The water in the xylem cells of plants shows capillarity due to properties like ____. (A). surface tension (B). adhesive forces (C). cohesive forces (D). neutral pH Choose the correct answer from the options given below:
Options
- A(A), (B) and (D) only.
- B(A), (B) and (C) only.
- C(A), (B), (C) and (D).
- D(B), (C) and (D) only.
Correct answer
B. (A), (B) and (C) only.
Step-by-step solution
Capillarity in the xylem cells of plants is the ability of water to rise in thin tubes. This phenomenon depends mainly on three physical properties of water: Cohesion: The mutual attraction between water molecules. Adhesion: The attraction of water molecules to polar surfaces, such as the walls of the xylem vessels. Surface tension: The property by which water molecules are more attracted to each other in the liquid phase than in the gas phase. Neutral pH does not contribute to capillarity. Therefore, (A), (B), and
