MyCompetitiveExams Dynamic 180-question full-length simulator mixed dynamically from all 6 years for 2027 & 2026 aspirants.
Match List I with List II. List I: A. Cohesion; B. Adhesion; C. Surface tension; D. Guttation. List II: I. More attraction in liquid phase; II. Mutual attraction among water molecules; III. Water loss in liquid phase; IV. Attraction towards polar surfaces. Choose the correct answer from the options given below:
Cohesion = Mutual attraction between water molecules (II). Adhesion = Attraction to polar surfaces like tracheids (IV). Surface tension = Greater attraction in liquid phase than gas (I). Guttation = Loss of liquid water droplets through hydathodes (III)!
Transpiration pull depends on three fundamental intermolecular properties of water:
Root pressure drives the exudation of water in the liquid phase through specialized hydathode pores at vein endings of leaves during nights or early mornings when transpiration is low:
Pairing A-II, B-IV, C-I, D-III perfectly matches Option (2).
Diagnose every choice: Know exactly why the right option works and why distractors fail.
Mismatches Adhesion with surface tension properties.
Verbatim alignment with NCERT physical definitions of cohesion, adhesion, surface tension, and guttation.
Scrambles all associations.
Mismatches cohesion with liquid loss.
Cohesion is attraction between like molecules (water-to-water). Adhesion is attraction between unlike molecules (water-to-polar cell wall surfaces).
"Cohesion is mutual attraction between water molecules; Adhesion is attraction to polar surfaces; Surface tension is greater attraction in liquid phase; Guttation is water loss in liquid phase."
