Question

What structures does water escape through during transpiration?

Answer 1

Transpiration produces a tension or pull on the water in the xylem vessels by the leaves. Water molecules are cohesive so water is pulled through the plant .

Answer 2

Transpiration produces a tension or 'pull' on the water in the xylem vessels by the leaves. Water molecules are cohesive so water is pulled up through the plant.
