Question 7 • Chemistry A.1 - F26 - Jacob Metsker

Which describes a property of water that allows plants to transfer it from their roots to their leaves?

Answer
A
Water exhibits weak adhesion and cohesion, which allows capillary action to occur.
B
Water exhibits strong adhesion and cohesion, which allows capillary action to occur.
C
Water has low surface tension, which prevents capillary action from occurring.
D
Water has high surface tension, which prevents capillary action from occurring.

Explanation

Water molecules cohere to one another and adhere to the walls of the plant’s xylem. These strong attractions help water rise through narrow tubes by capillary action, aiding its movement from roots to leaves. Therefore, the correct choice is “Water exhibits strong adhesion and cohesion, which allows capillary action to occur.”
