IB Biology HL 2.3.7 Medical applications Question Bank

a. isotonic is same water potential/solute potential/osmotic potential/solute concentration;

b. (isotonic conditions) prevent (net) movement of water by osmosis;

c. hypotonic plasma/tissue fluid causes water entry to blood/body cells;

d. swelling/bursting of cells in (hypotonic plasma/tissue fluid);

e. hypertonic plasma/tissue fluid causes water to exit cells;

f. shrinkage/crenation/loss of volume/OWTTE;

g. blood cells bathed in plasma;

h. tissue fluid released by capillaries and then reabsorbed/flows between cells in tissues;

In mark point c and mark point e

Marking guidance:

accept 'higher/less negative
water potential' instead of
hypotonic and accept
'lower/more negative water
potential’ instead of hypertonic.
