Qhov sib txawv tseem ceeb ntawm cyanobacteria thiab algae yog tias cyanobacteria yog ib pawg ntawm cov kab mob prokaryotic thaum algae yog cov kab mob me me zoo li cov nroj tsuag eukaryotic.
Photosynthesis yog txheej txheem tseem ceeb heev uas hloov lub zog ntawm lub hnub ci mus rau hauv lub zog tshuaj ntawm carbohydrates. Li no, nws yog cov txheej txheem uas tso cai rau qee yam kab mob los ua lawv cov zaub mov, thiab cov kab mob no hu ua photoautotrophs. Ib yam li ntawd, cov nroj tsuag ntsuab, algae thiab cyanobacteria yog peb hom photoautotrophs. Ntawm peb hom no, cyanobacteria yog prokaryotes, uas yog cov kab mob. Ntawm qhov tod tes, cov nroj tsuag ntsuab thiab algae yog cov kab mob eukaryotic. Thaum xav txog cyanobacteria thiab algae, lawv yog cov kab mob microscopic, tsis zoo li cov nroj tsuag ntsuab. Txawm li cas los xij, cyanobacteria thiab algae txawv ntawm ib leeg los ntawm lub koom haum cellular. Lub hom phiaj ntawm kab lus no yog piav qhia qhov txawv ntawm cyanobacteria thiab algae.
Cyanobacteria yog dab tsi?
Cyanobacteria yog ib pawg kab mob. Lawv qhov tshwj xeeb yog lub peev xwm ntawm photosynthesis. Lawv tshwm hauv cov xim xiav-ntsuab, thiab lawv tseem hu ua cov kab mob xiav-ntsuab. Cyanobacteria siv cov pa roj carbon dioxide ua cov pa roj carbon. Ntxiv mus, photosynthesis thawj evolved hauv cov kab mob. Yog li ntawd, nws yog qhov zoo tshaj plaws uas photosynthesis yog thawj evolved hauv cyanobacteria. Yog li, cov kab mob xiav, ntsuab muaj nyob hauv cov khaubncaws sab nraud povtseg ntawm cov dej hiav txwv thiab hauv cov khaubncaws sab nraud povtseg ntawm cov dej tshiab. Lawv kuj muaj nyob rau ntawm cov av ntxoov ntxoo, pob zeb, av nkos, ntoo thiab txawm nyob rau qee yam kab mob.
Feem ntau ntawm cov kab mob cyanobacteria yog cov ntaub ntawv unicellular. Tab sis qee tus tau ua ke los tsim cov filaments uas tau ntim los ntawm mucous. Ob qho piv txwv zoo rau qhov xwm txheej no yog Anabaena thiab Spirulina. Cyanobacteria txawv ntawm ntau lwm cov kab mob. Ntau lossis tsawg dua lawv zoo li cov nroj tsuag thiab algae vim lawv tuaj yeem tsim cov pa oxygen los ntawm dej thaum lub sijhawm photosynthesis. Photosynthetic pigments ntawm cyanobacteria muaj nyob rau ntawm photosynthetic daim nyias nyias. Photosynthetic membranes khiav thoob plaws hauv cytoplasm. Chlorophyll a yog ib qho tseem ceeb ntawm photosynthetic pigments muaj nyob rau hauv cyanobacteria. Tsis tas li ntawd, lawv muaj phycocyanin, uas yog xim xiav-ntsuab. Cells ntawm cov kab mob xiav-ntsuab yog feem ntau loj dua li lwm cov kab mob.
Daim duab 01: Cyanobacteria
Ntxiv mus, qee cov kab mob cyanobacteria tuaj yeem kho nitrogen los ntawm cov cua mus rau hauv ammonia. Ammonia ces koom nrog hauv cov amino acid synthesis hauv lawv. Rau lub hom phiaj no, cyanobacteria muaj lub cell tshwj xeeb hu ua heterocysts. Anabaena thiab Nostoc yog ob hom nitrogen-fixing cyanobacteria.
Algae yog dab tsi?
Algae yog cov kab mob zoo li cov nroj tsuag uas yooj yim tshaj plaws nyob rau hauv ib puag ncig dej, thiab zoo li cov nroj tsuag siab dua los ntawm qhov muaj chlorophyll thiab ua photoautotrophic. Cov algae tseem ceeb heev yog unicellular, tab sis nrog evolution, lawv tau tsim mus rau hauv multicellular cov ntaub ntawv, uas muaj ntsug thiab kab rov tav tshuab. Txawm tias tam sim no algae pom nyob rau hauv kev koom tes nrog cov av ntub dej thiab dej ib puag ncig, ob qho tib si dej tshiab thiab dej hiav txwv.
Muaj ntau pab pawg ntawm algae. Hauv kev faib tawm yav dhau los, algae suav nrog 6 pawg. Cov no yog chlorophytes nrog rau ntsuab algae, euglenophytes, pyrrophyts, chrysophytes, phaeophytes nrog rau xim av algae thiab rhodophytes nrog rau liab algae. Algae raws li ib pawg ntawm cov nroj tsuag qhia ib tug dav variation nyob rau hauv morphology. Lawv tsis tsuas yog microscopic tab sis kuj macroscopic. Lawv lub cev cog tuaj yeem yog unicellular, uninucleate, lossis unicellular multinucleate lossis multicellular multinucleate cov ntaub ntawv. Yuav luag tag nrho cov ntaub ntawv multicellular qhia ib lub cev tsis sib xws hu ua thallus. Cov duab ntawm cov nroj tsuag tuaj yeem yog filamentous, thalloid, ntiaj teb zoo li, flattened los yog heterotrichous cov ntaub ntawv.
Daim duab 02: Algae
Qee algae yog motile thaum qee qhov tsis txav. Qee qhov txuas nrog lub substrate nrog kev pab los ntawm kev tuav pov hwm. Algae qhia cov xim sib txawv vim lawv muaj cov xim sib txawv. Cov ntaub ntawv Unicellular qhia ntau qhov sib txawv ntawm lawv qhov loj thiab cov duab ntawm chloroplast. Colony cov ntaub ntawv ntawm algae muaj nyob rau hauv cov dej tshiab. Cov no yog cov sib sau ua ke ntawm cov hlwb uas muaj cov lej tas li. Kev yug me nyuam hauv algae yog qhov nyuaj vim lawv qhia txog kev yug me nyuam nrog rau kev sib deev.
Dab tsi zoo sib xws ntawm Cyanobacteria thiab Algae?
- Cyanobacteria thiab algae yog cov kab mob photosynthetic.
- Yog li, lawv tuaj yeem hloov lub hnub ci mus rau hauv carbohydrates thiab, lawv ob leeg muaj chlorophyll a.
- Tsis tas li ntawd, ob qho tib si feem ntau yog cov kab mob hauv dej.
- Tsis tas li, lawv yog thawj cov tsim khoom ntawm cov dej hauv dej.
- Dhau li ntawd, muaj cov tswvcuab unicellular hauv ob pawg.
Qhov txawv ntawm Cyanobacteria thiab Algae yog dab tsi?
Cyanobacteria yog ib pawg ntawm cov kab mob prokaryotic uas tuaj yeem ua rau photosynthesize. Ntawm qhov tod tes, algae yog cov nroj tsuag me me zoo li cov kab mob eukaryotic. Qhov no yog qhov sib txawv tseem ceeb ntawm cyanobacteria thiab algae. Tsis tas li ntawd, cyanobacteria yog unicellular thaum algae feem ntau yog unicellular thaum muaj ntau ntau hom ntawv zoo li. Yog li, nws yog qhov sib txawv tseem ceeb ntawm cyanobacteria thiab algae. Ib qho ntxiv ntawm qhov sib txawv ntawm cyanobacteria thiab algae yog tias cyanobacteria zwm rau lub nceeg vaj Monera thaum algae zwm rau lub nceeg vaj Protista.
Tsis tas li ntawd, cyanobacteria tsis muaj cov kab mob sib txuas thiab cov nucleus. Txawm li cas los xij, algae muaj cov kab mob sib txuas nrog cov organelles thiab cov nucleus. Yog li, nws yog qhov sib txawv ntxiv ntawm cyanobacteria thiab algae. Qhov tseem ceeb tshaj plaws, cyanobacteria tuaj yeem kho atmospheric nitrogen thaum algae tsis tuaj yeem kho nitrogen. Li no, qhov no kuj yog qhov sib txawv ntawm cyanobacteria thiab algae.
Hauv qab infographic ntawm qhov sib txawv ntawm cyanobacteria thiab algae qhia qhov sib txawv ntawm qhov sib piv.
Summary – Cyanobacteria vs Algae
Cyanobacteria thiab algae yog cov kab mob photosynthetic. Txawm li cas los xij, cyanobacteria yog cov kab mob prokaryotic thaum algae yog cov kab mob eukaryotic. Qhov no yog qhov sib txawv tseem ceeb ntawm cyanobacteria thiab algae. Tsis tas li ntawd, cyanobacteria tsis muaj qhov tseeb nucleus thiab membrane-bound organelles. Tab sis, algae muaj tseeb nucleus thiab membrane-bound organelles xws li chloroplasts, mitochondria, thiab lwm yam. Tsis tas li ntawd, cyanobacteria muaj chlorophyll a, phycocyanin thiab phycoerythrin thaum algae muaj chlorophyll a thiab b, carotenoids thiab xanthophylls. Nov yog cov ntsiab lus ntawm qhov sib txawv ntawm cyanobacteria thiab algae.
