Question

The column of water extending in tubes from plant roots to leaves is maintained by ____.  
A) hydrophilic interactions
B) ionic bonds
C) covalent bonds
D) hydrophobic interactions
E) cohesion between water molecules

Quizplus · Accepted Answer

The column of water in plant tubes is maintained by cohesion between water molecules, which allows for the upward movement of water from roots to leaves. This cohesion is due to hydrogen bonding between water molecules, which creates a continuous chain of water molecules from root to leaf.
