OUTSIDE EQUALS the concentration INSIDE a cellA. HYPOTONIC
______Describes a solution in which the solute concentration B. HYPERTONIC
OUTSIDE a cell IS LESS THAN the concentration INSIDE
C. ISOTONIC

in a plant cell when placed in a HYPERTONIC environment
B. PLASMOLYSIS
______The swelling and bursting of an animal cell when placed
in a HYPOTONIC solutionC. CYTOLYSIS
______The shrinking of animal cells when placed in an hypertonic solution
