Which of the following best describes what happens when a bacterial cell is placed in a solution containing 5% NaCl?Group of answer choicesWater will move into the cell.Sucrose will move into the cell from a higher to a lower concentration.The cell will undergo osmotic lysis.Water will move out of the cell.No change will result; the solution is isotonic
Solution
The best description of what happens when a bacterial cell is placed in a solution containing 5% NaCl is that water will move out of the cell. This is due to the process of osmosis.
Here's a step-by-step explanation:
-
Osmosis is the movement of water from an area of lower solute concentration to an area of higher solute concentration through a semi-permeable membrane.
-
In this case, the 5% NaCl solution has a higher solute concentration than the inside of the bacterial cell.
-
Therefore, to balance the solute concentrations, water will move from inside the bacterial cell (where there is a lower solute concentration) to the outside (where there is a higher solute concentration).
-
This movement of water out of the cell can cause the cell to shrivel up in a process called plasmolysis.
So, the correct answer is "Water will move out of the cell."
