In eukaryotic cells, the cell cycle is divided into two major phases: interphase and mitosis (or the mitotic (M) phase). Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells.

In most biology labs, when learning about mitosis, we stain onion root tips in order to observe mitosis in plant cells and observe real tissue undergoing mitotic division. Watch the video linked below to learn about the root tip staining process.The percentage of time spent in each stage of the cell cycle = (total time in stage/total time). In conclusion, I have registered the peculiarities of mitosis processes in the onion root and whitefish blastula. The main difference is that in onion root cells - plant cells - there is no cleavage furrow forming due to the rigid cell wall.The onion root is also a good place because this is the area where the plant is growing. Remember that when cells divide, each new cell needs an exact copy of the DNA in the parent cell. This is why mitosis is only visible in cells that are dividing, like the whitefish embryo and the onion root tip. Mitosis can take several hours to complete.as the onion root tip cells, this is seen as the for-mation of a cell plate, dividing the original cell into two (presumably equivalent) daughter cells.
