Video: Dab tsi yog pom hauv eukaryotic hlwb tab sis tsis yog cov hlwb prokaryotic?

Eukaryotic hlwb muaj cov membrane-bound organelles, xws li cov nucleus, thaum prokaryotic hlwb ua tsis yog . Qhov txawv hauv cellular qauv ntawm prokaryotes thiab eukaryotes suav nrog muaj mitochondria thiab chloroplasts, cov cell phab ntsa, thiab tus qauv ntawm chromosomal DNA.
Yog li ntawd, dab tsi yog qhov txawv ntawm prokaryotic thiab eukaryotic hlwb?
Prokaryotes yog cov kab mob uas ua los ntawm hlwb uas tsis muaj a cell nucleus los yog ib qho membrane-encased organelles. Eukaryotes yog cov kab mob uas ua los ntawm hlwb uas muaj ib daim nyias nyias ntawm cov nucleus uas tuav cov khoom siv caj ces nrog rau cov kab mob sib txuas nrog cov organelles.
Tsis tas li ntawd, prokaryotes thiab eukaryotes muaj dab tsi? Prokaryotic hlwb ua tsis yog muaj ib nucle. Ob leeg prokaryotic thiab eukaryotic hlwb muaj cov qauv hauv feem ntau . Txhua lub hlwb muaj plasma membrane, ribosomes, cytoplasm, thiab DNA. Lub plasma membrane, lossis cell membrane, yog txheej phospholipid uas nyob ib puag ncig ntawm tes thiab tiv thaiv nws los ntawm ib puag ncig sab nraud.
Tsuas yog li ntawd, 4 qhov zoo sib xws ntawm cov hlwb prokaryotic thiab eukaryotic yog dab tsi?
Zoo li ib prokaryotic cell , a eukaryotic cell muaj plasma membrane, cytoplasm, thiab ribosomes, tab sis a eukaryotic cell feem ntau yog loj dua ib prokaryotic cell , muaj ib qho tseeb nucleus (txhais tau tias nws cov DNA yog nyob ib puag ncig los ntawm daim nyias nyias), thiab muaj lwm cov kab mob sib txuas uas tso cai rau rau compartmentalization ntawm functions.
Dab tsi yog 2 piv txwv ntawm cov hlwb prokaryotic?
Piv txwv ntawm Prokaryotes:
- Cov kab mob Escherichia Coli (E. coli)
- Streptococcus kab mob. Qhov no prokaryote yog lub luag haujlwm rau strep caj pas.
- Streptomyces Av kab mob. Ntau tshaj 500 hom kab mob no tau piav qhia.
- Archaea. Cov subclass ntawm archaea yog prokaryotes thiab muaj peev xwm ciaj sia nyob rau hauv ib puag ncig hnyav heev.

Dab tsi yog cov tebchaw tab sis tsis yog molecules?
Txhua qhov sib xyaw ntawm atoms yog ib qho molecule. Ib qho kev sib txuas yog ib qho molecule ua los ntawm atoms los ntawm cov khoom sib txawv. Tag nrho cov tebchaw yog molecules, tab sis tsis yog tag nrho cov molecules yog cov tebchaw. Hydrogen gas (H2) yog ib qho molecule, tab sis tsis yog ib qho kev sib xyaw vim nws tsuas yog ua los ntawm ib lub ntsiab lus xwb
Dab tsi yog qhov txawv ntawm prokaryotic thiab eukaryotic hlwb hlwb?
Eukaryotic hlwb muaj cov kab mob sib txuas ua ke, nrog rau cov nucleus. Eukaryotes tuaj yeem ua ib leeg lossis ntau lub hlwb, xws li koj, kuv, nroj tsuag, fungi, thiab kab. Cov hlwb prokaryotic tsis muaj cov nucleus lossis lwm cov kab mob sib txuas ua ke
Dab tsi ntawm cov hauv qab no muaj nyob rau hauv cov tsiaj hlwb tab sis tsis yog cov nroj tsuag?
Mitochondria, Cell Phab ntsa, Cell membrane, Chloroplast, Cytoplasm, Vacuole. Lub cell phab ntsa, chloroplasts thiab vacuole muaj nyob rau hauv cov nroj tsuag cell es tsis yog tsiaj hlwb
Dab tsi yog lub npe rau cov khoom uas yaj hauv dej tab sis tsis tsim ions lossis ua hluav taws xob tam sim no?
Ib qho electrolyte yog ib yam khoom uas tsim cov kua hluav taws xob thaum yaj hauv cov kuab tshuaj polar, xws li dej. Cov yaj electrolyte cais mus rau hauv cations thiab anions, uas disperse uniformly los ntawm cov kuab tshuaj. Hluav taws xob, xws li kev daws teeb meem yog nruab nrab
Cov qauv twg feem ntau yuav pom tau nrog lub tshuab ntsuas hluav taws xob tab sis tsis yog lub teeb tsom iav?
Hauv qab ntawm cov qauv tsim yog pom nyob rau hauv tib lub cell, nyob rau sab laug saib nrog lub teeb microscope, thiab nyob rau sab xis nrog cov kis tau tus mob electron microscope. Mitochondria pom tau nrog lub teeb pom kev zoo tab sis tsis tuaj yeem pom meej. Ribosomes tsuas yog pom nrog lub tshuab ntsuas hluav taws xob
