In a light microscope image of dividing onion root cells, you can identify different stages of the cell cycle by their characteristics. Interphase cells appear with a distinct nucleus and chromatin material. Prophase shows condensed chromosomes and the breakdown of the nuclear envelope. In metaphase, chromosomes align at the cell equator, while anaphase displays sister chromatids pulling apart. Telophase concludes with the reformation of the nuclear envelope around the separated chromosomes, leading to cytokinesis.

Chromosomes in onion cells are typically longer and have visible constrictions called centromeres, giving a beaded appearance. On the other hand, whitefish chromosomes are usually shorter and more rod-shaped without distinct centromeres. Additionally, onion chromosomes are usually larger in size compared to whitefish chromosomes.
