Txhua lub cell muaj plasma membrane, cov ribosomes , cytoplasm , thiab DNA.
Prokaryotic Cells.
| Prokaryotic Cells | Eukaryotic Cells | |
|---|---|---|
| Nucleus | Tsis muaj | Yog lawm |
| DNA | Ib ncig daim ntawm DNA | Ntau chromosomes |
| Membrane-Bound Organelles | Tsis muaj | Yog lawm |
| Piv txwv | Kab mob | Nroj tsuag, tsiaj txhu, fungi |
Kuj tseem paub yog, puas yog DNA hauv cytoplasm thiab ntawm ribosome?
Cov mRNA molecules raug thauj los ntawm lub hnab ntawv nuclear rau hauv cytoplasm , qhov twg lawv raug txhais los ntawm rRNA ntawm cov ribosomes (saib kev txhais lus). protein synthesis DNA hauv cell nucleus nqa ib txoj cai caj ces, uas muaj cov kab ke ntawm adenine (A), thymine (T), guanine (G), thiab cytosine (C) (Daim duab 1).
Ib yam li ntawd, puas yog txhua lub hlwb puas muaj ribosomes hauv cytoplasm? Thaum ib tug qauv xws li a nucleus yog tsuas yog pom hauv eukaryotes, txhua cell xav tau cov ribosomes los tsim cov protein. Txij thaum ntawd los yog tsis muaj daim nyias nyias-khi organelles hauv prokaryotes, lub cov ribosomes ntab dawb nyob rau hauv cytosol . Ribosomes yog pom nyob rau hauv ntau qhov chaw nyob ib ncig ntawm ib tug eukaryotic cell.
Tsis tas li ntawd, txhua lub hlwb puas muaj DNA thiab ribosomes?
Txhua lub hlwb muaj plasma membrane, cov ribosomes , cytoplasm, thiab DNA.
Dab tsi tuaj yeem ribosomes piv rau?
Kuv piv tus cov ribosomes nyob rau hauv ib lub cell mus rau chav ua noj nyob rau hauv ib lub tsev. Cov cov ribosomes zoo li chav ua noj hauv tsev vim chav ua noj ua zaub mov, zoo li lub cov ribosomes tsim cov proteins hauv cell.

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
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 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
Tsis muaj dab tsi tab sis lub ntuj xiav txhais li cas?
Kom tsis muaj dab tsi ua rau qhov kev ua txhaum cai no. 3 qhov teeb meem tsis muaj qhov tseem ceeb lossis qhov tseem ceeb. tsis muaj teeb meem, tsis muaj dab tsi. 4 qhia tias tsis muaj dab tsi pom tau; tsis muaj dab tsi. 5 qhia qhov tsis muaj lub ntsiab lus, tus nqi, tus nqi, thiab lwm yam
