3B.1 - 3B.5 Mitosis, Meiosis and Reproduction Bundle

Pearson Edexcel International A Level Biology Complete Bundle (WBI12)

• Designed for: Pearson Edexcel International A Level Biology
• Covers: Unit 2: Cells, Development, Biodiversity and Conservation (WBI12)
• Includes Topic 3B: Complete Cell Division & Reproduction Series (Specification Points 3B.1 – 3B.5)

This comprehensive 5-part PowerPoint teaching bundle includes clear, highly visual lesson slides, step-by-step process breakdowns, and exam-focused summaries covering the entire cell division, gamete specialization, and mammalian fertilisation sequence for Pearson Edexcel International A Level Biology.

Designed to save teachers hours of preparation time while delivering maximum clarity for students, this bundle provides a complete, structured pathway through Topic 3B. Learners are guided seamlessly from nuclear division and chromosome dynamics to gamete adaptations, the mechanisms preventing polyspermy, and the generation of genetic variation. Ideal for full classroom delivery, unit revision, independent study, and targeted exam preparation.

What’s Included in This Bundle:

• 3B.1 The Cell Cycle: Interphase (G1​,S,G2​), DNA replication, cell growth, and cytokinesis
• 3B.2 Mitosis: Step-by-step nuclear division stages (Prophase, Metaphase, Anaphase, Telophase) and biological significance in growth and repair
• 3B.3 Sexual Reproduction: Gamete formation, fertilisation mechanisms, and sources of genetic variation
• 3B.4 Gametes: Structure & Function: Adaptations of sperm cells and ovum (acrosome, zona pellucida, haploid nucleus, mitochondria)
• 3B.5 Fertilisation in Mammals: Sequential pathway of sperm entry, acrosome and cortical reactions, and polyspermy prevention
• Exam-Focused Support: Key terminology definitions, visual summaries, and mark scheme guidance across all 5 topics

Perfect for: Complete Topic 3B teaching, scheme-of-work delivery, intensive revision courses, tutoring, and structured exam prep.
