State
A cell swelling past its membrane's capacity will lyse, or burst; one losing too much water will crenate, or shrink and shrivel.
Show
A red blood cell in pure water lyses within moments; one in a concentrated salt solution crenates instead.
Watch for
A mistakenly hypotonic or hypertonic IV solution can lyse or crenate blood cells by this mechanism.
