Raws li qhov system no, tsob ntoo ntawm lub neej muaj peb domains : Archaea, Kab mob, thiab Eukarya. Thawj ob yog tag nrho cov kab mob prokaryotic, los yog ib leeg-celled kab mob uas lawv cov hlwb tsis muaj nucleus.

Tsuas yog li ntawd, 3 hom kev sau npe yog dab tsi?

Peb lub npe yog Archaea, Cov Kab Mob, thiab Eukarya. 4. Cov kab mob Prokaryotic yog ib yam ntawm cov sau Archaea los yog domain Bacteria; Cov kab mob uas muaj eukaryotic hlwb muaj nyob rau sau npe Eukarya.

Tsis tas li ntawd, peb lub Nceeg Vaj hauv biology yog dab tsi? Peb Domains of Life Lub tswv yim feem ntau siv tam sim no faib tag nrho cov kab mob nyob rau hauv tsib lub nceeg vaj : Monera (bacteria), Protista, Fungi, Plantae, thiab Animalia. Qhov no coexisted nrog lub tswv yim faib lub neej rau hauv ob lub ntsiab faib: Prokaryotae (cov kab mob, thiab lwm yam).

Hauv qhov no, dab tsi yog qhov tseem ceeb hauv biology?

Hauv lom taxonomy, ib sau npe (tseem superregnum, superkingdom, los yog faj tim teb chaws) yog ib tug taxon nyob rau hauv lub siab tshaj plaws qeb ntawm cov kab mob, siab tshaj lub nceeg vaj. Peb- sau npe system ntawm Carl Woese, qhia hauv xyoo 1990, nrog cov pab pawg sab saum toj ntawm Archaea, Bacteria, thiab Eukaryota thaj chaw.

Peb lub neej yog dab tsi thiab lawv txawv li cas?

Txhua lub neej tuaj yeem muab faib ua peb yam, raws li hom cell ntawm lub cev: Kab mob : cov hlwb tsis muaj cov nucleus. Archaea : hlwb tsis muaj nucleus; lawv muaj phab ntsa sib txawv ntawm tes kab mob . Eukarya : Cell muaj ib tug nucleus.
