Hepatophyta txhais tau tias "liab nroj tsuag" thiab hais txog lub cev ntawm qee hom kab mob siab, uas nws cov lobing tseem ceeb ntawm lub siab. Thallose liverworts muaj gametophytes nrog lub cev tsis sib xws hu ua thallus uas muaj ribbon-zoo li tshwm sim.
Tom qab ntawd, phylum Hepatophyta yog dab tsi?
Cov nroj tsuag tsis muaj vascular suav nrog cov mosses niaj hnub ( phylum ua Bryophyta), kab mob siab ( Cov kab mob Hepatophyta ), thiab hornwort ( Anthocerophyta ntawm phylum ). Ua ntej, lawv qhov tsis muaj cov ntaub so ntswg txwv lawv lub peev xwm thauj dej sab hauv, txwv qhov loj me uas lawv tuaj yeem ncav cuag ua ntej lawv qhov chaw sab nraud.
Ib yam li ntawd, dab tsi faib liverworts koom nrog? Kev lig kev cai, lub kab mob siab tau koom ua ke nrog lwm cov bryophytes (mosses thiab hornworts) hauv Kev faib Bryophyta, nyob rau hauv uas lub kab mob siab tsim cov chav kawm Hepaticae (tseem hu ua Marchantiopsida).
Ntawm no, yog Gemmae khob haploid lossis diploid?
Nyob rau hauv liverworts xws li Marchantia, lub flattened plantbody los yog thallus yog ib tug haploid gametophyte nrog gemmacups tawg tawm ntawm nws saum npoo av. Cov gemma khob yog khob -zoo li cov qauv uas muaj yam . Cov yam yog me me discs haploid cov ntaub so ntswg, thiab lawv ncaj qha ua rau cov gametophytes tshiab.
Cov tiam twg yog lub liverwort thallus?
Qhov gametophyte tiam muaj cov thehaploid lus thiab yog tus tseem ceeb tiam ; Nws tsim los ntawm germinating spore.

Koj txhais qhov hnyav txhais li cas?
Cov ntsiab lus. Weighted Mean: Ib qho txhais tau tias qee qhov txiaj ntsig pab ntau dua li lwm tus. Thaum qhov hnyav ntxiv rau 1: tsuas yog muab txhua qhov hnyav los ntawm tus nqi sib xws thiab suav tag nrho. Txwv tsis pub, muab txhua qhov hnyav w los ntawm nws qhov sib piv tus nqi x, suav tias tag nrho, thiab faib los ntawm qhov sib npaug ntawm qhov hnyav: Qhov Ntsuas Ntsuas = ΣwxΣw
Cov ntsiab lus hydrophilic thiab hydrophobic txhais li cas thiab lawv cuam tshuam li cas?
Hydrophobic txhais tau hais tias cov molecule yog "ntshai" dej. Cov tails ntawm phospholipid yog hydrophobic, txhais tau tias lawv nyob hauv daim nyias nyias. Hydrophilic txhais tau hais tias cov molecule muaj affinity rau dej
Vim li cas nws tseem ceeb kom paub tias koj txhais li cas ntxiv?
Txhais qhov seem. Kev txhais cov lus tseem ceeb yog qhov tseem ceeb thaum koj faib ua lej vim tias koj tuaj yeem tau txais qhov teeb meem tsis raug yog tias koj tsis txhais cov seem kom raug. Piv txwv li, nyob rau hauv ib lo lus teeb meem koj yuav tsum tau faib thiab faib tawm rau koj nrog ib tug seem thiab koj yuav tsum tau muab sau tseg
Koj txhais li cas los ntawm lo lus txhais?
Lub ntsiab lus txhais yog ib nqe lus ntawm lub ntsiab lus ntawm ib lo lus (ib lo lus, kab lus, lossis lwm yam cim). Cov lus txhais tau muab faib ua ob pawg loj, cov ntsiab lus tsis txaus ntseeg (uas sim muab lub ntsiab lus ntawm lub ntsiab lus) thiab cov ntsiab lus txuas ntxiv (uas sim sau cov khoom uas ib lo lus piav qhia)
Txhais tau li cas los txhais ib daim duab peb sab?
Kev txhais lus. Kev txhais lus yog ib qho kev hloov pauv uas tshwm sim thaum ib daim duab tau txav los ntawm ib qho chaw mus rau lwm qhov chaw yam tsis tau hloov nws qhov loj, duab lossis kev taw qhia. Txhawm rau txhais cov ntsiab lus P (x, y), ib chav nyob sab xis thiab b units, siv P'(x + a, y + b)
