This question asks, with respect to angiosperms, which of the following is incorrectly paired with its chromosome count? we have egg, which is n, megaspore, which is 2n, microspor which is n, and zygote, which is 2n.
00:16
So we know that zygote are going to be 2n, or diploid, because they are going to be the combination of an egg and a sperm cell, meaning that we have combined two haploid cells together to form our diploid zygote.
00:32
So our zygote will be correct in saying that it is diploid.
00:39
And if we are to look at our egg, we know that it is haploid, or it is correct in saying that it is haploid, because it will have to be haploid in order for our sperm cell to join with it, which is also haploid, to produce our diploid zygote.
00:56
And then we just have to differentiate between our megaspore and the microspore.
01:00
So we know that the megaspore right here is going to be our female gamete in these angiosperm plants.
01:13
And as you can see, some of these megaspore nuclei eventually become the egg and also polar nuclei and these antipotals and synergies.
01:26
But if we just focus on it, we know that one of these megaspore nuclei eventually becomes the egg.
01:32
And it still remains as a haploid cell throughout its mitotic divisions, right after it undergoes meiosis from a megasporocyte cell...
