What is a characteristic of a hypotonic solution?

A hypotonic solution is characterized by having a lower concentration of solute compared to another solution. In biological terms, this often refers to a solution that surrounds cells. When cells are placed in a hypotonic solution, water moves into the cells to balance the solute concentrations. This can lead to swelling or even bursting of the cells if the difference in concentration is significant enough.

In the context of the options provided, the correct choice reflects the fundamental definition of a hypotonic solution. It is this less concentrated nature that defines it and distinguishes it from hypertonic or isotonic solutions. A hypotonic environment creates a specific osmotic pressure dynamic, essential for understanding various physiological processes, such as how cells maintain homeostasis and fluid balance.
