An isotonic environment refers to a solution that has the same concentration of solutes as a reference solution or a cell. In other words, the concentration of solutes inside and outside the cell or in the surrounding environment is balanced. In this state, there is no net movement of water across the cell membrane, resulting in no change in cell volume. Isotonic environments are considered ideal for cell function because they maintain cellular homeostasis and prevent any adverse effects caused by osmosis, such as cell shrinkage or swelling.
An isotonic environment refers to a state where the osmotic pressure is equal on both sides of a membrane. In simpler terms, it means that the concentration of solutes (such as salts or ions) inside and outside of cells or a semi-permeable membrane is the same.
