Qhov Tseem Ceeb - Platyhelminthes vs Aschelminthes
Platyhelminthes thiab Aschelminthes yog qhov loj invertebrate phyla ntawm Kingdom Animalia. Platyhelminthes yog acoelomates thaum Aschelminthes yog pseudo-coelomates. Qhov no yog qhov sib txawv tseem ceeb ntawm Platyhelminthes thiab Aschelminthes.
Invertebrates txhais tau tias yog cov tsiaj uas tsis muaj pob txha. Lwm cov phyla loj uas suav nrog invertebrates yog Cnidaria, Annelida, Arthropoda, Mollusca, thiab Echinodermata.
Platyhelminthes yog dab tsi?
Platyhelminthes yog ib lub phylum uas muaj nyias, mos worms noj cov nplooj los yog zoo ib yam li ribbonlike qauv. Yog li ntawd, Platyhelminthes kuj hu ua flatworms. Lawv pom muaj nyob hauv tsev neeg planaria nyob hauv cov pas dej thaum cov kab mob xws li flukes thiab tapeworms muaj nyob rau hauv cov tsiaj lub cev thiab tib neeg.
Qee yam ntxwv tam sim no los txhais qhov xwm ntawm Platyhelminthes. Qhov tsis muaj lub cev kab noj hniav (acoelomate), lub cev muaj peb cov ntaub so ntswg txheej (triploblastic) thiab muaj lub taub hau meej thaum lub cev sib luag rau ob sab laug thiab sab xis (ob tog sib luag) yog cov yam ntxwv ntawm Platyhelminthes.
Daim duab 01: Tus kab mob flatworm Pseudoceros dimidiatus
Lub phylum Platyhelminthes muaj cov chav sib txawv uas suav nrog chav kawm Turbellaria, chav kawm Cestoda, thiab chav kawm Trematoda. Chav Kawm Turbellaria muaj ntau yam kab mob nyob dawb thiab qee qhov yog kab mob parasitic. Trematodes feem ntau hu ua flukes. Lawv yog cov kab mob parasitic flatworms nrog lub cev tsis muaj segmented. Tapeworms yog hu ua Cestodes. Chav Kawm Cestoda muaj cov tswv cuab nrog cov yam ntxwv xws li segmented ribbon zoo li lub cev thiab cov kab mob cab.
Aschelminthes yog dab tsi?
Phylum Aschelminthes txhais tau tias yog ib qho phylum uas tsis siv lawm uas muaj cov cab zoo li cov pob txha. Lawv raug xa mus rau nematodes kuj vim tias cov chav kawm loj uas yog cov phylum no yog chav kawm nematodes. Nrog rau cov nematodes muaj lwm cov chav kawm ntawm invertebrates xws li Rotifera, Gastrotricha, Kinorhyncha, Acanthocephala thiab Nematomorpha.
Raws li kev faib tawm tam sim no, txhua chav kawm tau muab faib ua phylum cais. Qhov laj thawj ntawm kev faib tag nrho cov tsiaj no ua ke ua ib pawg yog vim muaj cov pseudocoelom. Tsis zoo li ib coelom, qhov no yog ib hom kab noj hniav hauv lub cev uas tsis muaj cov kab mob mesoderm tam sim no. Tab sis tom qab ntawd nws tau pom tias cov tsiaj no tsis muaj kev sib txuas ntawm lawv cov evolutionary thiab yog li ntawd, txhua chav kawm ntawm cov tsiaj tau muab faib ua lawv tus kheej phyla.
Daim duab 02: Aschelminthes
Rotifers thiab acanthocephalans muaj kev sib raug zoo ntawm kev hloov pauv thiab yog li ntawd, ob chav kawm no tau muab tso rau hauv tib lub cev. Vim tag nrho cov laj thawj no, Aschelminthes tau tshaj tawm tias yog ib qho phylum uas tsis siv lawm raws li kev faib tawm niaj hnub no.
Qhov Zoo sib xws ntawm Platyhelminthes thiab Aschelminthes yog dab tsi?
- Ob leeg Platyhelminthes thiab Aschelminthes yog invertebrates.
- Ob leeg tsis muaj pob txha.
- ob leeg tsis muaj qhov tseeb.
- Ob Platyhelminthes thiab Aschelminthes yog tsiaj yooj yim.
- Ob hom tsiaj ua txhua yam haujlwm tseem ceeb hauv lub cev.
Qhov txawv ntawm Platyhelminthes thiab Aschelminthes yog dab tsi?

Summary – Platyhelminthes vs Aschelminthes
Cov kab mob tsis muaj kab mob tsis muaj kab mob tsis muaj pob txha. Platyhelminthes thiab Aschelminthes yog invertebrates uas tsis muaj pob txha. Txawm hais tias Platyhelminthes raug suav hais tias yog phylum txog niaj hnub no, Aschelminthes raug suav hais tias yog ib pawg neeg tsis siv neeg. Yog vim li cas rau kev faib tag nrho cov Aschelminthes ua ke ua ib pawg yog vim muaj ib tug pseudocoelom. Tam sim no lawv tau raug muab cais ua cais phyla. Platyhelminthes yog ib tug phylum uas muaj nyias, mos worms noj cov nplooj los yog zoo li ribbonlike qauv. Lub phylum Platyhelminthes muaj cov chav sib txawv uas suav nrog Class Turbellaria, Class Cestoda, thiab Class Trematoda. Phylum Aschelminthes yog txhais tau tias yog ib qho phylum uas tsis siv lawm uas muaj cov kab mob sib kis zoo li invertebrates. Qhov no yog qhov txawv ntawm Aschelminthes thiab Platyhelminthes.
