Kev faib tawm ntawm tes yog txheej txheem uas a ntawm tes , hu ua niam txiv ntawm tes , faib ua ob hlwb , hu ua tus ntxhais hlwb . Hauv mitosis, lub cev zoo tib yam (somatic) ntawm tes faib ua ob tug ntxhais hlwb . Hauv meiosis, a ntawm tes faib ob zaug, los tsim plaub gametes (kev sib deev hlwb ).
Ntxiv mus, dab tsi yog cov txheej txheem ntawm kev faib cell hu ua?
mitosis / cov cell faib . Mitosis yog ib txheej txheem ntawm nuclear faib hauv eukaryotic hlwb uas tshwm sim thaum niam txiv ntawm tes faib ua ob tug ntxhais zoo tib yam hlwb . Lub sijhawm cell faib , mitosis hais tshwj xeeb rau kev sib cais ntawm cov khoom siv caj ces duplicated nqa hauv lub nucleus.
Tsis tas li ntawd, 3 hom kev faib cell yog dab tsi? Xovtooj yuav tsum sib faib thiaj li tsim tau ntau hlwb . Lawv ua tiav qhov no faib nyob rau hauv peb txawv txoj kev hu ua mitosis, meiosis, thiab binary fission. Mitosis yog tus txheej txheem ntawm koj lub cev hlwb siv txhawm rau tsim cov ntawv theej ntawm lawv tus kheej, hu ua ntxhais hlwb.
Ua kom pom qhov no, txhais li cas los ntawm kev faib cell?
Kev faib tawm ntawm tes yog txheej txheem uas niam txiv ntawm tes faib ua ob tug los sis ntau tus ntxhais hlwb . Kev faib tawm ntawm tes feem ntau tshwm sim ua ib feem ntawm qhov loj dua cell voj voog . Prokaryotes (cov kab mob) yauv tsum muaj zaub cell faib hu ua binary fission, qhov twg lawv cov khoom siv caj ces raug cais sib npaug rau ob tug ntxhais hlwb.
Dab tsi yog hom kev faib cell loj?
Muaj peb leeg hom tseem ceeb ntawm kev faib cell : binary fission, mitosis, thiab meiosis. Binary fission yog siv los ntawm cov kab mob yooj yim xws li cov kab mob. Ntau yam kab mob tau txais tshiab hlwb los ntawm mitosis lossis meiosis.

Dab tsi yog qhov sib txawv ntawm squamous yooj yim thiab yooj yim cuboidal thiab columnar yooj yim?
Piv txwv li, yooj yim squamous epithelial cov ntaub so ntswg piav qhia ib txheej ntawm cov cell uas tiaj thiab nplai zoo li cov duab. Cuboidal epithelium muaj cov cell uas nws qhov siab thiab dav yog kwv yees tib yam. Columnar epithelium muaj cov cell siab dua li lawv dav
Cov txheej txheem yooj yim ntawm kev ua pa ntawm tes yog dab tsi?
Kev ua pa ntawm tes tau noj zaub mov thiab siv nws los tsim ATP, cov tshuaj uas lub cell siv rau lub zog. Feem ntau, cov txheej txheem no siv oxygen, thiab hu ua aerobic respiration. Nws muaj plaub theem hu ua glycolysis, Txuas cov tshuaj tiv thaiv, lub voj voog Krebs, thiab cov thauj khoom hluav taws xob
Dab tsi yog txheej txheem uas cov cell yooj yim dhau los ua cov cell tshwj xeeb?
Cell sib txawv yog li cas generic embryonic hlwb ua cov hlwb tshwj xeeb. Qhov no tshwm sim los ntawm cov txheej txheem hu ua noob qhia. Kev qhia cov noob yog kev sib xyaw tshwj xeeb ntawm cov noob uas tau qhib lossis tawm (qhia lossis thawb), thiab qhov no yog qhov qhia tias lub xov tooj ntawm tes ua haujlwm li cas
Cov kauj ruam hauv cov txheej txheem txheej txheem txheej txheem mob yog dab tsi?
Cov ntsiab lus hauv cov txheej txheem no (8) ua kom cov vascular endothelium. vasodilation. ua npaws ntau lawm. tsiv teb tsaws ntawm cov kab mob tiv thaiv kab mob hlwb mus rau thaj chaw. ua kom thiab cytokine tso tawm los ntawm neutrophils. phagocytosis thiab cov hau kev ntawm kev puas tsuaj. tus mob theem teb. clotting cascade
Qhov twg ntawm cov txheej txheej txheej hauv qab no ua haujlwm hauv kev faib cell?
19 Daim Npav nyob rau hauv Txheej Txheej txheej ntawm cov epidermis uas muaj qhov sib faib cell ceev tshaj plaws. Stratum basale Epidermal txheej uas muaj cov qia hlwb Stratum basale Dermal txheej nrog cov hauv paus plaub hau thiab qog Superficial dermis Tiv thaiv daim tawv nqaij tiv thaiv kab mob kab mob Langerhans hlwb tsim keratin. Keratinocytes
