उत्तर
Following are the three physical properties of water that help in the ascent of water in the xylem.
- Cohesion: It is the ability of water molecules to stick to each other.
- Adhesion: It is the ability of water molecules to stick to a surface.
- Surface Tension: The property of any liquid that tends to occupy the smallest possible surface area is called surface tension. Water makes a continuous column of water in the xylem vessels by adhesion cohesion and surface tension. Transpiration pull pulls this water as a column.
