samiam99 Posted May 27, 2011 Share Posted May 27, 2011 State how many chromosomes and chromatid are found...is this correct? spermatogenesis --------------------------------------… Primordial germ cells- 2n =46 chromosomes and 46 chromatid..because chromosomes have not yet entered s phase? spermatogonial stem cells- still 46 chromatid and 46 chromosomes primary spermatocyte- s phase has occured so 46 chromosome and 92 chromatid? --------------------------------------… oogenesis primordial germ cell= 46 chromosomes 46 chromatid oogonia- s phase has not occured?- 46 chromosomes and 46 chromatid primary oocyte- s phase has occured so 46 chromatid and 92 chromatid? ootid and the polar bodies are each haploid with 23 chromosome and 23 chromatid? --------------------------------------… Lastly angiosperm - sporophyte...assuming they are 2N=46 sporangia is the chambers where gametophytes are produced one question said number of chromosomes in the sporangium cell found on anthers - so they are referring to microsporocytes?- 46 chromosomes 92 chromatid? magasporocyte and microsporocytes=diploid 46 and 92 chromatid endosperm = 3N triploid so 69 chromosome 69 chromatid? antipodal and tube cell= 23 chromosomes and 23 chromatid flower petal and parencyma cell of the leaf- I'm assuming these are like nervous system or brain cells and are arrested in G phase so 46 chromosome and 46 chromatid?

jimmydasaint Posted May 29, 2011 Share Posted May 29, 2011 This may help you. Just follow the chromosomes and chromatids from the mother cell: Cells Alive Link to comment Share on other sites More sharing options...
