Question 2 • AP Biology - SC5182 A

Which of the following properties does NOT play a role in trees growing to towering heights by moving water from roots to leaves?

Answer
A
water forming hydrogen bonds with other water molecules
B
water forming hydrogen bonds with other substances like cell walls
C
water absorbing energy to change the state of matter from liquid to gas
D
water absorbing energy in large amounts to increase by a degree of temperature

Explanation

Water’s cohesion, from hydrogen bonds between water molecules, helps maintain an unbroken column as it moves upward through a tree. Its adhesion to cell walls also helps water climb through narrow vessels, and evaporation from leaves (liquid water changing to gas) helps pull more water upward. Water’s ability to absorb large amounts of energy before its temperature rises is not part of this transport mechanism, so the answer is water absorbing energy in large amounts to increase by a degree of temperature.
