A zygote ua yog eukaryotic cell tsim vim fertilization tshwm sim ntawm ob gametes. Nws pib faib ua ob hlwb , tiam 4 hlwb , yim hlwb , 16 hlwb , thiab lwm yam. Nws yog qhov no tsis tu ncua cell faib uas tso cai rau tus singled cell zygote los tsim ib tug neeg multicellular.
Tom qab ntawd, ib tug kuj yuav nug, pes tsawg lub hlwb puas muaj zygote?
Nyob rau hauv tib neeg fertilization, lub qe tso tawm (ib tug haploid theem nrab oocyte nrog replicate chromosome luam) thiab cov phev haploid cell (txiv neej gamete)-ua ke los tsim ib qho 2n diploid cell hu ua zygote ua.
Ib tug kuj yuav nug, yog zygote theem unicellular los yog multicellular? 1. Zygote hauv unicellular hos embryo yog multicellular . 2. Zygote yog hu ua zygocyte hauv cov lus kho mob thaum lub embryo yog hu ua diploid eukaryote.
Ib yam li ntawd, tib neeg nug, yog zygote ib leeg xwb?
Zygote . Cov zygote ua , los yog fertilized qe, yog a ib leeg tsim los ntawm fusion ntawm poj niam thiab txiv neej kab mob hlwb , uas yog, lub qe unfertilized thiab phev, feem.
Puas yog zygote yog lub cev?
Cov zygote ua / embryo yog tag nrho cov tib neeg sib txawv kab mob -uas yog, tib neeg, ib tus tswv cuab ntawm tus kheej tsim ntawm homo sapiens-nyob rau theem pib ntawm lub neej. Lwm cov cell tsuas yog ib feem ntawm cov loj loj, tsis yog tus kheej kab mob lawv tus kheej. Tab sis lub sij hawm " kab mob "yuav tsum tau piav qhia.
