In which example in the table below will water move from X to Y by osmosis? Solute Concentration (%) Solution X Solution Y A. 3 8 B. 8 3 C. 3 1 D. 3 3 3. The diagram shows a visking tubing experiment involving sugar solutions of different concentrations.Solution R = 1% sucrose solution Solution S = 3% sucrose solutionThe experiments was left for 30 minutes.Predict the result of the experiment. A. C. 4. Water moves into the B. Water moves out of the bag and the contents of bag and the contents of the bag gain mass the bag lose mass Water moves out of the D. Water moves into the bag and the contents of bag and the contents of the bag gain mass the bag lose mass A plant cell, which was placed in a liquid, gained water by osmosis.When compared to the liquid, the cell contents are described as being A. plasmolysed B. hypertonic C. hypotonic D. flaccid 5. The diagram below shows the initial diameter of a potato disc. The potato disc was placed in a hypotonic solution for one hour. Which of the diagrams below correctly shows the change in the diameter of the disc? 6. A. B. C. D. Four thin sections of onion tissue were immersed in 5% sugar solution. The sections were left for 15 minutes then viewed under a microscope.The table below shows the percentage of cells plasmolysed in each section. A. 44 B. 50 C. 54 D. 200 7. A piece of potato was cut from a potato tuber and weighed. It was placed in pure water for one hour and then removed, dried and weighed again. Finally, it was placed in a concentrated sugar solution for an hour, removed, blotted dry and weighed again.Which line in the table records the results which would most likely be obtained? First Second Third Weighing Weighing Weighing A. 5g 6g 4g B. 5g 4g 6g C. 6g 5g 4g D. 5g 4g 3g 8. When animal cells are placed in a hypotonic solution they A. remain unchanged B. burst C. become turgid D. become plasmolysed 9. Four thin sections of red cabbage tissue were immersed in a 5% sugar solution.
