The attraction between water molecules and cell wall of xylem is termed as :
Correct answer: A. Adhesion
- A. Adhesion
- B. Cohesion
- C. Capillary action
- D. Transpiration
Explanation
This is the correct answer. Adhesion refers to the attraction between molecules of different substances. In the case of xylem, the water molecules are attracted to the cellulose molecules in the cell walls. This adhesive force helps to pull water up the xylem vessels from the roots to the leaves.

About Plant Nutrition and Transport
Plants require macronutrients and micronutrients for growth, and mineral deficiencies produce recognizable symptoms. Transport involves water and minerals through xylem by transpiration pull, cohesion and adhesion, while phloem translocates sugars from sources to sinks. Root pressure and transpiration are distinct mechanisms.
