A-Level Biology - Osmosis - Water Potential | Osmosis in Animal & Plant Cells (2026/27 exams)

⭐️ Check out our website https://www.cognito.org/ ⭐️ ** WHAT'S COVERED ** 1. Water Potential Explained Definition of water potential and its measurement in kilopascals (kPa). How solute concentration affects water potential. The relationship between high/low water potential and the concentration of water. 2. The Process of Osmosis Definition of osmosis as the net movement of water across a partially permeable membrane. Explanation of water moving down a water potential gradient until equilibrium is reached. 3. Effects of Osmosis on Cells How animal and plant cells react in hypotonic solutions (e.g., bursting and becoming turgid). The behaviour of cells in isotonic solutions where there is no net movement of water. How animal and plant cells react in hypertonic solutions (e.g., shrinking and plasmolysis). ** CHAPTERS ** 0:00 Introduction to Osmosis 0:21 What is Water Potential? 2:16 What is Osmosis? 3:27 How Osmosis Affects Animal and Plant Cells 3:46 Effects of Hypotonic Solutions on Cells 4:27 Effects of Isotonic Solutions on Cells 4:43 Effects of Hypertonic Solutions on Cells ** PLAYLISTS **    • KS3 Biology      • KS3 Chemistry      • KS3 Physics      • GCSE Maths (9-1)      • GCSE Biology (9-1)      • GCSE Chemistry (9-1)      • GCSE Physics (9-1)      • A-Level Biology   #alevel #Biology #study #revision #school #exam #AQA #OCR #Edexcel
