Qhov sib txawv tseem ceeb ntawm cov kab mob eukaryotic thiab prokaryotic yog cov kab mob eukaryotic muaj qhov tseeb nucleus thiab membrane-bound organelles thaum cov kab mob prokaryotic tsis muaj nucleus thiab membrane-bound organelles.
Txhua yam kab mob muaj sia muaj nyob rau ob pawg uas yog prokaryotes lossis eukaryotes. Cov kab mob Prokaryotic nthuav tawm lub koom haum ntawm tes yooj yim thaum cov kab mob eukaryotic qhia txog lub koom haum cell complex. Ntxiv mus, prokaryotes yog unicellular, thiab lawv tsis muaj ib tug nucleus thiab membrane-bound organelles. Ntawm qhov tod tes, eukaryotes feem ntau yog cov cellular thiab muaj cov nucleus tseeb thiab cov kab mob sib txuas ua ke xws li chloroplasts, mitochondria thiab Endoplasmic reticulum, thiab lwm yam. Prokaryotes suav nrog cov kab mob thiab Archaea thaum eukaryotes suav nrog protists, fungi, nroj tsuag thiab tsiaj txhu. Dua li ntawm qhov sib txawv saum toj no, muaj ntau qhov sib txawv ntawm prokaryotes thiab eukaryotes. Yog li ntawd, kev nkag siab qhov sib txawv ntawm cov kab mob prokaryotic thiab eukaryotic yog qhov tseem ceeb heev. Lub hom phiaj ntawm tsab xov xwm no yog los tham txog qhov sib txawv ntawm eukaryotic thiab prokaryotic kab mob.
YEukaryotic yog dab tsi?
Cov kab mob Eukaryotic muaj cov kab mob sib koom ua ke nrog cov kab mob sib txuas nrog cov kab mob uas tau hais tseg. Tag nrho cov nroj tsuag, tsiaj txhu, fungi, protozoa thiab algae yog cov kab mob eukaryotic. Lawv muaj 80S loj ribosomes nyob rau hauv cytoplasm uas ua raws li qhov chaw rau cov proteins synthesis. Thiab lawv kuj muaj mitochondria, Golgi lub cev, ER, thiab chloroplast, thiab lwm yam. Yog li ntawd, lub hnab ntawv nuclear yog tus yam ntxwv tshaj plaws ntawm txhua yam kab mob eukaryotic. Nuclear membrane encloses lub nucleus ntawm eukaryotes. Lub genome ntawm eukaryotes yog nruj nreem khi nrog cov proteins histone thiab ntim rau hauv chromosomes uas yog cov txheej txheem nyuaj heev.
Daim duab 01: Eukaryotes
Eukaryotes suav nrog cov kab mob yooj yim thiab nyuaj. Lawv kev yug me nyuam tuaj yeem yog kev sib deev lossis asexual. Kev sib deev kev sib deev yog tam sim no tsuas yog ntawm cov eukaryotes, thiab qhov ntawd suav nrog cov kauj ruam tseem ceeb ntawm meiosis hauv cell faib. Los ntawm qhov ntawd txhais tau tias kev sib deev kev sib deev tau tso cai rau cov noob pauv los tsim cov yam ntxwv tshiab raws li kev hloov pauv rau lub ntiaj teb hloov pauv. Txawm li cas los xij, qhov sib txawv ntawm cov kab mob eukaryotic yog tsawg heev; e.g. Hauv tib neeg lub cev, muaj kaum npaug ntau dua prokaryotes ntau dua li lub cev hlwb.
YProkaryotic yog dab tsi?
"Pro" txhais tau tias ua ntej, thiab "karyone" txhais tau tias rooj plaub hauv Greek, ua rau lub sij hawm prokaryote. Qhov piv txwv zoo tshaj plaws los qhia cov prokaryotes yog cov kab mob. Cov kab mob prokaryotic feem ntau yog unicellular thiab tsis tshua muaj ntau lub cellular. Prokaryotes tsis muaj nucleus. Tsis tas li ntawd, lawv tsis muaj organelles khi nrog daim nyias nyias. Txawm li cas los xij, lawv muaj 70S me ribosomes hauv cytoplasm. Lawv muaj ib tug nucleoid nrog cov strands tsis zoo DNA complex nyob rau hauv lub cytoplasm. Tsuas muaj ib lub voj ntawm chromosomal DNA hauv nucleoid. Txawm li cas los xij, lawv muaj cytoskeleton primitive rau kev saib xyuas ntawm cov duab ntawm tes.
Qhov sib piv ntawm thaj chaw-rau-ntim yog siab heev hauv cov prokaryotes uas ua rau muaj qhov metabolic siab, uas ua rau muaj kev loj hlob ntxiv. Yog li ntawd, lub sij hawm tiam ntawm prokaryotes yog luv heev. Lawv tuaj yeem tsim cov zej zog sib sau ua ke, hu ua colonies uas qhia txog kev sib raug zoo ntawm cov kab mob prokaryotic. Biofilms yog cov piv txwv tseem ceeb ntawm lawv txoj kev ua neej nyob, thiab cov kws tshawb fawb ntseeg tias cov tshuaj tiv thaiv kab mob siab dua hauv biofilms.
Daim duab 02: Prokaryotes
Ntxiv mus, cov duab prokaryotic feem ntau yog plaub lub npe hu ua Coccus, Bacillus, Spirocheate, thiab Vibrio. Lawv rov tsim dua ntawm asexual txhais tau tias xws li binary fission thiab budding. Txawm li cas los xij, kev hloov pauv noob tshwm sim los ntawm cov kab mob sib txuas. Tib neeg yeej tsis tuaj yeem tso tseg kev kawm cov prokaryotes, vim nws yuav luag tsis tuaj yeem ntsuas qhov sib txawv ntawm txhua qhov ntsuas.
Qhov Zoo sib xws ntawm Eukaryotic thiab Prokaryotic yog dab tsi?
- Eukaryotic thiab prokaryotic kab mob yog cov kab mob nyob.
- Lawv muaj cov hlwb.
- Kuj, ob leeg yug, loj hlob thiab tuag.
- Dhau li, ob leeg ua ntau yam txheej txheem metabolic.
Qhov txawv ntawm Eukaryotic thiab Prokaryotic yog dab tsi?
Eukaryotic hlwb muaj cov nucleus thiab membrane-bound organelles thaum cov hlwb prokaryotic tsis muaj cov nucleus thiab membrane-bound organelles. Peb tuaj yeem xav txog qhov no yog qhov sib txawv tseem ceeb ntawm cov kab mob eukaryotic thiab prokaryotic. Tsis tas li ntawd, lwm qhov sib txawv ntawm cov kab mob eukaryotic thiab prokaryotic yog cov eukaryotes tuaj yeem yog unicellular lossis multicellular thaum tag nrho cov prokaryotes yog unicellular.
Ntxiv mus, eukaryotes muaj 80S ribosomes thaum prokaryotes muaj 70S ribosomes. Yog li, nws yog lwm qhov sib txawv ntawm eukaryotic thiab prokaryotic. Tsis tas li ntawd, qhov sib txawv ntxiv ntawm cov kab mob eukaryotic thiab prokaryotic yog cov eukaryotes muaj ntau cov chromosomes thaum cov prokaryotes muaj tib chromosome.
Hauv qab infographic ntawm qhov sib txawv ntawm eukaryotic thiab prokaryotic qhia ntau qhov sib txawv ntawm ob yam kab mob.
Summary – Eukaryotic vs Prokaryotic
Cov kab mob nyob hauv tuaj yeem yog prokaryotes lossis eukaryotes. Prokaryotes yog cov kab mob yooj yim thiab me me thaum eukaryotes yog cov kab mob loj thiab nyuaj. Qhov sib txawv tseem ceeb ntawm cov kab mob eukaryotic thiab prokaryotic yog qhov muaj thiab tsis muaj cov nucleus hauv lawv cov hlwb. Eukaryotes muaj qhov tseeb membrane-bound nucleus thaum prokaryotic tsis muaj nucleus. Tsis tas li ntawd, eukaryotes muaj cov membrane-bound organelles thaum prokaryotes tsis muaj membrane-bound organelles. Tsis tas li ntawd, eukaryotes muaj 80S ribosomes thaum prokaryotes muaj 70S ribosomes. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm cov kab mob eukaryotic thiab prokaryotic.
