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.
