What occurs when a cell is placed in a hypotonic solution?

When a cell is placed in a hypotonic solution, the concentration of solutes outside the cell is lower than that inside the cell. Consequently, water moves into the cell because water flows from areas of lower solute concentration to areas of higher solute concentration in an effort to equalize the concentrations on both sides of the cell membrane. In animal cells, this influx of water can lead to osmotic lysis, where the cell swells and potentially bursts if the pressure exceeds the membrane's capacity to hold. This is particularly relevant for animal cells, which lack a rigid cell wall that can help prevent bursting.

In contrast, plant cells in a hypotonic environment become turgid instead of bursting, due to their sturdy cell walls, which can withstand the internal pressure created by the excess water. While the correct answer indicates the effects on animal cells, it's important to remember that plant cells can handle such conditions differently due to their structural attributes. Thus, the movement of water and its consequences are key characteristics of how cells respond in a hypotonic solution.
