A change in ploidy is not always harmful to an organism; it can sometimes be beneficial or neutral. For example, polyploidy, which is the condition of having more than two sets of chromosomes, is common in plants and can lead to increased vigor and adaptability. In some cases, organisms can tolerate or even thrive with changes in ploidy, while in others, it may disrupt normal development and function. Thus, the effects of ploidy changes depend on the specific organism and context.
In metaphase II, the ploidy of the cell is haploid because it has a single set of chromosomes. This is the result of the separation of sister chromatids in meiosis I, which reduces the chromosome number by half.

A zygote is a diploid
Human somatic cells are diploid, 2n. Human sex cells are haploid, n. Thus, the ploidy of human cells is 2, while n=23.
The aleurone layer is the outermost layer of the endosperm. Therefore it is also triploid and same as the ploidy of endosperm.
The micropyle is a hole in the seed coat, it is literally nothing. Hence it is not made of cells and has no chromosomes.
In metaphase II, the ploidy of the cell is haploid because it has a single set of chromosomes. This is the result of the separation of sister chromatids in meiosis I, which reduces the chromosome number by half.
