Explanation:

The cell cycle phases in mitosis include prophase (chromatin condenses into chromosomes, nuclear - envelope breaks down), metaphase (chromosomes line up at the equator), anaphase (sister chromatids separate and move to opposite poles), telophase (nuclear envelopes reform around the separated chromosomes), and cytokinesis (cytoplasm divides). By observing the position and state of chromosomes and the nuclear - envelope in each image, we can identify the phases.

Answer:

1. First image: Prophase (chromatin is condensing, nuclear - envelope visible but starting to break down)
2. Second image: Telophase (nuclear envelopes reforming around separated chromosomes at opposite poles)
3. Third image: Metaphase (chromosomes lined up at the cell's equator)
4. Fourth image: Interphase (cell is in a non - dividing state, normal nucleus visible)
5. Fifth image: Metaphase (chromosomes aligned at the equatorial plate)
6. Sixth image: Anaphase (sister chromatids are separating and moving to opposite poles)
7. Seventh image: Cytokinesis (cytoplasm is dividing, two daughter cells are forming)
8. Eighth image: Anaphase (chromosomes are moving to opposite poles)
9. Ninth image: Prophase (chromatin is condensing into visible chromosomes)
