Where they differed most

The task — Compare for the exam

Make a two-column comparison (markdown table, max 6 rows) of mitosis vs meiosis a GCSE student could memorise: chromosome number, divisions, daughter cells, variation, where it happens, purpose.

| **Mitosis** | **Meiosis** |
|---|---|
| **Chromosome number:** Same as parent cell (diploid, 2n) | **Chromosome number:** Half the parent cell’s number (haploid, n) |
| **Divisions:** One | **Divisions:** Two |
| **Daughter cells:** Two genetically identical cells | **Daughter cells:** Four genetically different cells |
| **Variation:** No genetic variation produced | **Variation:** Produces genetic variation |
| **Where it happens:** Body cells | **Where it happens:** Reproductive organs |
| **Purpose:** Growth, repair and replacing damaged…
| Feature | Mitosis | Meiosis |
|---|---|---|
| **Chromosome number** | Stays the same (46 → 46) | Halves (46 → 23) |
| **Divisions** | 1 | 2 |
| **Daughter cells** | 2 identical cells | 4 different cells |
| **Variation** | None – cells are clones | Yes – every cell is unique |
| **Where it happens** | All body cells | Ovaries and testes |
| **Purpose** | Growth and repair | Making gametes (sex cells) |

**Memory hook:** *Mi**t**osis makes **T**wo identical cells; Meiosis **M**ixes genes and **M**akes gametes.*
