The small diameter of the tracheary elements increases ___________(a)

1.	The small diameter of the tracheary elements increases ___________(a) adhesion(b) cohesion(c) tensile strength(d) capillarityI have been asked this question in an online quiz.I need to ask this question from Transpiration topic in section Transport in Plants of Biology – Class 11
Answer» The correct option is (d) CAPILLARITY The EXPLANATION is: In plants, capillarity is aided by the small diameter of the xylem elements, i.e., the tracheids and vessel elements. Capillarity is the ability to RISE in thin tubes. Cohesion is mutual attraction between molecules of H2O. ADHESION is attraction of water molecules to the surfaces of tracheary elements. Tensile strength is ability to resist a pulling FORCE. Adhesion, cohesion and tensile strength are properties of xylem which enables the ascent of xylem sap.
