Txhais. Ib archesporial xov tooj uas yog ib feem ntawm megasporangium thiab faib ua kom nce mus rau megasporocyte. Foundin heterosporous ferns thiab noob nroj tsuag. Tej zaum kuj ua rau kom tosterile hlwb.
Tsis tas li ntawd, lub ntsiab lus ntawm Archesporial yog dab tsi?
archesporial - Kev txhais lus txhais thiab lub ntsiab lus rau lus archesporial . (adj) ntawm lossis cuam tshuam nrog cov cell hauv sporangium uas ua rau kom muaj kab mob.
Ib tug kuj yuav nug, qhov ua haujlwm ntawm Microsporangium yog dab tsi? muaj nuj nqi hauv kev cog qoob loo Microsporangia (txiv neej sporangia) tsim cov microsporocytes (micromeiocytes) uas tawm los microspores. Megasporangia (poj niam sporangia) tsim megasporocytes (megameiocytes) uas tawm los megaspores.
Hauv qhov no, Sporogenous cell yog dab tsi?
Cov txheej txheem cuam tshuam nrog sporogenous hlwb (sporocytes, tseem hu ua niam niam hlwb ) ua ntej ntawm tes kev faib ua kom nce mus rau spores. Nyob rau hauv meioticsporogenesis, ib tug diploid spore niam ntawm tes hauv sporangium hla meiosis, tsim tetrad ntawm haploidspores.
Hypodermal cell yog dab tsi?
ib tug underlayer ntawm epithelial hlwb nyob rau hauv arthropods thiab lwm yam invertebrates uas secretes tshuaj rau theoverlying cuticle los yog exoskeleton. ib daim ntaub los yog txheej ntawm hlwb hauv qab lub epidermis.

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
Dab tsi yog cov txheej txheem uas tsim ntau cov cell los ntawm ib lub cell?
Lub cell tau txais ib hom kev faib cell hu ua mitosis. Hauv mitosis, ob lub hlwb hu ua tus ntxhais cell raug tsim, txhua qhov zoo ib yam rau niam txiv cell
Dab tsi yog txheej txheem uas lub cell faib ua ob lub cell ntxhais?
Mitosis yog txheej txheem tseem ceeb rau lub neej. Thaum lub sij hawm mitosis, lub xov tooj ntawm tes duplicates tag nrho nws cov ntsiab lus, suav nrog nws cov chromosomes, thiab sib cais los ua ob lub hlwb zoo tib yam. Vim tias cov txheej txheem no tseem ceeb heev, cov theem ntawm mitosis tau ua tib zoo tswj hwm los ntawm cov noob
ICD 10 tus lej yog dab tsi rau keeb kwm ntawm cell cell carcinoma?
Tus kheej keeb kwm ntawm lwm cov qog nqaij hlav malignant ntawm daim tawv nqaij Z85. 828 yog ib daim ntawv them nqi / tshwj xeeb ICD-10-CM code uas tuaj yeem siv los qhia txog kev kuaj mob rau kev them nyiaj rov qab. 2020 tsab ntawm ICD-10-CM Z85. 828 tau pib ua haujlwm thaum Lub Kaum Hli 1, 2019
Qhov txawv ntawm B cell thiab T cell lymphomas yog dab tsi?
Thaum B cov cell tsim cov tshuaj tiv thaiv kab mob uas tsom mus rau cov kab mob, T cells ncaj qha tua cov kab mob lossis cov kab mob uas muaj kab mob. Hom lymphoma no yog ib hom kab mob loj hlob sai uas kho tau zoo li mob leukemia
