While looking at the root tip under a microscope, poke and tap at the root tip in the stain to make the cells of the root tip fall apart. 2. Do this sort of thing for about five minutes. Take time to make sure the root tip is really fragmented into tiny pieces. Add a little more stain if your root-tip starts to dry out. 3.The cell cycle. 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.
