Is the environment established in beaker #1 containing the blue 20% sucrose cell hypotonic, isotonic or hypertonic? How were you able to determine this fact from your data? What is a possible outcome if this was a real, living cell in this type of environment? 11. What was the net change in mass over the 75-minute experimental period for cell #2? 12. Was this change significant compared with the others noted? Explain why or why not. 13. Is the environment established in thebeakercontainingcell #3 hypotonic, isotoni or hypertonic? How were you able to determine this fact from your data? 14· You filled each cell with 15 mL of solution. How many L is that?Explanation / Answer
10. The environment established in beaker #1 is hypotonic solution i.e it contains more number of water molecules than solute molecules whereas the environment inside cell#1 is hypertonic in nature i.e it contains less number of water molecules than solute molecules. So, there is a net movement of water molecules from their region of higher concentration to the region of lower concentration i.e from the beaker#1 to the cell #1resulting in a net gain of water molecules of the cell and further leads to a increase in the cell weight i.e from 29.53 to 36.79 over time.
The possible outcome would be that the cell would become turgid i.e it would swell if placed in such an environment.
