Yam ntxwv. Bryophytes yog cov nroj tsuag vim lawv yog cov photosynthetic nrog chlorophylls a thiab b, khw starch, yog multicellular, tsim los ntawm embryos, muaj sporic meiosis-ib qho kev hloov ntawm tiam neeg-thiab cellulose cell phab ntsa.
Yog li ntawd, Moss puas muaj phab ntsa ntawm tes?
Moss cell phab ntsa : qauv thiab biosynthesis. Cov cell phab ntsa ntawm mosses thiab cov nroj tsuag vascular yog tsim los ntawm tib chav kawm ntawm polysaccharides, tab sis nrog qhov sib txawv ntawm cov saw hlau sab hauv thiab cov qauv.
Tsis tas li ntawd, bryophytes puas muaj nplooj? Mosses thiab liverwort yog lumped ua ke li bryophytes , cov nroj tsuag tsis muaj tseeb vascular cov ntaub so ntswg, thiab sib koom ib tug xov tooj ntawm lwm yam primitive zoo. Lawv kuj tsis muaj tseeb stems, cag, los yog nplooj , txawm lawv muaj cov hlwb uas ua cov haujlwm no. Cov sporophytes ntawm bryophytes ua tsis yog muaj lub neej dawb huv.
Yog li ntawd, bryophytes puas muaj cuticles?
Bryophytes - Thawj thaj av nroj tsuag tom qab algae uas nyob ntawm ntug pas dej thiab cov kwj deg tuaj yeem muaj ua bryophytes . Bryophytes muaj stoma thiab waxy daim tawv nqaij ntawm lawv lub cev uas pab tiv thaiv lawv ntawm dessication.
Dab tsi yog cov yam ntxwv tseem ceeb ntawm bryophytes?
Bryophytes yog ib qho kev faib tsis raws cai uas muaj 3 pawg ntawm cov nroj tsuag uas tsis yog hlab ntsha, uas yog mosses, liverworts, thiab hornworts. Tseem ceeb Cov yam ntxwv ntawm bryophytes yog qhov tsis muaj tseeb hauv paus stems thiab nplooj. Tsis tas li ntawd, rhizoids ua haujlwm ntawm cov hauv paus hniav, qhov tseem ceeb ntawm cov nroj tsuag mus rau saum npoo.

Puas yog eubacteria muaj cov phab ntsa ntawm tes?
Zoo li archeans, eubacteria yog prokaryotes, txhais tau tias lawv cov hlwb tsis muaj nuclei uas lawv DNA khaws cia. Eubacteria raug kaw los ntawm phab ntsa ntawm tes. Phab ntsa yog ua los ntawm cov kab txuas txuas ntawm peptidoglycan, ib qho polymer uas sib txuas ob qho tib si amino acid thiab qab zib chains
Puas yog Spheroplast puas muaj cov phab ntsa ntawm tes?
Ob leeg protoplasts thiab spheroplast xa mus rau cov ntaub ntawv hloov pauv ntawm cov nroj tsuag, kab mob lossis cov kab mob fungal los ntawm cov phab ntsa ntawm tes tau raug tshem tawm ib nrab lossis tag nrho. Cov hlwb no feem ntau muaj tag nrho lwm cov cellular Cheebtsam, tshwj tsis yog cov phab ntsa ntawm tes
Puas yog archaea muaj peptidoglycan hauv lawv cov phab ntsa ntawm tes?
Cov kab mob thiab Archaea sib txawv nyob rau hauv lipid muaj pes tsawg leeg ntawm lawv cov cell membranes thiab cov yam ntxwv ntawm lub cell phab ntsa. Cov kab mob cell phab ntsa muaj peptidoglycan. Archaean cell phab ntsa tsis muaj peptidoglycan, tab sis lawv yuav muaj pseudopeptidoglycan, polysaccharides, glycoproteins, los yog protein-based cell phab ntsa
Vim li cas cov phab ntsa ntawm tes tsis muaj nyob hauv cov tsiaj hlwb?
Tsiaj cells tsis muaj cov phab ntsa ntawm tes vim lawv tsis xav tau. Cell phab ntsa, uas muaj nyob rau hauv cov nroj tsuag hlwb, tswj cov cell zoo li, yuav luag txhua cell muaj nws tus kheej exoskeleton. Qhov rigidity no tso cai rau cov nroj tsuag tuaj yeem sawv ntsug yam tsis xav tau cov pob txha
Cov kab mob dab tsi muaj cov phab ntsa ntawm tes nrog cov protein ntau carbohydrate?
Lub cell phab ntsa ntawm cov kab mob gram-zoo yog peptidoglycan macromolecule nrog cov khoom siv txuas ntxiv xws li teichoic acids, teichuronic acids, polyphosphates, lossis carbohydrates (302, 694)
