Kab mob morphology . Kab mob morphology deals nrog loj, puab, thiab kev npaj ntawm kab mob hlwb. Qhov loj ntawm Kab mob . Cov kab mob yog microscopic kab mob uas yog tsawg dua 3 micrometers (Μm) loj.
Raws li, peb hom kab mob morphology yog dab tsi?
Muaj peb pib cov duab ntawm kab mob : coccus, bacillus, thiab kauv. Raws li cov dav hlau ntawm kev faib, lub coccus puab tuaj yeem tshwm sim hauv ob peb txawv Kev npaj: diplococcus, streptococcus, tetrad, sarcina, thiab staphylococcus. Cov bacillus puab tuaj yeem tshwm sim li ib tus kab mob bacillus, streptobacillus, lossis coccobacillus.
Tsis tas li ntawd, lub hom phiaj ntawm kev kawm txog morphology ntawm cov kab mob yog dab tsi? Teb thiab piav qhia: Lub lub hom phiaj ntawm kev txheeb xyuas cov morphological Cov yam ntxwv ntawm cov kab mob microorganism yog los pab txheeb xyuas seb cov kab mob puas tuaj yeem yog.
Kuj kom paub, qhov txawv ntawm morphology thiab kev npaj ntawm cov kab mob yog dab tsi?
Morphology . Microbiologists kuj tuaj yeem txheeb xyuas kab mob los ntawm lawv cov colony morphology , los yog cov tsos thiab cov yam ntxwv ntawm lub kab mob thaj chaw. Thaum kev npaj hais txog cov pab pawg ntawm cov tib neeg lub hlwb, morphology piav txog cov tsos ntawm cov pab pawg ntawm kab mob , los yog colonies.
3 kab mob piv txwv yog dab tsi?
Piv txwv ntawm Kab Mob . Kab mob yog cov plural ntawm kab mob , uas yog microscopic one-celled organisms. Lawv pom nyob txhua qhov chaw thiab tuaj yeem ua rau muaj kev phom sij, xws li kis kab mob; los yog lawv tuaj yeem muaj txiaj ntsig zoo, xws li hauv fermentation lossis decomposition. Tsib hom kab mob yog: Coccus, Bacillus, Spirillum, Rickettsia, thiab Mycoplasma.

Cov kab mob puas kis cov kab mob eukaryotic?
Ib lub cell uas muaj kab mob ua rau cov kab mob kis tau ntau dua thiab cov khoom siv caj ces es tsis yog nws cov khoom qub. Qee cov kab mob yuav nyob twj ywm hauv cov tswv tsev rau lub sijhawm ntev, ua rau tsis muaj kev hloov pauv hauv lawv cov tswv tsev (ib theem hu ua lysogenic theem). Cov kab mob ua rau muaj ntau yam kab mob hauv eukaryotes
Cov tshuaj tua kab mob twg thaiv cov kab mob protein ntau?
Tetracyclins yog ib hom tshuaj tua kab mob uas suav nrog cov thawj tetracycline nrog rau doxycycline thiab minocycline. Cov tshuaj tua kab mob no khi rau A qhov chaw ntawm 30s ribosome, tiv thaiv tRNA los ntawm kev nqa cov amino acids tshiab. Yog tias tRNA tsis tuaj yeem txuas mus rau ribosome, ces tsis muaj cov proteins tshiab tuaj yeem ua tau
Cov kab mob twg muaj cov kab mob eukaryotic?
Cov kab mob thiab Archaea tsuas yog prokaryotes. Cov kab mob uas muaj eukaryotic hlwb hu ua eukaryotes. Tsiaj txhu, nroj tsuag, fungi, thiab protists yog eukaryotes. Tag nrho cov kab mob multicellular yog eukaryotes
Cov kab mob thiab cov kab mob ua haujlwm zoo li cas?
Ob leeg cov kab mob thiab cov kab mob muaj cov phab ntsa ntawm tes (txawm hais tias sib txawv hauv cov qauv thiab muaj pes tsawg leeg) Feem ntau cov kab mob thiab cov kab mob tau txais lub zog los ntawm kev ua pa aerobic (ua pa hauv cov kab mob me ntsis txawv dua li hauv Eukaryotes tab sis cov pa oxygen ib txwm xav tau rau oxidise suab thaj, hauv dej kawg. thiab carbon dioxide yog tsim)
Vim li cas cov kab mob Gram tsis zoo tshwm liab liab thaum cov kab mob Gram zoo pom ntshav liab?
Gram zoo hlwb stain ntshav vim lawv cov peptotidoglycan txheej yog tuab txaus, txhais tau tias tag nrho cov kab mob Gram zoo yuav khaws lawv cov stain. Gram tsis zoo hlwb stain liab vim lawv muaj ib tug nyias peptidoglycan phab ntsa, thiab lawv yuav tsis khaws ib yam ntawm cov ntshav stain los ntawm crystal violet
