A zygote is a diploid
Endosperm of gymnosperm is haploid(ploidy n), develop from megaspore (n) before fertilization. ploidy of endosperm in angiosperm is 3n(central cell fused with one male gamete i.e 2n+n).
The micropyle is a hole in the seed coat, it is literally nothing. Hence it is not made of cells and has no chromosomes.
Generally, a somatic cell in a human body has 46 chromosomes, which are two complete sets of 23 chromosome pairs. Because they have two sets, these cells have a ploidy level of diploid.
DNA content is halved in both meiosis I and meiosis II. Ploidy level changes from diploid to haploid in meiosis I, and remains haploid in meiosis II.
Ploidy refers to the number of sets of chromosomes in an organism. The ploidy of animal cells that are capable of meiosis is diploid.
Mmc's=16 as its diploidendosperm=48 as it is triploid 3n
