Alla uses a microscope to look at slides of onion cells. the slides show the stages of the cell cycle. the slides are labeled and in the correct order, starting with interphase. in which slide would alla first see chromosomes?

I'm pretty sure it's prophase because during the prophase the chromatin condenses into chromosomes. It might be metaphase as the DNA are already in the visible form; chromosomes. But that stage is mostly about the attachment of spindle fibres to the chromosomes.
