Qhov Tseem Ceeb Qhov txawv - Cov kab mob vs Cyanobacteria
Cov kab mob thiab cyanobacteria yog cov kab mob prokaryotic. Cyanobacteria yog cov kab mob loj tshaj plaws uas pom muaj nyob hauv dej hiav txwv. Ob pawg muaj xws li unicellular microscopic kab mob, thiab ob leeg muaj ib tug yooj yim lub cev qauv. Cyanobacteria muaj cov yam ntxwv xiav-ntsuab xim vim nws cov xim tshwj xeeb. Lawv raug hu ua xiav-ntsuab algae ib yam nkaus. Qee cov kab mob muaj peev xwm photosynthesize. Tab sis feem ntau ntawm cov kab mob yog heterotrophs. Cyanobacteria muaj peev xwm ntawm photosynthesizing. Qhov sib txawv tseem ceeb ntawm cov kab mob thiab cyanobacteria yog cov kab mob tsis tsim cov pa dawb thaum lawv cov photosynthesis thaum cyanobacteria muaj peev xwm tsim cov pa dawb thaum lub sijhawm photosynthesis.
Cov kab mob yog dab tsi?
Cov kab mob yog cov kab mob uas muaj ntau tshaj plaws nyob rau hauv cov xwm txheej. Lawv muab faib rau txhua qhov chaw. Yog li ntawd lawv thiaj li hu ua ubiquitous organisms. Cov kab mob muaj nyob rau hauv pawg prokaryotic. Lawv tsis muaj cov nucleus thiab cov membrane-bound tseeb organelles xws li mitochondria, Golgi lub cev, ER thiab lwm yam. Cov kab mob yog unicellular thiab muaj ib tug yooj yim cell qauv. Tej zaum lawv yuav pom nyob rau hauv ib lub xov tooj ntawm tes los yog raws li cov cheeb tsam. Cov kab mob muaj cov phab ntsa ntawm tes uas muaj cov kab mob tshwj xeeb peptidoglycan txheej. Raws li cov thickness ntawm peptidoglycan txheej, cov kab mob tau muab faib ua ob pawg loj; Gram's negative thiab Gram's positive Bacteria. Cov kab mob muaj flagella rau qhov chaw. Lawv multiply los ntawm binary fission. Binary fission yog ib hom ntawm asexual reproduction. Conjugation, transformation thiab transduction yog kev sib deev txoj kev sib deev siv los ntawm cov kab mob kom nce cov xov tooj ntawm tes. Cov kab mob tuaj yeem muaj ntau yam duab; coccus, Bacillus, spirillum, thiab lwm yam.
Cov kab mob genome me me thiab muaj tib chromosome hauv cytoplasm. Thiab lawv DNA tsis cuam tshuam nrog histone proteins. Lawv tuaj yeem muaj cov DNA ntxiv-chromosomal hauv daim ntawv ntawm plasmids. Cov noob ntawm cov kab mob no pom tau ua ke ua ke ua operons. Kev nthuav qhia ntawm operon yog tswj hwm los ntawm ib tus neeg txhawb nqa. Qee cov noob tseem ceeb uas muab cov kab mob sib txawv zoo muaj nyob hauv plasmids. Piv txwv li, feem ntau ntawm cov tshuaj tiv thaiv kab mob yog nyob rau hauv plasmid DNA. Cov kab mob muaj ribosomes ntawm 70 S, tsis zoo li hauv eukaryotes. Cov kab mob sib txuas lus nrog lwm tus los ntawm kev paub txog pawg neeg.

Feem ntau ntawm cov kab mob no yog nonpathogenic. Txawm li cas los xij, qee cov kab mob ua rau muaj kab mob xws li kab mob ntsws, tuberculosis, botulism, typhoid, cholera, diphtheria, kab mob meningitis, tetanus, Lyme disease, gonorrhea, thiab syphilis.
Cyanobacteria yog dab tsi?
Cyanobacteria yog lub npe hu ua cov kab mob photosynthetic. Lawv yog cov kab mob loj tshaj plaws hauv cov dej hauv dej. Lawv kuj tuaj yeem pom hauv av, pob zeb thiab feem ntau cov chaw nyob. Cov pab pawg no muaj txog 1500 hom. Lawv kuj raug hu ua xiav-ntsuab algae vim nws cov yam ntxwv xiav-ntsuab xim. Cov xim no yog vim cov xim xiav-ntsuab; phycocyanin tshuaj. Cyanobacteria muaj cov xim photosynthetic feem ntau yog chlorophyll a. Yog li ntawd, lawv muaj peev xwm ntawm photosynthesizing thiab tso pa dawb oxygen rau ib puag ncig. Lawv tsim lawv tus kheej cov khoom noj yog li lawv yog cov kab mob autotrophic. Cov qauv ntawm cyanobacteria yog qhov yooj yim thiab feem ntau yog unicellular lossis filamentous. Lawv nyob ua colonies los yog aggregates. Cyanobacteria yog cov kab mob prokaryotic, thiab lawv tsis muaj qhov tseeb organelles xws li mitochondria thiab chloroplasts.
Cyanobacteria yog tus tsim ntawm atmospheric oxygen thaum pib ntawm lub neej hauv ntiaj teb. Lawv kuj muaj peev xwm kho atmospheric nitrogen thiab txhawb cov nroj tsuag rau nitrogen yuav tsum tau. Hauv kev ua liaj ua teb, cyanobacteria yog siv los ua nitrogen chiv vim muaj peev xwm no. Kev kho nitrogen yog ua los ntawm cov qauv hu ua heterocyst ntawm cyanobacteria. Cyanobacteria qhia txog kev yug me nyuam asexual. Nws yog ua tiav los ntawm fission. Lawv muaj peev xwm nyob hauv ib puag ncig huab cua. Kev ciaj sia yog txhawb nqa los ntawm cov qauv hu ua akinetes. Akintes yog tuab phab ntsa thiab muaj peev xwm tiv taus desiccation thiab khov.
Daim duab 02: Cyanobacteria
Cyanobacteria yog tshwm sim los ntawm kev ua qias tuaj ntawm cov dej nyob ib puag ncig. Vim muaj ntau tshaj nitrogen thiab phosphorus, algal blooms tuaj yeem tsim. Cov algal blooms feem ntau yog tsim los ntawm cyanobacteria. Qhov tshwm sim no hu ua eutrophication.
