While this is not necessarily one of the main stages of mitosis, cells in this state can easily be identified by their prominent nucleoli. Diagrammatic representation of an onion root tip cell during interphase:Diagrammatic representation of an onion root tip cell during interphase. Credit: ...
Studies of cells in interphase and prophase show that at all stages of the mitotic cycle in the nuclei of Einkorn wheat and onion root tips the arrangement of the chromosomes bears a definite relation to the axis of the nucleus. The establishment, by the centromeres, of the metaphase plate ...

Why do cells spend most of their life in interphase? What is difference of cell conditions between liver cells and onion root tips based on mitotic index of them? What causes the apical meristem to produce new cells? Why do cells divide? Why are animal cells more irregularly shaped than ...

About 1 – 2 mm length of root tip was cut, fixed in acetic alcohol, washed in ice cold water, hydrolyzed in warm 1 N HCl, stained with aceto-carmine and squashed on glass slide. For each treatment, about 3000 cells were scored and classified into interphase and normal or aberrant ...
with the conventional method.The data, in agreement with earlier results, show that the largest interphase nuclei in the root meristem have already completed their DNA-synthesis.The mean DNA-contents per set of chromatids at late interphase, prophase, and telophase, appeared to be virtually identic...
