Where they differed most
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 |
| Feature | Mitosis | Meiosis | |----------------------|----------------------------------|--------------------------------------| | Chromosome number | Same as parent (2n → 2n) | Halved (2n → n) | | Divisions | One | Two | | Daughter cells | 2 identical | 4 genetically different | | Variation | None (clones) | Yes…
