How does an organism use tonicity to maintain homeostasis?


-Allows water to flow into a cell when the cell is placed in a hypertonic solution to become isotonic.

-Allows water to flow into a cell when the cell is placed in a hypotonic solution so the cell becomes hypotonic.


-Allows water to leave a cell when the cell is placed in a hypotonic solution to become isotonic
