What would happen if a cell is placed in a hypotonic solution?

Plant cells placed in a relatively isotonic solution would not change in size; the exchange of water molecules in and out of the cell would be equal. Animal cells lack the strong cell wall, so they shrink in size when placed in a hypertonic solution, and will swell and may burst in a hypotonic solution.

Also to know is, when a cell is placed in a hypotonic solution?

When the plant cell is placed in a hypotonic solution , it takes up water by osmosis and starts to swell, but the cell wall prevents it from bursting. The plant cell is said to have become "turgid" i.e. swollen and hard. The pressure inside the cell rises until this internal pressure is equal to the pressure outside.

What is a hypotonic cell?

In a hypotonic solution the total molar concentration of all dissolved solute particles is less than that of another solution or less than that of a cell. If concentrations of dissolved solutes are less outside the cell than inside, the concentration of water outside is correspondingly greater.

Why do cells lyse in a hypotonic solution?

Water does this because, by diffusing to where there are more solutes, it essentially evens out the ratio of solvent and solute. When human cells are in a hypotonic solution, water will rush into the cell by osmosis, which is not good for the cell because it will fill with water and burst, or lyse.
