Qhov sib txawv tseem ceeb ntawm cov hlwb eukaryotic thiab cov hlwb prokaryotic yog tias cov hlwb eukaryotic muaj cov nucleus tseeb thiab cov kab mob sib xyaw ua ke tiag tiag thaum cov cell prokaryotic tsis muaj cov nucleus lossis cov organelles tseeb.
Cells yog qhov tseem ceeb hauv kev tsim txhua yam nyob ib puag ncig peb. Cov muaj pes tsawg leeg ntawm cov hlwb tuaj yeem pom nyob rau hauv ob hom: eukaryotic hlwb thiab prokaryotic hlwb. Thawj ntu ntawm cov npe "eu" thiab "pro" txhais tau tias zoo thiab ua ntej, feem. Lub sij hawm thib ob yog hais txog lub nucleus. Yog li, eukaryotic txhais tau hais tias zoo nucleus (muaj lub nucleus tseeb) thaum prokaryotic hais txog ua ntej lub nucleus.
Eukaryotic Cells yog dab tsi?
Eukaryotic hlwb muaj nyob rau hauv cov fungi, protists, nroj tsuag, thiab tsiaj txhu. Lawv yog cov hlwb uas muaj cov nucleus tseeb thiab cov kab mob sib txuas ua ke. Tsis tas li ntawd, cov plasma membrane npog cov cell, thiab lawv muaj 80S ribosomes. Cov hlwb no sib txawv heev ntawm cov hlwb prokaryotic. Ntxiv mus, ntau cov kab chromosomes muaj nyob rau hauv cov hlwb, thiab lawv nyob rau hauv lub nucleus.
Daim duab 01: Eukaryotic Cell
Cov qauv ntawm tes eukaryotic txawv ntawm cov nroj tsuag thiab tsiaj txhu. Lawv muaj cov txheej txheem photosynthesis thiab ua pa.
Cov Cells Prokaryotic yog dab tsi?
Prokaryotic hlwb tsis muaj cov nucleus hauv lawv. Lawv muaj nyob rau hauv ntau yam duab. Lawv muaj plaub hau zoo li cov qauv ntawm lawv qhov chaw. Piv txwv li, cov kab mob thiab archaea yog prokaryotes uas qhia txog lub koom haum prokaryotic cellular.
Daim duab 02: Prokaryotic Cell
Ntxiv mus, lawv paub tias muaj ib lub xov tooj ntawm tes. Tsis tas li ntawd, lawv nqa cytoplasm, plasma membrane, thiab ribosome nyob rau hauv lawv. Lawv tsis txhawb kev yug me nyuam; Lawv cov kev tsim khoom feem ntau yog los ntawm cov txheej txheem asexual xws li binary fission, budding thiab lwm yam. Ib lub cell prokaryotic muaj ib lub voj chromosome uas ntab hauv cytoplasm.
Dab tsi zoo sib xws ntawm Eukaryotic Cells thiab Prokaryotic Cells?
- Eukaryotic cells thiab prokaryotic cells muaj DNA.
- Ob leeg tuaj yeem tsim dua.
- Kuj, ob leeg yog lub hlwb.
- Thiab, ob leeg muaj ribosomes.
- Tsis tas li ntawd, lawv ob leeg tsim cov protein.
- Ntxiv mus, ob lub hlwb thauj cov molecules hla lub cell membrane.
- Cov hlwb no xav tau lub zog los ua cov txheej txheem metabolic.
Qhov txawv ntawm Eukaryotic Cells thiab Prokaryotic Cells yog dab tsi?
Eukaryotic hlwb muaj qhov tseeb nucleus thiab muaj tseeb membrane-bound organelles thaum lub hlwb prokaryotic tsis muaj tseeb nucleus thiab muaj tseeb membrane-bound organelles. Nws yog qhov sib txawv tseem ceeb ntawm cov hlwb eukaryotic thiab cov hlwb prokaryotic. Ntxiv mus, lwm qhov sib txawv tseem ceeb ntawm cov hlwb eukaryotic thiab cov hlwb prokaryotic yog cov eukaryotes muaj ntau lub cellular thaum prokaryotes yog ib leeg-celled. Tsis tas li ntawd, DNA nyob rau hauv eukaryotic hlwb nyob rau hauv lub nucleus thaum DNA nyob rau hauv prokaryotic hlwb nyob rau hauv lub cytoplasm. Yog li, qhov no kuj yog qhov sib txawv tseem ceeb ntawm cov hlwb eukaryotic thiab cov hlwb prokaryotic. Tsis tas li ntawd, eukaryotic cell muaj ntau cov kab chromosomes thaum lub cell prokaryotic muaj ib lub voj chromosome.
Ntxiv qhov sib txawv ntawm cov hlwb eukaryotic thiab cov hlwb prokaryotic yog tias cov hlwb eukaryotic yog qhov nyuaj dua thaum cov hlwb prokaryotic yooj yim. Tsis tas li ntawd, cov fungi, protists, tsiaj txhu, thiab cov nroj tsuag muaj eukaryotic hlwb thaum Bacteria thiab Archaea muaj cov hlwb prokaryotic. Eukaryotic hlwb muaj ib daim nyias nyias uas nyob ib puag ncig lub nucleus, tsis zoo li cov cell prokaryotic. Kuj tseem muaj qhov sib txawv ntawm cov hlwb eukaryotic thiab cov hlwb prokaryotic raws li lawv cov txheej txheem tsim tawm. Kev faib cell hauv eukaryotes tshwm sim los ntawm mitosis thiab meiosis thaum lub cell faib hauv prokaryotes tshwm sim los ntawm binary fission.
Summary – Eukaryotic Cells vs Prokaryotic Cells
Nws tau hais tias cov hlwb prokaryotic tau pom ntxov dua li cov hlwb eukaryotic. Eukaryotic hlwb muaj cov qauv sib txawv dua li yav tas los, raws li lawv nqa cov nucleus hauv lawv cov qauv. DNA ntawm eukaryotic hlwb yog nyob rau hauv lub nucleus, thiab nyob rau hauv prokaryotic nws mus dawb nyob rau hauv lub cytoplasm. Eukaryotic hlwb muaj cov qauv nyuaj heev, thiab lawv qhov ntau thiab tsawg yog kaum npaug loj dua qhov loj ntawm cov hlwb prokaryotic. Prokaryotic cell qauv yog qhov yooj yim heev thiab me me. Qhov no yog qhov sib txawv ntawm eukaryotic hlwb thiab prokaryotic hlwb.
