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.

| Feature | Mitosis | Meiosis |
|---|---|---|
| Chromosome number | Stays the same (diploid → diploid) | Halved (diploid → haploid) |
| Divisions | One | Two |
| Daughter cells | 2 genetically identical cells | 4 genetically different cells |
| Variation | Produces no genetic variation | Produces genetic variation |
| Where it happens | Body cells | Reproductive organs (ovaries and testes) |
| Purpose | Growth, repair, and asexual reproduction | Produces gametes for sexual reproduction |
