Qhov sib txawv tseem ceeb ntawm mollusks thiab arthropods yog tias mollusks yog mos-bodied invertebrates nrog ib los yog ob lub plhaub thaum arthropods yog tsiaj nrog segmented lub cev, khub appendages thiab exoskeleton.
Phylum Mollusca thiab Phylum Arthropoda yog ob lub vertebrate vertebrate loj uas suav nrog ntau hom tsiaj ntau tshaj li cov phyla hauv Tsiaj Kingdom. Vim qhov kev sib txawv loj no, tib neeg pom qhov nyuaj los faib lawv raws li qhov tseeb phyla. Yog li, tsab xov xwm no tshuaj xyuas lub cev ntawm txhua tus thiab txheeb xyuas cov yam ntxwv ntawm cov qauv, los pab txheeb xyuas qhov sib txawv ntawm mollusks thiab arthropods.
Mollusks yog dab tsi?
Phylum Mollusca yog ib qho ntawm cov phyla loj tshaj plaws hauv Kingdom Animalia. Nws yog thib ob nkaus xwb rau Phylum Arthropoda. Phylum Mollusca muaj ntau dua 110,000 hom tsiaj uas tau txheeb xyuas, thiab lawv nyob hauv ob qho tib si hauv av thiab dej hauv ntiaj teb. Mollusks yog mos-bodied invertebrates nrog ib los yog ob lub plhaub. Ntxiv mus, lawv qhia ob tog symmetry. Feem ntau cov piv txwv rau mollusks muaj xws li qwj, clams thiab squids. Feem ntau, tag nrho cov mollusks muaj ib txheej nyias txheej hu ua mantle, uas nyob ib ncig ntawm lub cev nqaij daim tawv nyob rau hauv lub visceral loj. Mantle secretes lub plhaub tiv thaiv ntawm lub cev. Tsis tas li ntawd, kev sib pauv roj tshwm sim hauv gills.
Daim duab 01: Mollusks
Mollusks muaj qhov qhib circulatory system uas lub plawv tso ntshav mus rau qhov chaw qhib nyob ib ncig ntawm lub cev. Tsis tas li ntawd, lawv muaj lub taub hau tseem ceeb nrog lub qhov ncauj thiab lub cev muaj zog. Mollusks zoo li snails muaj cov leeg pob txha zoo tsim rau kev txav thiab adhesion. Squids muaj tentacles los ntes cov tsiaj txhu thiab txav mus los. Peb chav kawm loj ntawm Phylum Mollusca suav nrog Gastropoda (snails thiab conchs), Bivalvia (clams, oysters, thiab scallops), thiab Cephalopoda (squids, octopuses, cuttlefish, thiab chambered).
Arthropods yog dab tsi?
Phylum Arthropoda yog pawg tsiaj loj tshaj plaws uas muaj ntau tshaj li ib lab hom sib txawv. Lo lus arthropoda muaj lub ntsiab lus ntawm "ko taw ko taw". Sib nrug los ntawm ob txhais ceg, arthropods muaj kev sib koom ua ke xws li antennae, claws, thiab pincers. Cov appendages no pab cov arthropods ua cov dej num sib txawv, suav nrog kev pub noj, ntes cov tsiaj nyeg, mating, thiab kev hnov mob nyob ntawm qhov chaw lawv nyob.
Daim duab 02: Arthropods
Arthropods nthuav tawm ob sab symmetry, ib ntu ntawm lub cev, lub cev kab noj hniav, lub paj hlwb, lub plab zom mov thiab lub cev. Chitin yog lub ntsiab lus tseem ceeb ntawm cov tawv exoskeleton. Lub exoskeleton muab kev tiv thaiv, kev txhawb nqa, thiab npog rau lub cev hauv nruab nrog cev thiab tseem muab cov leeg nqaij sib txuas. Txij li thaum exoskeleton txwv lawv txoj kev loj hlob, arthropods molt lawv cov exoskeleton tsis tu ncua. Phylum Arthropoda muaj plaub pawg: Chelicerata (kab laug sab, mites, thiab scorpions), Crustacea (cws, crabs, lobsters, thiab dej fleas), Hexapoda (kab, springtails thiab cov txheeb ze) thiab Myriapoda (millipedes thiab centipedes).
Dab tsi zoo sib xws ntawm Mollusks thiab Arthropods?
- Mollusks thiab arthropods yog ob lub phyla ntawm Kingdom Animalia.
- Ob pab pawg muaj cov neeg tsis muaj zog.
- Kuj, ob leeg qhia ob tog sib luag.
- Tsis tas li ntawd, ob pab pawg qhia muaj ntau haiv neeg.
Qhov txawv ntawm Mollusks thiab Arthropods yog dab tsi?
Mollusks yog cov nqaij mos-bodied invertebrates nrog ib los yog ob lub plhaub, whereas arthropods yog cov invertebrates nrog segmented lub cev, sib koom ob txhais ceg thiab appendages. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm mollusks thiab arthropods. Phylum Arthropoda yog qhov loj tshaj plaws phylum ntawm Tsiaj Kingdom, thaum Phylum Mollusca yog qhov thib ob loj tshaj plaws. Mollusks muaj xws li qwj, clams thiab squids thaum arthropods muaj kab laug sab, mites, scorpions, cws, crabs, lobsters, kab, thiab lwm yam.
Ntxiv mus, lawv cov qauv anatomical rau qhov chaw ib yam ntxiv rau qhov sib txawv ntawm mollusks thiab arthropods. Qhov ntawd yog; Tsis zoo li arthropods, qee hom mollusk muaj cov leeg taw rau locomotion. Piv txwv li, arthropods zoo li kab muaj tis ya. Tsis tas li ntawd, mollusks muaj mantles uas secrete calcareous txheej los yog puab plhaub thaum arthropods muaj ib tug exoskeleton ua li chitin. Yog li, qhov no kuj yog qhov txawv ntawm mollusks thiab arthropods.
Summary – Mollusks vs Arthropods
Phylum Molluska thiab Phylum Arthropoda yog ob lub phyla loj ntawm Kingdom Animalia. Mollusks yog cov tsiaj mos mos nrog lub plhaub thaum arthropods yog cov tsiaj nrog segmented lub cev. Lawv kuj tau sib koom ua ke appendages thiab ib qho exoskeleton. Ob pawg muaj xws li invertebrates uas qhia ob tog symmetry. Yog li, qhov no qhia txog qhov sib txawv ntawm mollusks thiab arthropods.
