General maonekedwe a coelenterates

Ngakhale kuti ali multicellular, coelenterates palibe zimakhala. Choncho, palibe iwo ndi ziwalo. Coelenterates amadziwika ndi kukhalapo kwa maselo apadera kuti apange awiri wosanjikiza thupi. The kunja amatchedwa ectoderm. Iwo wapangidwa ndi maselo wapakatikati, obaya, khungu, minofu, kugonana ndi mitsempha.

Endoderm - lamkati wosanjikiza coelenterates thupi. Izi ndi mbali ya thupi mmene coelenterates kugaya chakudya. Taonani zinthu zokhudza thupi la ndondomeko imeneyi ndi chitsanzo cha madzi oyera hydra.

Hydra si amatha kuyenda yogwira. Ntchito ngati sucker iwo amagwira yekha, pa mbali ina ya umene uli pakamwa. Wazunguliridwa ndi tentacles. Kodi coelenterates kugaya chakudya? Zimenezi kumayambira M'mimbamo thupi.

Hydra amakhudza nkhanu yaing'ono ndi nsomba mphutsi ntchito maselo lobaya. Komanso feelers m'zigawo akamayendetsa pakamwa kuti patsekeke thupi. maselo Glandular ali mbali ya endodermal ya kutali wapadera chinsinsi, imene yopuma chakudya munthu zidutswa.

Kapangidwe zotsatirazi, kumene chakudya m'mimba coelenterates ali m'mimba maselo. Ali michirayo imakhala yosiyanasiyana, amene analenga panopa madzi. Ndi chakudya particles zikufika pamwamba selo. Padzakhala siteji yotsatira pogawanikana pamawere ake.

maselo m'mimba komanso mwendo onyenga. Izi anasintha outgrowths cytoplasm. Iwo amatenga chakudya, ndipo mkati mwa selo. Pamenepo, vacuoles m'mimba kumachitika komaliza pogawanikana pamawere ndondomeko. zatsalira Undigested komanso amadziŵika kudzera pakamwa.

Choncho, tidadzatulukira kumene coelenterates kugaya chakudya. ndondomeko izi zikuchitika mu magawo awiri. coelenterates onse adani. Ndi iwo kutilepheretsa nyama maselo lobaya. Tentacles yozungulira pakamwa, kusuntha mu lumen wa matumbo. Pali akuyamba siteji koyamba wa chimbudzi, omwe akufika pa chimake mu maselo apadera endoderm.
