🎓 IGCSE Biology - The Complete Course - https://www.tes.com/teaching-resource... • 🎓 IGCSE Chemistry - / igbiocomplete • ☕️ Buy me a coffee - https://www.buymeacoffee.com/ArthurJo... • Cambridge IGCSE Biology (0610/0970) • Chapter 17 - Inheritance • Topic 17.2 - Mitosis • Topic 17.3 - Meiosis • For exams in 2023, 2024 2025 (core and extended) • As always this video follows the Cambridge syllabus exactly and contains absolutely everything you need to know for your final exam! • My other channels: • @igpecompleteCambridge IGCSE PE • @ocrpecompleteOCR GCSE PE • Timestamps: • 0:00 Contents • 0:30 Mitosis • 1:00 Roles of mitosis • 1:22 Stem cells • 1:47 Meiosis • Mitosis and meiosis do not feature in the core syllabus. • Extended content: • Describe mitosis as nuclear division giving rise to genetically identical cells (details of the stages of mitosis are not required). • State the role of mitosis in growth, repair of damaged tissues, replacement of cells and asexual reproduction. • State that the exact replication of chromosomes occurs before mitosis. • State that during mitosis, the copies of chromosomes separate, maintaining the chromosome number in each daughter cell. • Describe stem cells as unspecialised cells that divide by mitosis to produce daughter cells that can become specialised for specific functions. • State that meiosis is involved in the production of gametes. • Describe meiosis as a reduction division in which the chromosome number is halved from diploid to haploid resulting in genetically different cells (details of the stages of meiosis are not required).
