Detailed explanation-1: -If a cell is in a hypertonic solution, the solution has a lower water concentration than the cell cytosol, and water moves out of the cell until both solutions are isotonic. Cells placed in a hypotonic solution will take in water across their membranes until both the external solution and the cytosol are isotonic.

Detailed explanation-2: -A cell placed into a hypotonic solution will swell and expand until it eventually burst through a process known as cytolysis.

Detailed explanation-3: -Endosmosis takes place when plant cell is immersed in hypotonic solution.

Detailed explanation-4: -For example, if the cells fluid has a higher osmolarity (concentration of solute), than the extracellular fluid, the fluid in the interior is hypertonic to the extracellular fluid, and the extrcellular fluid is hypotonic to the cell interior.

Detailed explanation-5: -When a cell is kept in hypertonic solution for a long time it shrinks. The water inside the cell moves out as the concentration outside the cell is higher. As a result, the cell shrinks. This is also known as plasmolysis.
