Kev kawm ntawm hlwb hu ua cell biology, cellular biology, los yog cytology. Cells muaj cytoplasm nyob rau hauv ib daim nyias nyias, uas muaj ntau yam biomolecules xws li cov proteins thiab nucleic acids. Feem ntau cov nroj tsuag thiab tsiaj txhu hlwb tsuas yog pom nyob rau hauv lub tshuab tsom, nrog qhov ntev ntawm 1 txog 100 micrometers.
Hais txog qhov no, cov cell ua los ntawm dab tsi?
A cell yog qhov pib ua los ntawm biological molecules (proteins, lipids, carbohydrates thiab nucleic acids). Cov biomolecules no yog tag nrho ua los ntawm Carbon, hydrogen thiab oxygen. Proteins thiab nucleic acids muaj Nitrogen.
Qhov thib ob, qhov sib txawv ntawm cov hlwb yog dab tsi? Muaj ntau pua hom hlwb, tab sis cov hauv qab no yog 11 feem ntau.
- Stem Cells. Pluripotent qia cell.
- Cov pob txha. Coloured scanning electron micrograph (SEM) ntawm khov-fractured osteocyte (ntsuab) ncig ntawm pob txha (grey).
- Cov Ntshav.
- Cov leeg nqaij.
- Fat Cells.
- Cov tawv nqaij.
- Nerve Cells.
- Endothelial Cells.
Tom qab ntawd, cov haujlwm ntawm cov hlwb yog dab tsi?
Cells muab rau lub ntsiab muaj nuj nqi . Lawv muab cov qauv thiab kev txhawb nqa, pab txhawb kev loj hlob los ntawm mitosis, tso cai rau kev thauj mus los tsis zoo thiab nquag, tsim lub zog, tsim cov tshuaj tiv thaiv metabolic thiab pab hauv kev yug me nyuam.
Cov kws tshawb fawb tshawb fawb li cas?
Cov txheej txheem kev yees duab nthuav cov organelles thiab taug qab hlwb thaum lawv faib, loj hlob, sib cuam tshuam, thiab ua lwm yam haujlwm tseem ceeb. Biochemical lossis genetic tests tso cai rau cov kws tshawb fawb kawm ua li cas hlwb teb rau ib puag ncig kev ntxhov siab, xws li nce kub lossis co toxins.

Dab tsi yog qhov txawv ntawm kev siv science thiab natural science?
Natural sciences cuam tshuam nrog lub ntiaj teb lub cev thiab suav nrog astronomy, biology, chemistry, geology, thiab physics. Applied science yog cov txheej txheem ntawm kev siv cov kev paub txog kev tshawb fawb rau cov teeb meem, thiab siv rau hauv kev lag luam xws li engineering, kev saib xyuas kev noj qab haus huv, kev siv technology, thiab kev kawm thaum yau
Kev sib raug zoo ntawm science thiab social science yog dab tsi?
Kev tshawb fawb (tseem hu ua ntshiab, ntuj, lossis kev tshawb fawb lub cev) thiab kev tshawb fawb txog kev sib raug zoo yog ob hom kev tshawb fawb uas cuam tshuam nrog tib cov qauv kev tshawb fawb thiab cov khoom ntawm lawv tus kheej txoj cai lij choj. Kev tshawb fawb muaj kev txhawj xeeb ntau dua nrog kev kawm xwm, thaum kev tshawb fawb txog tib neeg kev coj cwj pwm thiab kev sib raug zoo
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
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
