Qhov sib txawv tseem ceeb ntawm arthropods thiab annelids yog tias cov arthropods yog ib pawg ntawm cov pob txha tsis muaj zog uas suav nrog cov tsiaj muaj lub cev segmented, ib qho exoskeleton thiab khub appendages thaum annelids yog lwm pab pawg invertebrates uas suav nrog segmented worms muaj cov nplhaib hla.
Arthropoda thiab Annelida yog ob qhov sib txawv thiab tseem ceeb ntawm lub Nceeg Vaj Animalia. Ob lub phyla no txawv ntawm ib leeg los ntawm ntau tus yam ntxwv xws li kev sib txawv ntawm kev sau se, lub koom haum lub cev, ecological specializations, thiab lwm yam. Yeej, phylum Arthropoda muaj invertebrates uas muaj ib tug exoskeleton, ib tug segmented lub cev, thiab paired jointed appendages thaum phylum annelids muaj segmented worms xws li leeches., earthworms, thiab lwm yam. Kab lus no muab cov ntaub ntawv yooj yim thiab cov ntsiab lus piav qhia txog qhov sib txawv ntawm arthropods thiab annelids thiab thaum kawg nthuav tawm ib sab ntawm kev sib piv rau kev pom zoo dua.
Arthropods yog dab tsi?
Arthropods yog ib pawg ntawm cov pob txha tsis muaj zog uas muaj lub cev pob txha sab nraud, lub cev ntu, thiab ua ke nrog cov khoom siv. Lawv yog pab pawg tsiaj sib txawv tshaj plaws nyob rau hauv tag nrho lub nceeg vaj nrog ntau dua 1.17 lab tus tsiaj uas tau piav qhia. Tsis tas li ntawd, ntau tshaj 80% ntawm cov hom piav qhia yog arthropods. Lawv feem ntau suav nrog ntau hom kab, crustaceans, arachnids, thiab lwm cov tswv cuab arthropod. Lawv lub cev segmented, sib koom ua ke, thiab chitinous exoskeleton yog cov yam ntxwv tseem ceeb uas sib txawv ntawm lwm yam tsiaj.
Lub cev arthropod muaj peb ntu lossis tagma: taub hau, thorax, thiab plab. Tsis tas li ntawd, lawv muaj segmented ob txhais ceg, thiab lawv cov exoskeleton hloov tau ntawm cov junctions. Lub exoskeleton (cuticle) yog ib qho tawv npog uas muaj chitin. Yog li, nws muab kev tiv thaiv zoo rau tsiaj.
Daim duab 01: Arthropods
Tsis tas li ntawd, arthropods muaj qhov qhib circulatory system uas cov ntshav ncig hauv lub cev los ntawm kev sau cov haemocoels. Arthropods muaj ob lub qhov muag, thiab lawv pom qhov muag pom los ntawm cov qhov muag sib xyaw. Lawv feem ntau muaj kav hlau txais xov rau lwm txoj kev ntsuas. Ob qho tib si sab hauv thiab sab nraud fertilization txheej txheem yog tam sim no ntawm arthropods. Txawm li cas los xij, txhua tus poj niam laus nteg qe tom qab kev sib raug zoo nrog tus txiv neej. Cov theem larval dhau los ua neeg laus tom qab lub sijhawm sib txawv tom qab kev loj hlob, thiab lub sijhawm ntawd sib txawv ntawm txhua hom. Raws li cov tsiaj no loj hlob, lawv tso lawv cov exoskeleton ntau zaus thaum lawv lub neej. Zuag qhia tag nrho, kev txaus siab txog cov tsiaj no yuav tsis muaj qhov kawg vim tias muaj cov tswv cuab ntawm cov duab me me mus rau ob peb meters ntev, thiab lawv tuaj yeem txhawb nqa txawm tias nrog ib tus tsiaj ntawm txhua qhov chaw thiab tuaj yeem loj hlob mus txog ntau lab nrog lub sijhawm.
Annelids yog dab tsi?
Annelids yog ib lub cev loj uas muaj cov kab mob segmented xws li ragworms, earthworms, thiab nuisance leeches. Tam sim no, muaj ntau tshaj li 17,000 hom tsiaj ntawm annelids. Feem ntau, lawv nyob hauv cov dej tshiab los yog dej ntsev thiab nyob ib puag ncig thaj chaw ntub dej. Annelid muaj lub cev elongated thiab segmented los ntawm transverse nplhaib zoo li constrictions. Cov kev txwv no yog hu ua annuli, thiab lawv nyob hauv segmented lossis partitioned ntawm septa ntawm tib qhov chaw raws li lub annuli.
Daim duab 02: Annelid
Annelids zais lawv cov cuticle los ntawm lawv cov tawv nqaij. Collagen yog cov protein uas ua rau lub cuticle annelid, thiab nws tsis nyuaj heev. Ntau tus kws tshawb fawb ntseeg tias lawv muaj capillaries coj ntshav los ntawm lub cev. Txawm li cas los xij, annelids muaj lub kaw lus kaw. Lawv feem ntau tsis moult lawv cov cuticle, tab sis qee hom ua rau lawv cov tawv nqaij (leeches) lossis puab tsaig (polychaetes). Lawv lub cev kab noj hniav yog coelom, tab sis qee hom annelid tsis muaj coelom, thiab qee qhov muaj nyob rau hauv qhov chaw me me.
Dab tsi yog qhov zoo sib xws ntawm Arthropods thiab Annelids?
- Arthropods thiab Annelids yog ob lub phyla loj ntawm Kingdom Animalia.
- Ob lub phyla yog tsim los ntawm cov kab mob uas muaj segmented lub cev.
- Tsis tas li, ob qho tib si phyla muaj cov pob txha tsis muaj zog.
- Ntxiv mus, ob qho tib si tsis muaj cov kab mob endoskeletons.
Qhov txawv ntawm Arthropods thiab Annelids yog dab tsi?
Ob leeg arthropods thiab annelids yog ob pawg ntawm invertebrates uas zwm rau lub nceeg vaj Animalia. Lawv tsis muaj qhov endoskeleton. Txawm li cas los xij, phylum arthropoda muaj cov tsiaj uas muaj lub cev segmented, ib qho exoskeleton, thiab khub appendages. Whereas, phylum annelid muaj segmented worms uas muaj transverse rings. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm arthropods thiab annelids. Qhov tseem ceeb, qhov sib txawv tseem ceeb ntawm arthropods thiab annelids yog tias arthropods muaj chitinous exoskeleton thaum annelids tsis muaj exoskeleton.
Ntxiv mus, arthropods muaj chitinous cuticle thaum annelids muaj collagenous cuticle. Tsis tas li ntawd, annelids yog worms thiab tsis muaj ob txhais ceg, tab sis lawv muaj parapodia rau locomotion, thaum arthropods muaj segmented appendages rau locomotion. Yog li, qhov no kuj yog qhov sib txawv tseem ceeb ntawm arthropods thiab annelids. Tsis tas li ntawd, lwm qhov sib txawv ntawm arthropods thiab annelids yog tias annelids feem ntau muaj lub kaw lus kaw thaum nws yog qhov qhib hauv arthropods. Ntxiv mus, ntau haiv neeg yog siab heev ntawm arthropods piv rau annelids.
Cov hauv qab no qhia txog qhov sib txawv ntawm arthropods thiab annelids hauv daim ntawv teev npe.
Summary – Arthropods vs Annelids
Arthropods yog cov tsiaj tsis muaj txhav uas muaj lub cev segmented, exoskeleton, thiab khub appendages. Whereas, annelids yog lwm pab pawg ntawm invertebrates uas yog segmented worms los ntawm transverse rings. Txawm hais tias arthropods muaj ib qho exoskeleton, annelids tsis ua. Tsis tas li ntawd, arthropods muaj qhov qhib circulatory system thaum annelids muaj lub kaw lus kaw. Ntxiv mus, arthropods muaj chitinous cuticle thaum annelids muaj collagenous cuticle. Kab, crustaceans, arachnids yog ob peb pawg ntawm arthropods thaum earthworms, ragworms, thiab leeches yog qee pawg ntawm annelids. Yog li, qhov no qhia txog qhov sib txawv ntawm arthropods thiab annelids.
