True or False: An isotonic solution indicates the solute concentration is the same on either side of the cell membrane.

An isotonic solution indicates that the concentration of solute particles is equal on both sides of the cell membrane. In this state, there is no net movement of water into or out of the cell, allowing it to maintain its shape and physiological function effectively. Osmosis—the movement of water across a semi-permeable membrane—will be balanced, which is essential for the cells of both animals and plants to function without undergoing swelling or shriveling.

When a solution is isotonic in relation to a cell, it helps maintain homeostasis within that cell, preventing any detrimental effects that could arise from the imbalance of solute concentrations. This application is essential in various biological processes, including hydration and nutrient absorption.
