Question
State the biological significance of the narrow xylem vessels in flowering plants
Answer
To sustain capillarity.
The narrow diameter of xylem vessels creates a capillary effect, also known as capillary action.
Capillarity is the ability of a liquid (in this case, water) to flow in narrow spaces, such as the thin tubes formed by the xylem vessels. This phenomenon is due to the cohesive and adhesive properties of water molecules.
