Qhov txawv ntawm cov kab mob thiab cov mollicutes yog cov kab mob feem ntau muaj peptidoglycan cell phab ntsa thaum mollicutes yog cov kab mob uas tsis muaj phab ntsa ntawm tes.
Cov kab mob yog cov kab mob uas muaj ntau tshaj plaws nyob rau hauv cov xwm txheej. Lawv yog ib pawg ntawm cov kab mob unicellular uas nyob txhua qhov chaw. Tsis tas li ntawd, lawv yog cov kab mob prokaryotic. Yog li ntawd, lawv tsis muaj ib tug nucleus thiab membrane-bound organelles. Muaj cov kab mob sib txawv. Qee tus ntawm lawv yog cov kab mob photosynthetic hu ua cyanobacteria. Feem ntau, cov kab mob feem ntau muaj cov phab ntsa ntawm tes. Txawm li cas los xij, qee pawg kab mob tsis muaj cov phab ntsa ntawm tes. Mollicutes yog cov kab mob zoo li no uas tsis muaj phab ntsa ntawm tes. Li no, kab lus no tham txog qhov sib txawv ntawm cov kab mob thiab cov mollicutes.
Cov kab mob yog dab tsi?
Cov kab mob yog cov kab mob prokaryotic microscopic muaj nyob txhua qhov chaw. Tsis tas li ntawd, lawv yog cov kab mob unicellular uas muaj lub koom haum cellular yooj yim. Lawv tsis muaj cov nucleus lossis membrane-bound tseeb organelles xws li mitochondria, Golgi lub cev, ER, thiab lwm yam. Tsis tas li ntawd, lawv tuaj yeem muaj nyob hauv ib lub xovtooj ntawm tes lossis ua pawg. Ntxiv mus, lawv tuaj yeem muaj ntau yam duab: coccus, bacillus, spirillum, thiab lwm yam. Tsis tas li ntawd, lawv muaj cov phab ntsa ntawm tes uas muaj cov txheej txheem peptidoglycan tshwj xeeb. Txawm tias lub thickness ntawm no peptidoglycan txheej hloov ntawm cov kab mob. Raws li qhov ntawd, muaj ob pawg kab mob xws li Gram-negative thiab Gram-positive.
Cov kab mob me me feem ntau yog los ntawm binary fission, uas yog hom kev yug menyuam tsis muaj menyuam. Lwm yam tshaj li binary fission, lawv siv ntau txoj kev sib deev kev sib deev xws li kev sib txuas, hloov pauv thiab hloov pauv, thiab lwm yam.
Daim duab 01: Kab mob
Cov kab mob muaj cov genome me uas tsim los ntawm ib qho chromosome hauv cytoplasm. Lawv cov noob muaj nyob raws li operons, uas yog pawg qhia nyob rau hauv ib qho kev txhawb nqa. Sib nrug los ntawm chromosome, qee cov kab mob muaj cov DNA ntxiv-chromosomal hauv daim ntawv ntawm plasmids. Plasmids yog me me ncig kaw DNA. Lawv tsis yog ib qho tseem ceeb rau kev ciaj sia ntawm cov kab mob, tab sis lawv muab cov txiaj ntsig zoo ntxiv rau cov kab mob vim tias lawv muaj cov noob tshwj xeeb. Piv txwv li, cov tshuaj tiv thaiv kab mob muaj nyob hauv plasmid DNA ntawm cov kab mob.
Cov kab mob feem ntau yog nonpathogenic. Txawm li cas los xij, ib feem me me ua rau muaj kab mob xws li kab mob ntsws, tuberculosis, botulism, typhoid, cholera, diphtheria, kab mob meningitis, tetanus, Lyme disease, gonorrhoea, thiab syphilis.
Mollicutes yog dab tsi?
Mollicutes yog ib chav ntawm cov kab mob uas tsis muaj phab ntsa ntawm tes. Hauv cov lus yooj yooj yim, lawv yog cov kab mob tsis muaj phab ntsa. Tsis tas li ntawd, lawv muaj cov genome me me piv rau lwm cov kab mob. Lawv cov genome nyob nruab nrab ntawm 580 kb txog 2200 kb. Mycoplasma yog ib qho zoo tshaj plaws-paub mollicutes. Lwm ob pawg yog Spiroplasma thiab Acholeplasma. Mollicutes yog cov kab mob yooj yim tshaj plaws thiab tsawg tshaj plaws.
Daim duab 02: Mollicute – Mycoplasma
Tsis zoo li lwm cov kab mob, mollicutes yog kab mob ntawm cov tsiaj thiab nroj tsuag. Lawv nyob nrog cov kab mob hauv lub cev thiab muab cov khoom noj uas ua rau muaj kab mob. Yog li, lawv yog cov nroj tsuag thiab tsiaj cov kab mob. Hauv tib neeg, hom Mycoplasma feem ntau yog colonize mucosal chaw xws li ua pa thiab qhov chaw mos.
Dab tsi yog qhov zoo sib xws ntawm Bacteria thiab Mollicutes?
- Mollicutes yog ib chav ntawm cov kab mob uas tsis muaj phab ntsa ntawm tes.
- Ob tus kab mob thiab mollicutes yog prokaryotes thiab ib leeg-cell kab mob.
- Lawv tsis muaj daim nyias nyias nyias organelles.
- Lawv tsis muaj nucleus.
- Tsis tas li ntawd, lawv muaj ib lub genome me uas tsim los ntawm ib qho chromosome.
- Ob tus kab mob thiab mollicutes nqa tawm binary fission.
- Qee cov kab mob thiab mollicutes yog cov nroj tsuag thiab tsiaj kab mob.
Qhov txawv ntawm Kab Mob thiab Mollicutes yog dab tsi?
Cov kab mob yog cov kab mob ib leeg-celled prokaryotic uas muaj cov phab ntsa ntawm tes. Lub caij no, mollicutes yog ib pawg ntawm cov kab mob uas tsis muaj cov phab ntsa ntawm tes. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm cov kab mob thiab cov mollicutes. Tsis tas li ntawd, cov kab mob genome yog qhov sib piv loj dua qhov loj ntawm cov genome ntawm mollicutes. Yog li, lawv qhov loj me kuj yog qhov sib txawv ntawm cov kab mob thiab cov mollicutes. Ntxiv mus, mollicutes feem ntau yog cov kab mob cab nyob ntawm tus tswv tsev rau cov as-ham, tsis zoo li cov kab mob.
Cov duab hauv qab no qhia cov ntsiab lus ntxiv ntawm qhov sib txawv ntawm cov kab mob thiab cov mollicutes.
Summary – Bacteria vs Mollicutes
Cov kab mob yog cov kab mob nyob txhua qhov chaw. Lawv yog cov kab mob unicellular uas muaj lub koom haum ntawm tes yooj yim tshaj plaws. Cov kab mob muaj cov phab ntsa txhav ntawm tes uas muaj peptidoglycan. Tab sis, mollicutes yog ib chav ntawm cov kab mob uas tsis muaj cov phab ntsa ntawm tes. Hauv kev xaus, qhov no yog qhov sib txawv tseem ceeb ntawm cov kab mob thiab cov mollicutes. Tsis tas li ntawd, mollicutes muaj cov genome me dua li lwm cov kab mob. Qhov no yog ib tug yam ntxwv feature ntawm mollicutes. Tsis tas li ntawd, mollicutes yog nyob ntawm tus tswv tsev. Lawv tau txais cov khoom noj los ntawm tus tswv tsev, ua rau muaj kab mob.
