Let’s go step by step to match each cell picture (A–H) with the correct phase of mitosis and describe what’s happening.

We already know:
- Anaphase is labeled as H, and we’re told: “Chromosomes are pulled apart and begin moving to cell poles.” That matches image H — you can see chromosomes being pulled to opposite ends.

Now let’s look at each image one by one:

---

Image A:
You can see chromosomes scattered inside the nucleus, but they’re starting to condense. The nuclear envelope is still there, but spindle fibers are forming. This looks like Prometaphase — when the nuclear membrane breaks down and spindle fibers attach to chromosomes.

Wait — actually, in Prometaphase, the nuclear envelope disappears. In Image A, the nucleus seems intact? Let me check again.

Actually, looking closely:
In Image F, the nucleus is breaking down, chromosomes are visible, and spindle fibers are attaching — that’s more likely Prometaphase.

Let’s reorganize using standard mitosis order:

1. Interphase (1) – Cell is resting/preparing. DNA is not condensed. Nucleus is clear. → Looks like G
2. Prophase – Chromosomes condense, nucleus starts to break down, spindle forms. → F
3. Prometaphase – Nuclear envelope gone, spindle attaches to chromosomes. → A
4. Metaphase – Chromosomes line up in middle. → E
5. Anaphase – Chromosomes pulled apart. → H (already given)
6. Telophase – Two nuclei form, cell starts to pinch. → C
7. Cytokinesis – Cell splits into two. → B
8. Interphase (2) – Two new cells, each with own nucleus. → D

Wait — let’s double-check Image D: It shows two separate cells, each with a nucleus. That should be Interphase (2).

Image B: Two cells almost separated — that’s Cytokinesis.

Image C: Cell is pinching, two nuclei forming — that’s Telophase.

Image E: Chromosomes lined up in center — Metaphase.

Image A: Spindle fibers attached, chromosomes not yet aligned — Prometaphase.

Image F: Chromosomes condensing, nucleus still somewhat visible — Prophase.

Image G: One big nucleus, no chromosomes visible — Interphase (1).

Image H: Chromosomes pulling apart — Anaphase (given).

So now assign letters to phases:

- Interphase(1): G
- Prophase: F
- Prometaphase: A
- Metaphase: E
- Anaphase: H (given)
- Telophase: C
- Cytokinesis: B
- Interphase(2): D

Now write what’s happening for each:

- Interphase(1): Cell grows and copies its DNA. Everything is calm.
- Prophase: Chromosomes become visible, nucleus starts to disappear.
- Prometaphase: Nuclear membrane gone, spindle fibers grab chromosomes.
- Metaphase: Chromosomes line up in the middle of the cell.
- Anaphase: Chromosomes split and move to opposite sides.
- Telophase: Two new nuclei form, cell begins to pinch.
- Cytokinesis: Cell divides into two daughter cells.
- Interphase(2): Two new cells rest and prepare for next division.

Final matching:

Interphase(1) → G
Prophase → F
Prometaphase → A
Metaphase → E
Anaphase → H (given)
Telophase → C
Cytokinesis → B
Interphase(2) → D

──────────────────────────────────────

Final Answer:
Interphase(1): G — Cell grows and copies DNA; nucleus is intact.
Prophase: F — Chromosomes condense; nuclear envelope breaks down.
Prometaphase: A — Spindle fibers attach to chromosomes; no nucleus.
Metaphase: E — Chromosomes line up in the middle of the cell.
Anaphase: H — Chromosomes are pulled apart to opposite poles.
Telophase: C — Two nuclei form; cell begins to pinch.
Cytokinesis: B — Cell splits into two separate daughter cells.
Interphase(2): D — Two new cells rest; each has its own nucleus.
