Mitosis in an Onion Cell - Free Printable

Looking at the image, we can see 22 numbered plant cells. Some of these cells show chromosomes (the dark, thread-like or X-shaped structures) inside them, while others do not.

The task is likely to count how many cells are in a specific stage of cell division — probably mitosis — since we’re seeing chromosomes visible in some cells.

Let’s go cell by cell and mark which ones clearly show chromosomes:

- Cell 1: Yes — chromosomes visible
- Cell 2: Yes — chromosomes inside dashed circle (likely prophase/metaphase)
- Cell 3: Yes — two sets of chromosomes (anaphase/telophase)
- Cell 4: No — nucleus present, no chromosomes
- Cell 5: No — nucleus present
- Cell 6: No — nucleus present
- Cell 7: Yes — two groups of chromosomes (anaphase)
- Cell 8: No — nucleus present
- Cell 9: Yes — two sets of chromosomes (anaphase/telophase)
- Cell 10: Yes — chromosomes visible
- Cell 11: No — nucleus present
- Cell 12: No — nucleus present
- Cell 13: No — nucleus present
- Cell 14: No — nucleus present
- Cell 15: Yes — chromosomes inside dashed circle
- Cell 16: No — nucleus present
- Cell 17: Yes — chromosomes visible
- Cell 18: Yes — two groups of chromosomes (anaphase)
- Cell 19: No — nucleus present
- Cell 20: No — nucleus present
- Cell 21: Yes — chromosomes inside dashed circle
- Cell 22: No — nucleus present

Now let’s count the “Yes” cells:

1, 2, 3, 7, 9, 10, 15, 17, 18, 21 → That’s 10 cells.

Wait — let me double-check:

List again:

✔ 1
✔ 2
✔ 3
✘ 4
✘ 5
✘ 6
✔ 7
✘ 8
✔ 9
✔ 10
✘ 11
✘ 12
✘ 13
✘ 14
✔ 15
✘ 16
✔ 17
✔ 18
✘ 19
✘ 20
✔ 21
✘ 22

That’s: 1,2,3,7,9,10,15,17,18,21 → 10 cells.

But wait — cell 3 shows two nuclei forming? Still counts as mitotic. Cell 7 same. Cell 9 same. All are in mitosis.

So total cells showing chromosomes = 10.

Final Answer:
10
