Qhov Tseem Ceeb - Coelenterates vs Platyhelminthes
Kingdom Animalia muab faib ua ob pawg tseem ceeb xws li vertebrates thiab invertebrates. Invertebrates tau muab faib ntxiv rau hauv phyla tawm ntawm ob qhov tseem ceeb tshaj plaws phyla yog Phylum Coelenterate thiab Phylum Platyhelminthes. Phylum Coelenterata, tseem hu ua Cnidaria, yog hom kab mob qub qub tshaj plaws thiab yog cov tsiaj txhu diploblastic uas tsuas muaj ectoderm thiab endoderm. Phylum Platyhelminthes feem ntau yog cov kab mob parasitic, thiab lawv yog cov tsiaj txhu triploblastic uas cov ectoderm tshwj xeeb nrog cov epidermis tseem ceeb. Qhov sib txawv tseem ceeb ntawm Coelenterata thiab Platyhelminthes yog nyob ntawm cov kab mob ntawm cov kab mob. Coelenterates yog diploblastic invertebrates whereas Platyhelminthes yog triploblastic invertebrates.
Coelenterates yog dab tsi?
Coelenterates yog triploblastic coelomates uas feem ntau pom nyob rau hauv dej, feem ntau yog ib puag ncig marine. Lawv muaj nyob rau hauv kev sib cais los yog raws li cov colonies. Lawv qhia cov qauv kev noj haus holozoic thiab ob qho tib si extracellular thiab intracellular digestion tshwm sim. Lawv muaj lub cev tshwj xeeb hu ua nematocyst, uas yog siv los tiv thaiv nws tus kheej los ntawm cov tsiaj nyeg. Lawv muaj lub paj hlwb tsis tiav, thiab cov hlab ntsha tsis tiav. Coelenterates muaj nyob rau hauv ob hom loj. Ob daim ntawv tseem ceeb yog medusa thiab polyp. Lawv yug me nyuam ob leeg deev thiab asexually. Asexual reproduction tshwm sim los ntawm budding. Lawv tuaj yeem fertilize ob sab hauv thiab sab nraud.
Daim duab 01: Hydra
Coelenterates tau muab faib ua peb chav kawm tseem ceeb xws li; Class Hydrozoa, Class Scyphozoa, thiab Class Anthozoa. Class Hydrozoa yog cov ntaub ntawv marine ntawm Coelenterata. Lawv feem ntau nyob rau hauv daim ntawv polyp, thiab cov piv txwv muaj xws li Hydra, Obelix, thiab Tubularia. Class Scyphozoa yog marine dawb-nyob daim ntawv ntawm coelenterates. Medusa daim ntawv yog daim ntawv tseem ceeb uas cov scyphozoans muaj lub kaus zoo li tus qauv. Cov piv txwv muaj xws li Aurelia (Jellyfish). Class Anthozoa marine kab mob uas muaj nyob rau hauv ib leeg los yog colony cov ntaub ntawv. Cov piv txwv muaj xws li Metridium (Hiav txwv anemone).
Platyhelminthes yog dab tsi?
Platyhelminthes kuj tseem hu ua flatworms thiab koom nrog pab pawg ntawm invertebrates. Platyhelminthes feem ntau yog parasitic, thiab lawv yog triploblastic acoelomates. Lawv qhia ob sab symmetry, thiab lub cev yog dorso-ventrally flattened. Cov kab mob hauv qab phylum Platyhelminthes tsis muaj cov kwj dej ua tiav tab sis muaj cov qauv pharynx tseem ceeb uas pab hauv kev zom zaub mov. Ib qho kev tsim circulatory system tsis tuaj lawm tab sis muaj lub cev tshwj xeeb rau excretion hu ua protonephridia nrog cov nplaim hluav taws. Lawv ua pa los ntawm qhov yooj yim diffusion ntawm gases thoob plaws lub cev. Kev yug me nyuam hauv flatworms tuaj yeem yog nyob rau hauv cov ntaub ntawv kev sib deev ntawm gamete tsim los yog los ntawm kev sib deev. Asexual txoj kev ntawm Platyhelminthes suav nrog kev rov tsim dua tshiab thiab fission.
Daim duab 02: Platyhelminthes
Phylum Platyhelminthes tau muab faib ua peb pawg loj - Turbellaria, Trematoda, Cestoda. Class Turbellaria yog cov kab mob tsawg dua ntawm Platyhelminthes. Lawv pom nyob rau hauv ib puag ncig dej tshiab thiab feem ntau tsis muaj hooks lossis suckers, tsis zoo li ob chav kawm. Cov piv txwv muaj xws li Planaria, Bipalium. Chav Kawm Trematoda, muaj cov kab mob tsis tshua muaj kab mob ntawm Platyhelminthes. Lawv yog cov kab mob intracellular thiab muaj cov hooks tseem ceeb. Cov no ua rau lub cev ua kom nws tus kheej ua tus kab mob intracellular. Piv txwv ntawm chav kawm Trematoda yog Fasciola hepatica (Liver fluke) thiab Diplozoon. Chav Kawm Cestoda kuj yog chav kawm ntawm cov kab mob Platyhelminthes. Lawv kuj muaj hooks thiab suckers. Cov piv txwv ntawm cov kab mob uas nyob rau hauv chav kawm Cestoda yog Taenia spp. (tapeworm) thiab Convoluta.
Dab tsi zoo sib xws ntawm Coelenterates thiab Platyhelminthes?
- Ob leeg koom nrog lub nceeg vaj Animalia thiab qeb invertebrate.
- Ob leeg yog cov kab mob hauv dej.
- Ob leeg tsis muaj lub plab zom mov tag.
- Ob leeg raug kev sib deev thiab kev sib deev.
- Ob leeg tuaj yeem ua tus kab mob.

Summary – Coelenterates vs Platyhelminthes
Kingdom Animalia yog ib lub tebchaws loj tshaj plaws thiab rau qhov yooj yim ntawm tus cwj pwm, cov kws sau paj lug faib cov pab pawg loj rau ntau yam phyla. Coelenterates thiab Platyhelminthes yog ob qho tib si invertebrates uas nyob hauv ib puag ncig dej. Coelenterates yog diploblastic coelomates thaum Platyhelminthes yog triploblastic acoelomates. Lawv muaj ob peb lub cev tshwj xeeb rau ntau yam haujlwm thiab muab faib ua cov chav kawm nyob ntawm lawv qhov sib xws. Qhov no yog qhov txawv ntawm Coelentrates thiab Platyhelminthes.
