IGCSE Biology Topic 3: Movement Into & Out of Cells | Diffusion, Osmosis & Active Transport Revision

Master Cambridge IGCSE Biology (0610) Topic 3: Movement Into and Out of Cells! In this rapid revision session, we break down the exact definitions, concentration gradients, mark-scheme keywords, and plant/animal cell effects for Diffusion, Osmosis, and Active Transport. 📥 DOWNLOAD THE FREE TOPIC 3 SUMMARY CHEAT SHEET & EXPERIMENTS GUIDE: [https://drive.google.com/file/d/1ARj5...] 💡 IN THIS VIDEO WE COVER: • Diffusion: Definition, factors affecting rate (surface area, temperature, distance, concentration gradient) • Osmosis: Water potential, partially permeable membranes, and net water movement • Effects of Osmosis on Animal Cells (Lysis vs. Crenation) • Effects of Osmosis on Plant Cells (Turgid, Turgor Pressure, Flaccid, Plasmolysis) • Active Transport: Moving against a concentration gradient using energy from respiration & protein carriers • All experiments including - Potato Cylinder experiments, Agar jelly block experiment & Dialysis Tubing experiment. • Past paper questions • Major Examiner Language Traps (Why you MUST write "water potential" instead of "water concentration") ⏰ TIMESTAMPS: 0:00 - Introduction & Topic 3 Overview 0:28 - Diffusion & Factors Affecting Rate 4:15 - Past paper questions on Diffusion 6:45 - Osmosis, (Turgidity vs. Plasmolysis) 11:38 - Past paper questions on Osmosis 15:20 - Active Transport 16:42- Comparison & Summary 17:56 - Past paper questions on Active Transport 19:48 - Outro 20.44 - Answers of Past Paper Questions. 🔗 RECOMMENDED VIDEOS TO WATCH NEXT: 1.
