Answer:

Interphase - There are 3 subphases called - G1 , S and G2 . In these subphases, DNA material is duplicated, and essential proteins for cell division are formed.

Prophase - the nuclear envelop and nucleolus disappears and condensed DNA forms chromosomes that are short in size.

Metaphase - the form of two sister chromatids are arranged in the middle of the metaphase/equatorial line. Two centrioles are found at two poles of the cell which initiate the formation of spindle fibers.

Anaphase - spindle fibers are formed and can be observed. These fibres attach with the kinetochore present in the centromere of chromosomes and these chromatids now start separated by pulling and pushing force of spindle fibers in opposite poles

Telophase -  chromatids reach at destination pole and then nuclear envelop starts creating again in both poles. Nucleolus reappears and now in a cell two nucleus are found.
