Describe briefly the three physical properties of water which help in the ascent of water in xylem.
Answers (1)
Ans.
- Cohesion is the ability by which water molecules stick to each other, which helps the ascent of water in a continuous stream.
- Adhesion helps the ascent of water in the xylem as this is the ability by which water sticks to a surface causing easy transport.
- Surface tension helps the ascent of water in the xylem as this helps the water molecules to occupy the least surface area possible and helps in the maximum amount to move.
