Mitosis yog tus txheej txheem uas lub nucleus ntawm ib tug eukaryotic cell faib. Thaum tus txheej txheem no, tus muam chromatids cais los ntawm txhua lwm yam thiab txav mus rau opposite ncej ntawm lub cell. Qhov no tshwm sim hauv plaub theem , hu ua prophase, metaphase, anaphase, thiab telophase.
Yog li, theem twg tshwm sim tom qab mitosis?
Cytokinesis yog kev faib ntawm cov cell cytoplasm. Nws pib ua ntej kawg ntawm mob mitosis hauv anaphase thiab ua tiav sai tom qab telophase / mob mitosis . Thaum kawg ntawm cytokinesis, ob lub noob caj noob ces zoo tib yam yog tsim. Cov no yog cov hlwb diploid, nrog rau txhua lub cell muaj tag nrho cov chromosomes.
Tsis tas li ntawd, lub hom phiaj ntawm txhua theem ntawm mitosis yog dab tsi? Mitosis yog ib txoj kev uas ib lub xovtooj sib faib ua ob lub hlwb zoo tib yam (cell division). Thaum mob mitosis ib cell? faib ib zaug los tsim ob lub hlwb zoo ib yam. Qhov loj lub hom phiaj ntawm mob mitosis yog rau kev loj hlob thiab hloov pauv cov cell uas ploj lawm.
Yog li, dab tsi tshwm sim hauv txhua theem ntawm meiosis?
Cov theem ntawm meiosis Muaj ntau txoj hauv kev, meiosis Nws zoo li mitosis. Txij li kev faib cell tshwm sim ob zaug thaum meiosis , ib lub cell pib tsim tau plaub gametes (qe lossis phev). Hauv txhua puag ncig ntawm kev faib, hlwb mus txog plaub theem : prophase, metaphase, anaphase, thiab telophase.
Tus txheej txheem ntawm meiosis yog dab tsi?
Meiosis yog a txheej txheem qhov twg ib lub cell faib ob zaug los tsim plaub lub hlwb uas muaj ib nrab ntawm cov ntaub ntawv keeb kwm yav dhau los. Cov hlwb no yog peb cov poj niam cev xeeb tub - phev hauv txiv neej, qe hauv poj niam.

Ob theem tseem ceeb ntawm photosynthesis yog dab tsi thiab txhua theem tshwm sim nyob qhov twg?
Ob theem ntawm photosynthesis: Photosynthesis yuav siv sij hawm qhov chaw nyob rau hauv ob theem: lub teeb-dependent kev tshwm sim thiab lub Calvin voj voog (lub teeb-yooj yim kev xav). Lub teeb-nyob ntawm cov tshuaj tiv thaiv, uas tshwm sim hauv thylakoid daim nyias nyias, siv lub teeb lub zog los ua ATP thiab NADPH
Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Cov kauj ruam ntawm mitosis yog dab tsi thiab dab tsi tshwm sim hauv txhua qhov?
Mitosis muaj tsib theem sib txawv: interphase, prophase, metaphase, anaphase thiab telophase. Cov txheej txheem ntawm cell faib tsuas yog ua tiav tom qab cytokinesis, uas tshwm sim thaum lub sij hawm anaphase thiab telophase. Txhua theem ntawm mitosis yog tsim nyog rau cell replication thiab faib
Dab tsi yog 2 qhov tseem ceeb ntawm lub voj voog ntawm tes thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Cov xwm txheej no tuaj yeem muab faib ua ob qhov tseem ceeb: interphase (hauv nruab nrab ntawm kev sib faib theem ua pawg G1 theem, S theem, G2 theem), thaum lub xov tooj ntawm tes tsim thiab ua nrog nws cov haujlwm metabolic; mitotic theem (M mitosis), thaum lub sij hawm lub cell yog replicating nws tus kheej
Yuav ua li cas tshwm sim nyob rau hauv txhua ntawm 4 theem ntawm mitosis?
Mitosis yog cov txheej txheem uas cov nucleus ntawm eukaryotic cell faib. Thaum lub sijhawm txheej txheem no, tus muam chromatids cais tawm ntawm ib leeg thiab txav mus rau cov ncej ntawm tes. Qhov no tshwm sim nyob rau hauv plaub theem, hu ua prophase, metaphase, anaphase, thiab telophase
