What is the significance of anaphase in relation to ploidy of an organism?
Anaphase is a critical stage of cell division, specifically during mitosis and meiosis, where sister chromatids or homologous chromosomes are pulled apart to opposite poles of the cell. This separation ensures that each daughter cell receives the correct number of chromosomes, maintaining the organism's ploidy level. In mitosis, the ploidy remains unchanged, resulting in two diploid daughter cells, while in meiosis, the reduction of chromosome number leads to haploid gametes, crucial for sexual reproduction. Thus, anaphase plays a vital role in ensuring genetic stability and variation within an organism's life cycle.
Is a change in ploidy always harmful to an organism?
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.

What is the ploidy of cells?
Human somatic cells are diploid, 2n. Human sex cells are haploid, n. Thus, the ploidy of human cells is 2, while n=23.
What is the ploidy of cells of aleurone layer in cereal grains?
The aleurone layer is the outermost layer of the endosperm. Therefore it is also triploid and same as the ploidy of endosperm.

What is the ploidy level of the micropyle?
The micropyle is a hole in the seed coat, it is literally nothing. Hence it is not made of cells and has no chromosomes.
