Qhov sib txawv tseem ceeb ntawm biramous thiab uniramous arthropods yog tias biramous arthropods muaj cov ceg tawv nrog ob ceg, txhua qhov muaj cov ntu txuas mus rau qhov kawg, thaum cov uniramous arthropods muaj cov ceg tawv nrog ib ntu ntawm ntu txuas nrog kawg-rau- kawg.
Phylum Arthropoda belongs rau Kingdom Animalia. Nws yog cov phylum uas muaj ntau hom tsiaj thiab cov neeg coob tshaj plaws, suav nrog cov kab. Arthropods muaj ib qho exoskeleton, segmented lub cev thiab ua khub koom nrog appendages. Arthropod's appendages, tshwj xeeb tshaj yog cov ceg tawv, tuaj yeem yog biramous lossis uniramous. Muaj ib tug series ntawm ntu txuas mus rau qhov kawg ntawm lub uniramous limb. Nyob rau hauv sib piv, nyob rau hauv biramous libs, muaj ob ceg, txhua tus muaj ib tug series ntawm ntu txuas mus rau qhov kawg. Kab thiab myriapods muaj uniramous ob txhais ceg thaum crustaceans muaj biramous ob txhais ceg.
Dab tsi yog Biramous Arthropods?
Biramous libs yog arthropod libs / ceg uas muaj ob ceg. Nyob rau hauv txhua ceg, ib tug series ntawm ntu yog txuas mus rau qhov kawg. Crustacean libs yog biramous. Yog li ntawd, lawv muaj ob ceg ntawm lawv ob txhais ceg. Lawv raug hu ua exopod thiab endopod.
Daim duab 01: Biramous thiab Uniramous Limbs
Exopod yog ceg sab nraud lossis ramus. Endopod yog lub sab hauv. Tsis tas li ntawd, lawv lub kav hlau txais xov thib ob kuj yog biramous. Endopod feem ntau yog siv rau kev taug kev lossis hloov kho rau kev tuav, zom, lossis rov ua dua. Ntawm qhov tod tes, tus exopod feem ntau yog ib qho flattened gill.
Dab tsi yog Uniramous Arthropods?
Nqaij npua teb tsis muaj ceg. Lawv muaj ib tug series ntawm ntu txuas mus rau qhov kawg tsis muaj branching. Ob txhais ceg ntawm kab, myriapods thiab hexapods yog uniramous. Yog li ntawd, lawv ob txhais ceg tsis branched ua ob, zoo li nyob rau hauv biramous. Qhov xwm ntawm uniramous libs yog ib tug sib koom yam ntxwv. Li no, nws yog siv los pab pawg uniramous arthropods rau hauv ib lub taxon hu ua uniramia.

Ntxiv mus, nws ntseeg tau tias ntau pab pawg ntawm arthropods hloov zuj zus ntawm cov ceg tsis muaj zog los ntawm cov poj koob yawm txwv nrog cov ceg tawv biramous los ntawm kev poob ntawm exopods.
Dab tsi yog qhov zoo sib xws ntawm Biramous thiab Uniramous Arthropods?
- Biramous thiab uniramous yog ob hom arthropod sib koom ceg ceg raws li ceg lossis qhov tsis muaj nws.
- Ob hom appendages muaj cov ntu txuas txuas mus rau qhov kawg.
- Cov caj npab no muaj txiaj ntsig zoo rau arthropods rau kev taug kev thiab lwm yam.
Qhov txawv ntawm Biramous thiab Uniramous Arthropods yog dab tsi?
Biramous arthropods yog cov tswv cuab ntawm arthropods uas muaj ob ceg ceg. Ntawm qhov tod tes, uniramous arthropods yog cov tswv cuab ntawm arthropods uas tsis muaj ceg tawv. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm biramous thiab uniramous arthropods. Biramous libs muaj ob ceg thaum uniramous libs yog unbranched. Piv txwv li, crustaceans muaj cov ceg tawv, thaum kab, myriapods thiab hexapods muaj cov ceg tsis zoo. Tsis tas li ntawd, ob ceg ntawm biramous ceg yog hu ua exopods thiab endopods thaum uniramous ceg tsis muaj ob hom.
Hauv qab infographic qhia txog qhov sib txawv ntawm biramous thiab uniramous arthropods.
Summary – Biramous vs Uniramous Arthropods
Arthropods muaj appendages uas tau sib koom ua ke. Lawv tuaj yeem yog biramous lossis uniramous. Biramous appendages yog branched nyob rau hauv ob. Txhua ceg muaj ib tug series ntawm ntu txuas mus rau qhov kawg. Nyob rau hauv sib piv, uniramous appendages tsis branched. Nws muaj ib tug series ntawm ntu txuas mus rau qhov kawg. Feem ntau, crustacean libs yog biramous thaum kab, myriapods thiab hexapods libs yog uniramous. Yog li, qhov no qhia txog qhov sib txawv ntawm biramous thiab uniramous.
