Question
Test your understanding of osmosis by predicting in each of the following cases whether water will center (IN) or leave cell (OUT), or whether there will be no net movement of water (NOTE). Assume that the cell membrane is permeable to water not solutes. Cell is exposed to hypertonic solution. Cell is placed in salt solution whose concentration is greater than cell contents. Due to disease, solute concentration of body fluid outside cell is less than solute concentration of cells. Cell is in isotonic solution. A Paramecium (a single-celled creature) is placed in a drop of pure water for examination under a microscope. Solute concentration of cell is greater than solute concentration of surrounding fluid. Cell is exposed to hypotonic solution. Concentration of solutes inside cell is equal to concentration of solutes outside of cell. Cytoplasm is more dilute than surrounding solution. Internal solute concentration of a cell is 45% while the concentration of solute outside of cell is 75%. Internal solute concentration of a cell is 80% while the concentration of solute outside of cell is 20%.Explanation / Answer
1-Out.
Water will move out of the cell when placed in hypertonic solution.
2. Out
Water will move out of the cell when olaced in salt solution with higher concentration than cell contents because outside solution will become hypertonic.
3. IN.
with lessser solute concentration, outside solution will become hypotonic and water will move into the cell.
4. NONE.
5.IN.
Pure water is hypotonic with respect to interior of the cell.
6. IN.
solute concentration greater inside cell means cell interiir is hypertonic with respect to outside.
7.IN.
8.NONE.
same concentration on both sides makes isotonic environment for the cell so there will be no net movement of water.
9.OUT.
More dilute cytoplasm means inside solution of the cell is hypotonic with large water content.
10.OUT.
11. IN.
