Question

What is the route of water in plants during transpiration?

Answer 1

When water evaporates through the leaves, a pull is created through the xylem, and water moves back to the leaves. This is known as the transpiration pull.

The ascent of sap that is driven by transpiration depends on the following properties of water:

1. Cohesion – This is the mutual attraction between molecules of water.
2. Adhesion – The attraction of water molecules towards polar surfaces.
3. Surface tension – The molecules of water are more attracted to each other in the liquid phase than in the gas phase
