugaya ukudla. Eyesibili esigabeni sokugcina. Kuyinto isici amaseli ezikhethekile kanye vacuoles wokugaya ukudla. Ngicabanga ukuthi manje umsebenzi "Chaza inqubo ukugaya ukudla kanye Hydra" ngeke kukwenze ubani izinkinga.
