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 |
| :--- | :--- |
| **Purpose:** Growth, repair, and replacing cells | **Purpose:** Making gametes (sperm and egg cells) |
| **Where it happens:** Body cells | **Where it happens:** Reproductive organs (testes and ovaries) |
| **Divisions:** 1 cell division | **Divisions:** 2 cell divisions |
| **Daughter cells:** Produces 2 cells | **Daughter cells:** Produces 4 cells |
| **Chromosome number:** Diploid (full set / 46 in humans) | **Chromosome number:** Haploid (half set / 23 in humans) |
| **Variation:** Genetically identic…
| 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.*
