Cell membrane - qhov no puag ncig lub cell thiab tso cai rau cov as-ham nkag mus thiab pov tseg kom tawm mus. Nucleus - qhov no tswj qhov tshwm sim hauv lub cell . Nws muaj DNA, cov ntaub ntawv ntawm caj ces hlwb yuav tsum loj hlob thiab yug me nyuam. Cytoplasm - qhov no yog ib yam khoom zoo li jelly nyob rau hauv cov tshuaj tiv thaiv tshwm sim.
Ntawm no, cell ks3 yog dab tsi?
Kev piav qhia. Txhua yam tsiaj thiab nroj tsuag yog tsim los ntawm hlwb . Cheebtsam ntawm a cell thiab lawv cov haujlwm tau piav qhia: daim nyias nyias, cytoplasm, nucleus. Ntxiv rau cov no, cog hlwb kuj muaj a cell phab ntsa, vacuole thiab feem ntau chloroplasts.
Kuj Paub, dab tsi yog lub luag haujlwm ntawm tus tsiaj cell? Tsiaj Cells Function Cells nqa tawm tag nrho cov txheej txheem ntawm lub cev nrog rau tsim thiab khaws cia lub zog, ua cov proteins, rov ua dua DNA, thiab kev thauj mus los ntawm cov molecules los ntawm lub cev. Cells tshwj xeeb heev los ua cov haujlwm tshwj xeeb.
Tsis tas li ntawd, cov cell zoo li cas thiab lawv ua dab tsi?
Cells yog lub hauv paus tsev thaiv ntawm txhua yam muaj sia. Tib neeg lub cev yog tsim los ntawm trillions ntawm hlwb . Lawv muab cov qauv rau lub cev, nqa cov as-ham los ntawm cov zaub mov, hloov cov as-ham rau hauv lub zog, thiab ua haujlwm tshwj xeeb.
Lub cell ua los ntawm dab tsi?
A cell yog qhov pib ua Cov tshuaj lom neeg muaj pes tsawg leeg (cov protein, lipids, carbohydrates thiab nucleic acids). Cov biomolecules no yog tag nrho ua los ntawm carbon, hydrogen thiab oxygen. Proteins thiab nucleic acids muaj Nitrogen.

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Lub organelle twg yog lub luag haujlwm rau lub zog tshuaj uas xav tau rau lub cell ua haujlwm?
Mitochondria Function Mitochondria feem ntau hu ua "powerhouses" lossis "zog factories" ntawm lub xovtooj vim tias lawv yog lub luag haujlwm rau kev ua adenosine triphosphate (ATP), lub xovtooj ntawm lub zog nqa lub cev
Dab tsi organelle yog lub luag haujlwm rau kev thauj khoom hauv thiab tawm ntawm lub cell?
Function Of Cell Organelles A B cell membrane tswj kev txav mus rau hauv thiab tawm ntawm lub cell cytoplasm watery khoom uas muaj ntau cov ntaub ntawv koom nrog hauv cell metabolism endoplasmic reticulum ua txoj hauv kev rau kev thauj khoom thoob plaws hauv lub cell
Lub luag haujlwm ntawm lub cell membrane yog dab tsi thaum lub sijhawm thauj mus los?
Lub cell membrane yog xaiv permeable rau ions thiab organic molecules thiab tswj kev txav ntawm cov khoom hauv thiab tawm ntawm lub hlwb. Lub luag haujlwm tseem ceeb ntawm cov cell membrane yog los tiv thaiv lub cell ntawm nws ib puag ncig. Nws muaj phospholipid bilayer nrog embedded proteins
Cov txheej txheem dab tsi yog lub luag haujlwm rau txoj haujlwm ua haujlwm sib txawv?
Position-effect variegation (PEV) tshwm sim thaum cov noob ib txwm nyob hauv euchromatin yog sib xyaw nrog heterochromatin los ntawm kev hloov kho lossis hloov pauv. Thaum lub ntim ntim heterochromatin kis thoob plaws heterochromatin / euchromatin ciam teb, nws ua rau kev hloov pauv ntawm kev ntsiag to hauv tus qauv stochastic
