Eukaryotic hlwb yog hlwb uas muaj ib tug nucleus thiab organelles, thiab nyob rau hauv lub plasma membrane. Cov kab mob no tau muab faib ua pawg lom sau npe Eukaryota. Eukaryotic hlwb yog loj thiab complex tshaj prokaryotic hlwb , uas muaj nyob rau hauv Archaea thiab Bacteria, lwm yam ob hom ntawm lub neej.
Yog li, eukaryote hauv biology yog dab tsi?
A eukaryotes yog ib yam kab mob uas nws cov hlwb muaj cov nucleus nyob rau hauv ib daim nyias nyias. Qhov tseeb, feem ntau muaj sia nyob eukaryotes , ua los ntawm cov hlwb nrog cov nuclei thiab chromosomes uas muaj lawv cov DNA. Cov kab mob tib yam uas tsis yog eukaryotes yog cov kab mob thiab archaea, hu ua prokaryotes.
Ib sab saum toj no, eukaryotic cell thiab prokaryotic cell yog dab tsi? Koj hlwb yog eukaryotic tshuaj . Eukaryotic hlwb muaj cov organelles membrane-bound, nrog rau cov nucleus. Eukaryotes tuaj yeem ua ib leeg lossis ntau lub cell, xws li koj, kuv, nroj tsuag, fungi, thiab kab. Cov kab mob yog ib qho piv txwv ntawm prokaryotes . Prokaryotic hlwb tsis muaj cov nucleus los yog lwm yam membrane-bound organelle.
Tsuas yog li ntawd, dab tsi yog qhov zoo tshaj plaws txhais ntawm eukaryotic cell?
Eukaryotic hlwb yog cov hlwb uas posses ib daim nyias nyias bound nucleus thiab lwm yam organelles kuj membrane khi. Lawv nthuav tawm ib lub qhov dej txhais nucleus uas muaj cov khoom siv caj ces hauv daim ntawv ntawm DNA. Cov kab mob uas nthuav tawm eukaryotic hlwb yog protozoa, nroj tsuag thiab tsiaj txhu.
4 piv txwv ntawm eukaryotic hlwb yog dab tsi?
Piv txwv ntawm Eukaryotic Cells:
- Tsiaj txhu xws li miv thiab dev muaj eukaryotic hlwb.
- Cov nroj tsuag xws li txiv apples muaj eukaryotic hlwb.
- Fungi xws li nceb muaj eukaryotic hlwb.
- Protists xws li amoeba thiab paramecium muaj eukaryotic hlwb.
- Kab muaj eukaryotic hlwb.
Pom zoo:
Dab tsi yog pom hauv eukaryotic hlwb tab sis tsis yog cov hlwb prokaryotic?
Eukaryotic hlwb muaj cov kab mob sib txuas ua ke, xws li cov nucleus, thaum cov hlwb prokaryotic tsis ua. Qhov sib txawv hauv cellular qauv ntawm prokaryotes thiab eukaryotes muaj xws li muaj mitochondria thiab chloroplasts, phab ntsa cell, thiab cov qauv ntawm chromosomal DNA
Qhov txawv ntawm prokaryotic thiab eukaryotic cell division yog dab tsi?
Cell faib yog yooj yim dua nyob rau hauv prokaryotes tshaj eukaryotes vim hais tias prokaryotic hlwb lawv tus kheej yog yooj yim. Cov hlwb prokaryotic muaj tib lub voj voog chromosome, tsis muaj nucleus, thiab ob peb lwm cov qauv ntawm tes. Eukaryotic hlwb, nyob rau hauv sib piv, muaj ntau yam chromosomes nyob rau hauv ib tug nucleus, thiab ntau lwm yam organelles
Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Dab tsi yog 2 qhov tseem ceeb ntawm lub voj voog ntawm tes thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Cov xwm txheej no tuaj yeem muab faib ua ob qhov tseem ceeb: interphase (hauv nruab nrab ntawm kev sib faib theem ua pawg G1 theem, S theem, G2 theem), thaum lub xov tooj ntawm tes tsim thiab ua nrog nws cov haujlwm metabolic; mitotic theem (M mitosis), thaum lub sij hawm lub cell yog replicating nws tus kheej
Dab tsi yog cell membrane hauv prokaryotic cell?
Prokaryotes thiab eukaryotes yog ob hom cell uas muaj nyob. Tab sis, prokaryotes muaj qee cov organelles nrog rau cov cell membrane, kuj hu ua phospholipid bilayer. Cov cell membrane no kaw lub cell thiab tiv thaiv nws, tso cai rau hauv qee cov molecules raws li qhov xav tau ntawm tes
