Cov kab mob zoo li eukaryotic tshuaj cell nyob rau hauv uas lawv muaj cytoplasm , ribosomes, thiab a plasmembrane . Txhim kho qhov sib txawv ntawm cov kab mob cell los ntawm eukaryotic cell suav nrog cov DNA ncig ntawm cov nucleoid, qhov tsis muaj daim nyias nyias - khi organelles, lub cell phab ntsa ntawm peptidoglycan, thiab flagella.
Hauv qhov no, dab tsi yog qhov ntawm cov kab mob ntawm tes thiab lawv txoj haujlwm?
Table 2. Cov ntsiab lus ntawm cov yam ntxwv ntawm cov kab mob bacterialcellstructures
| Qauv Flagella | Function(s) Kev ua luam dej |
|---|---|
| Ribosomes | Sites of translation (protein synthesis) |
| suav nrog | Feem ntau reserves ntawm cov as-ham; ntxiv tshwj xeeb ua haujlwm |
| Chromosome | Genetic khoom ntawm cell |
| Plasmid | Extrachromosomal genetic khoom |
Tsis tas li ntawd, cov qauv dab tsi muaj nyob rau hauv cov kab mob hlwb? Nws yog gel zoo li matrix uas muaj dej, enzymes, as-ham, pov tseg, thiab roj thiab muaj cellstructures xws li ribosomes, chromosome, thiab plasmids. Cov cell hnab ntawv encases lub cytoplasm thiab tag nrho nws cov Cheebtsam. Unlike theeukaryotic (tseeb) hlwb , kab mob tsis muaj amembrane enclosed nucleus.
Kuj paub, kab mob thiab nws cov qauv yog dab tsi?
Qauv . Kab mob (singular: kab mob ) yog cais raws li prokaryotes, uas yog ib leeg-celled kab mob nrog ib tug yooj yim sab hauv qauv uas tsis muaj ib tug nucleus, thiab muaj DNA uas yog floats dawb do nyob rau hauv twisted, xov-zoo li loj hu ua tus nucleoid, los yog sib cais, lub voj voog hu ua plasmids.
Cov kab mob ua haujlwm li cas?
Kab mob nyob rau hauv digestive system breakdownnutrients, xws li complex suab thaj, rau hauv cov ntaub ntawv lub cev canuse. Non-hazardous kab mob kuj pab tiv thaiv kab mobbyoccupying qhov chaw uas cov pathogenic, ordisease-ua rau, kab mob xav txuas rau. Ib txhia kab mob tiv thaiv peb ntawm kab mob los ntawm kev tawm tsam cov kab mob.

Cov kab lus hloov sab hauv cov ces kaum piav qhia txoj haujlwm ntawm ob lub kaum sab xis li cas?
Hloov sab hauv cov ces kaum yog tsim los ntawm ib tug transversal intersecting ob parallel kab. Lawv nyob nruab nrab ntawm ob qho tib si kab tab sis nyob rau sab nraud ntawm lub transversal, tsim ob khub (plaub tag nrho cov ces kaum) ntawm cov ces kaum sab hauv. Hloov cov ces kaum sab hauv yog congruent, txhais tau tias lawv muaj qhov sib npaug
Cov nqe lus twg zoo tshaj plaws piav qhia txog qhov tseem ceeb ntawm cov lus qhia muaj nuj nqis?
Qhov tsis suav nrog tus nqi ntawm ib qho kev qhia rational yog qhov tseem ceeb uas tus denominator ntawm qhov kev qhia yog xoom. Tsis tas li ntawd, tus naj npawb ntawm zeros ntawm ib tug polynomial yeej ib txwm tsawg dua los yog sib npaug rau degree ntawm lub polynomial. Yog li ntawd, tus naj npawb ntawm cov txiaj ntsig tsis suav nrog cov lus qhia muaj txiaj ntsig tsis tuaj yeem tshaj li qib ntawm tus lej
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)
Dab tsi yog cov kab mob piav qhia cov kab mob ntawm tes hauv kev nthuav dav?
Cov kab mob yog cov prokaryotes, tsis muaj cov nuclei zoo thiab cov kab mob sib txuas ua ke, thiab nrog cov chromosomes tsim los ntawm ib lub voj voog DNA kaw. Lawv tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, los ntawm feeb spheres, cylinders thiab kauv threads, rau flagellated rods, thiab filamentous chains
Vim li cas ecologists nug cov lus nug txog cov xwm txheej thiab cov kab mob uas muaj ntau?
Vim li cas Ecologist nug cov lus nug txog cov xwm txheej thiab cov kab mob uas muaj qhov sib txawv ntawm ib tus neeg mus rau Biosphere? Txhawm rau nkag siab txog kev sib raug zoo hauv biosphere, ecologists nug cov lus nug txog cov xwm txheej thiab cov kab mob uas muaj qhov nyuaj ntawm ib tus neeg mus rau tag nrho biosphere
