meiosis ib txwm tshwm sim hauv cov kabmob.
Puas meiosis tshwm sim hauv Megasporogenesis?
Megasporogenesis yog hais txog kev loj hlob ntawm megaspores los ntawm megasporocyte, lub cell uas nkag mus meiosis. Meiosis ntawm megasporocyte nucleus tshwm sim hauv kev tsim ntawm plaub haploid megaspore nuclei.
Megasporogenesis Nws nyob qhov twg?
Megasporogenesis yog txheej txheem ntawm kev npaj megaspores los ntawm megaspore niam cell. Nws tshwm sim inside the pollen sac of the anther.
