Questions. (Answer 1-6 and the questions in your book 3, 5, 13, 20 and 23. 1. Why is the flow of water only ever one-way? 2. What is special about the membrane? 3. What key difference between salt and water does Osmosis rely on to work? 4. What is the name of the progress that Osmosis uses to get the water to flow from a region of high water concentration to low water concentration? 5. How does a plant get the water it needs? 6. How is osmosis important? Turgidity 7. Draw two diagrams below, one to show a plant that is very turgid and one that is wilting. Use arrows to show the direction of pressure and make sure you label everything. 8. Complete the sentences below: _________________ is the _________________ of water molecules from a region of higher water concentration to a region of _______________ water concentration through a _______________ ________________ membrane. A loss of cell ________________ can lead to wilting. ___________ is needed, along with carbon dioxide to make _____________ by photosynthesis. Plants lose water from their _________________ by ____________________. Plants get water from their __________________ by ____________________.
