U2)Osmosis 0.0 / 5 ? BiologyCellular processesA2/A-levelAQA Created by: lieselb12Created on: 19-04-20 16:08 What is osmosis? Movement of water from high water potential to low water potential through a semi permeable membrane 1 of 10 What is the process and does it require energy? Passive + no energy required 2 of 10 What is the highest water potential? Zero 3 of 10 What is water with solutes in it in terms of water potential number? Minus number 4 of 10 Why does water struggle to get through the bilayer? It's dipolar 5 of 10 What is water's channel protein? Aquaporin 6 of 10 What are the 3 factors that affect it? Difference in concentration gradient + surface area +osmotic pathway length 7 of 10 What is isotonic? When 2 solutions have the same wp 8 of 10 What is it called when there are lots of solutes present so there's a low wp? Hypertonic 9 of 10 What is it called when there are little of solutes present so there's a high wp? Hypotonic 10 of 10
