Which describes a hypotonic environment/solution outside the cell?

• Too much water in the cell will cause the cell to burst - the percentage of water is higher outside the cell than inside the cell

• Too little water in the cell will cause the cell to shrink - the percentage of water is lower outside the cell than inside the cell

• Concentrations of water are equal inside and outside the cell

Which describes an isotonic environment?

• Too much water in the cell will cause the cell to burst - the percentage of water is higher outside the cell than inside the cell

• Too little water in the cell will cause the cell to shrink - the percentage of water is lower outside the cell than inside the cell

• Concentrations of water are equal inside and outside the cell
