Teb tiav: Kev faib ntawm lub xov tooj ntawm tes yuav tshwm sim los ntawm mitosis thiab tom qab mitosis cytokinesis tsis tshwm simthiab hom mitosis no hu ua endomitosis thiab nws ua rau binucleate. los yog multinucleate tapetum.
Vim li cas cov hlwb ntawm tapetum yog binucleate?
Lawv pab cov paj ntoos paj ntoos loj hlob thiab loj hlob. Tapetal cells undergo endomitosis qhov twg cov nucleus nyob rau hauv daim nyias nyias nyias faib, tab sis cytokinesis tsis tshwm sim. Yog li ntawd lawv yog bi/poly nucleate.
Ploidy ntawm Tapetal cells yog dab tsi?
Nws yog diploid Tapetum yog nyob rau hauv anther uas txhawb rau kev nce qib ntawm hmoov av. nws yog diploid. … Nco qab tias nyob rau hauv cov nroj tsuag txhua lub hlwb yog diploid ib sab ntawm plua plav nplej thiab poj niam gametophyte (incipient organism sac) uas yog haploid, thiab tom qab kho endosperm yog zoo li tus uas yog triploid.
Puas Tapetal cells haploid?
Yog li, cov lus teb raug yog ' Polyploidy'.
Vim li cas tapetum cells muaj ntau dua ib lub nucleus?
Nws muab kev noj qab haus huv rau cov microspores loj hlob (pollen nplej). Cells ntawm tapetum muaj ntom cytoplasm thiab ntau dua ib lub nucleus. Lub binucleate (nrog ob lub nucleus) los yog multinucleate (ntau tshaj ob lub nucleus) mob tshwm sim vim fusion ntawm ob uninucleate (ib tug nucleus) hlwb ntawm tapetum.
