Phases of Mitosis Worksheet - Free Printable

Let’s go step by step to figure out which stage of mitosis each numbered cell is in.

We’re told:
- P = Prophase (used 2 times)
- M = Metaphase (used 3 times)
- A = Anaphase (used 3 times)
- T = Telophase (used 2 times)

That means we need to assign exactly:
→ 2 cells as Prophase
→ 3 cells as Metaphase
→ 3 cells as Anaphase
→ 2 cells as Telophase

Total: 10 cells — matches the numbers 1–10.

Now, let’s recall what each stage looks like in onion root tip cells (which are plant cells):

🔹 Prophase: Chromosomes become visible and start to condense. The nucleus may still be visible or breaking down. Cell looks “messy” inside with tangled threads.

🔹 Metaphase: Chromosomes line up in the middle (equator) of the cell. They look like a straight line across the center.

🔹 Anaphase: Sister chromatids are pulled apart toward opposite ends of the cell. You’ll see two groups of chromosomes moving away from each other.

🔹 Telophase: Two new nuclei are forming at opposite ends. The cell might start to pinch or form a cell plate (in plants). Chromosomes start to uncoil.

Now let’s examine each numbered cell one by one:

Cell 1: Chromosomes are lined up in the middle → Metaphase

Cell 2: Chromatids are being pulled apart — you can see them separating toward poles → Anaphase

Cell 3: Chromosomes are condensed but not yet aligned; nucleus seems to be disappearing → Prophase

Cell 4: Chromosomes are clearly lined up in the middle → Metaphase

Cell 5: Chromatids are separated and moving to opposite sides → Anaphase

Cell 6: Chromosomes are aligned in the middle → Metaphase

Cell 7: Two distinct groups of chromosomes at opposite ends; cell starting to divide → Telophase

Cell 8: Chromosomes are scattered, not aligned; looks early in division → Prophase

Cell 9: Chromatids are pulling apart — clear separation → Anaphase

Cell 10: Two nuclei forming at opposite ends; cell wall beginning to form between them → Telophase

Let’s count our assignments:

- Prophase: Cells 3, 8 → ✔ 2 total
- Metaphase: Cells 1, 4, 6 → ✔ 3 total
- Anaphase: Cells 2, 5, 9 → ✔ 3 total
- Telophase: Cells 7, 10 → ✔ 2 total

Perfect! Matches the required counts.
