Qhov no Elodea nplooj cell piv txwv li ib tsob nroj cell . Nws muaj ib tug nucleus, thiab tawv cell phab ntsa uas muab cov cell nws lub thawv zoo li lub thawv. Ntau cov chloroplasts ntsuab tso cai rau cell ua nws cov zaub mov (los ntawm photosynthesis). Zoo li tsiaj hlwb , lub cytoplasm ntawm cov nroj tsuag no cell yog ciam teb los ntawm a cell daim nyias nyias.
Kuj nug, puas yog elodea prokaryotic lossis eukaryotic?
Ob leeg ntawm no yog cov piv txwv ntawm prokaryotes . Peb kuj yuav soj ntsuam ntau yam eukaryotic tshuaj cov hlwb, suav nrog cov piv txwv ntawm cov protists (Paramecia), cov hlwb cog ( Elodea thiab dos) thiab tsiaj hlwb (tib neeg epithelial hlwb). Feem ntau, eukaryotic tshuaj cov hlwb muaj ntau ntau thiab ntau dua prokaryotic hlwb.
Tsis tas li ntawd, muaj pes tsawg lub hlwb nyob hauv nplooj elodea? Feem ntau Elodea nplooj muaj 3 txheej hlwb.
Tom qab ntawd, elodea nplooj yog dab tsi?
Elodea yog ib qho underwater perennial cog nrog ntev trailing stems thiab ntsuab semi-translucent nplooj . Nws tuaj yeem tsim tawm, aggressively, los ntawm me me tawg tawg tawg. qia: ntev, slender, branched. Nplooj : Feem ntau teem nyob rau hauv whorls ntawm 3, yuav muaj anomalous whorls ntawm.
Dab tsi yog cov txheej txheem ntawm Cyclosis hauv elodea hlwb?
Hauv cyclosis ntawm dej cog nplooj, xws li elodea , cytoplasmic streaming tshwm sim hauv txhua qhov nyob cell ntawm cov nroj tsuag yam tsis muaj kev cuam tshuam los yog deformation ntawm cov hlwb ' membrane. Lub cytoskeleton contributes rau cov cell cov zoo, pab txav organelles nyob rau hauv lub cytoplasm.

Dab tsi yog qhov txawv ntawm tsiaj cell thiab cog cell?
Qhov sib txawv ntawm cov nroj tsuag thiab cov tsiaj hlwb yog tias cov tsiaj txhu feem ntau yog puag ncig thaum cov nroj tsuag feem ntau yog cov duab plaub. Cov nroj tsuag muaj cov phab ntsa tawv tawv uas nyob ib puag ncig cov cell membrane. Tsiaj cell tsis muaj phab ntsa ntawm tes
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
Lub ntsiab lus ntawm cog cell thiab tsiaj cell yog dab tsi?
Tsiaj Thiab Nroj Tsuag Cell. Txhua yam muaj sia nyob, nroj tsuag lossis tsiaj txhu yog tsim los ntawm cov hlwb. Lub cytoplasm nyob rau hauv ib lub cell muaj chloroplast thiab lwm yam plastids, mitochondria, dictyosomes, ribosomes, du thiab ntxhib endoplasmic reticulum, nucleus thiab lwm yam. Ib tug tsiaj cell yog ntau dua los yog tsawg spherical
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
