Question

If an endosperm of an angiosperm has 24 chromosomes, what would be the number of chromosomes in the megaspore mother cell of the same plant

Answer 1

This makes endosperm triploid being the product of triple fusion between the diploid secondary nucleus and haploid male gamete. Therefore, if microspore mother cell has 2n= 24 chromosomes, the triploid endosperm will have 3n= 36 chromosomes.
