isotonic, hypertonic, and hypotonic.

A hypotonic solution has a lower concentration of solutes than another solution. In biology, a solution outside of a cell is called hypotonic if it has a lower concentration of solutes relative to the cytosol. Due to osmotic pressure, water diffuses into the cell, and the cell often appears turgid, or bloated.

Hypertonic means that the environment outside of the cell has a higher concentration of solutes than the cell itself. That will attract water molecules from the cell leading to the shrinking of the cell.

Isotonic is a term used to describe solutions and chemistry and, sometimes, muscles in human biology. In chemistry, a solution is said to be isotonic when it has the same concentration of solutes as another solution across a semipermeable membrane.
