Explanation:

1. Anaphase: Sister chromatids move apart during anaphase.
2. Prophase: Nucleolus fades in prophase as chromatin condenses.
3. Telophase: New nuclear membrane forms in telophase.
4. Telophase (animal cell): Cell membrane pinches in (cleavage furrow in animals, related to cytokinesis which can be associated with telophase in terms of cell - division end - stage).
5. Telophase: Chromosomes decondense in telophase.
6. Metaphase: Chromosomes at the equator in metaphase.
7. Prophase: Nuclear membrane fades in prophase.
8. Anaphase: Chromosomes move to poles in anaphase.
9. Metaphase: Sister chromatids line up at equator in metaphase.
10. Telophase (animal cell): Cleavage furrow (division furrow) appears in telophase (animal cell cytokinesis).
11. Prophase: Spindle forms in prophase.
12. Interphase: Chromosomes not visible (as chromatin) in interphase.
13. Telophase (plant cell): Cell plate forms in plant cell telophase.
14. Interphase (S - phase): Chromosomes replicated in S - phase (part of interphase).
15. Telophase: Reverse of prophase (e.g., decondensing chromosomes, nuclear membrane re - forming).
16. Cytokinesis: Daughter cells created during cytokinesis (the physical separation of cells after mitosis).
17. Anaphase: Centromeres divide and chromosomes move to poles in anaphase.
18. Prophase: Chromatin condenses to form chromosomes in prophase.
19. Centromere: Connects two sister chromatids.
20. Chromatid: Each individual chromosome in a pair connected by centromere.
21. Spindle fiber: Forms in prophase, along which chromosomes move.
22. Metaphase: Last phase sister chromatids are together (before anaphase separation).
23. Interphase: Non - dividing cells remain in interphase.
24. Spindle fiber: Produced when protein fibers radiate from centrioles (part of spindle formation).
25. Cell Plate: Forms in plant cell near end of telophase.
26. Interphase: Period of cell growth and development between mitotic divisions.
27. Interphase (S - phase): DNA replicates in S - phase (part of interphase).
