Detailed explanation-1: -Solutions that contain the same concentration of water and solutes as the cell cytoplasm are called isotonic solutions. Cells placed in an isotonic solution will neither shrink nor swell since there is no net gain or loss of water.

Detailed explanation-2: -Final answer: When the concentration of water and solutes on either side of the cell membrane is same, the solution is said to be isotonic.

Detailed explanation-3: -An isotonic solution is defined as two solutions of equal concentrations of solutes and water separated by a semipermeable membrane to allow water to move freely in and out of a cell.

Detailed explanation-4: -An isotonic solution refers to two solutions having the same osmotic pressure across a semipermeable membrane. This state allows for the free movement of water across the membrane without changing the concentration of solutes on either side.

Detailed explanation-5: -If two solutions have the same osmolarity, they are said to be isoosmotic.
