If a plant cell loses water at the same rate that it takes in water, what type of solution is it in?
A
Hypertonic solution
B
Hypotonic solution
C
Supersaturated solution
D
Isotonic solution
Verified step by step guidance1
Understand the concept of tonicity: Tonicity refers to the relative concentration of solutes in a solution outside the cell compared to inside the cell. It determines the direction of water movement across the cell membrane.
Recall the definition of isotonic solution: An isotonic solution has the same concentration of solutes as the inside of the cell, resulting in no net movement of water into or out of the cell.
Analyze the problem: The question states that the plant cell loses water at the same rate it takes in water. This indicates that there is no net movement of water, which is characteristic of an isotonic solution.
Compare with other options: Hypertonic solutions cause water to move out of the cell, hypotonic solutions cause water to move into the cell, and supersaturated solutions are not relevant to tonicity.
Conclude that the correct answer is isotonic solution, as it matches the condition described in the problem where water movement is balanced.
