The term for a solution in which the solute concentration is greater than that in the cell is called a hypertonic solution. In hypertonic environments, water moves out of the cell through osmosis, causing the cell to shrink or undergo crenation. This osmotic imbalance can significantly impact cellular processes, leading to loss of functionality and potential cell death. Understanding hypertonicity is crucial in fields such as cell biology and medicine, where it can influence treatments for various conditions and the preservation of biological samples.
