Water Transport in Plants · NCERT Biology

Capillarity, the ability of water to rise in thin tubes, is aided by which characteristic of xylem elements?

  1. Large diameter of vessels allows fast bulk flow
  2. Small diameter of tracheary elements
  3. Presence of living protoplasts in mature vessels
  4. Thick secondary walls reinforced with lignin
Show answer and explanation

Correct answer: Small diameter of tracheary elements

Capillarity is the rise of liquids in narrow tubes. In plants, the small diameter of tracheids and vessel elements facilitates this upward movement through adhesive and cohesive forces.
