1 Transport in Plants Easy

Match List-I with List-II

Pick the matching item from Column II for each row.
Column I
- A. Cohesion Match for A
- B. Adhesion Match for B
- C. Surface tension Match for C
- D. Guttation Match for D
Column II
- I. More attraction in liquid phase
- II. Mutual attraction among water molecules
- III. Water loss in liquid phase
- IV. Attraction towards polar surfaces
Correct answer: A → II, B → IV, C → I, D → III

Cohesion is mutual attraction of water molecules and adhesion is attraction to polar surfaces.

Cohesion: Mutual attraction between water molecules. Adhesion: Attraction of water molecules to polar surfaces. Surface Tension: Water molecules are attracted to each other in the liquid phase more than to water in the gas phase. Guttation: Water loss in its liquid phase near the tip of grass blades.
