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.
