Nyob hauv cov nroj tsuag, spores yog feem ntau haploid thiab unicellularthiab yog tsim los ntawm meiosis hauv sporangium ntawm diploid sporophyte. Nyob rau hauv cov xwm txheej zoo, cov spores tuaj yeem txhim kho mus rau hauv cov kab mob tshiab uas siv mitotic division, tsim cov multicellular gametophyte, uas nws thiaj li mus ua gametes.
Puas yog tsob nroj spores haploid lossis diploid?
Gametes yeej ib txwm haploid, thiab spores feem ntau yog haploid (spores ib txwm haploid hauv cov nroj tsuag hloov pauv ntawm ntau tiam neeg lub neej voj voog). Nyob rau hauv kev hloov ntawm ntau tiam neeg lub neej voj voog, piv txwv li hauv qab no, muaj ib tug paub tab multicellular haploid theem thiab mature multicellular diploid theem.
Puas yog cov kab mob diploid cell?
Diploid sporophyte hlwb raug meiosis los tsim cov spores haploid. Txhua spores mus los ntawm kev sib faib mitotic kom tau txais ntau lub cellular, haploid gametophyte. Mitotic faib nyob rau hauv gametophyte yuav tsum tau tsim cov gametes.
Puas yog moss spores haploid lossis diploid?
Mosses muaj diploid thiab haploid tiam. Gametophytes, spores, phev, thiab qe yog tag nrho cov haploid. Zygotes thiab lawv cov txiaj ntsig sporophytes yog diploid. Mosses tuaj yeem tsim kev sib deev lossis sib deev.
Puas yog spores haploid lossis diploid quizlet?
Ob leeg spores thiab gametes yog unicellular thiab haploid. Gametes yog luv luv thiab xav tau dej; lawv muaj peev xwm sib txuas nrog lwm tus gamete.
