A cell is placed in a solution, and over time, it begins to shrink. Which type of solution was the cell most likely placed in, and what caused this change?
Understand the Problem
The question is asking which type of solution caused a cell to shrink when placed in it, and it requires knowledge of osmosis and the effects of different types of solutions (isotonic, hypertonic, hypotonic) on cells.
Answer
Hypertonic solution; water moved out of the cell to balance solute concentration.
The final answer is Hypertonic solution; water moved out of the cell to balance solute concentration.
Answer for screen readers
The final answer is Hypertonic solution; water moved out of the cell to balance solute concentration.
More Information
In a hypertonic solution, the concentration of solutes is higher outside the cell. This causes water to leave the cell, resulting in the cell shrinking.
Tips
A common mistake is confusing hypertonic and hypotonic solutions. Remember, a hypertonic solution has a higher solute concentration outside the cell, causing water to move out.
