Transpiration

HideShow resource information

The movement of water in plants.

Transpiration is the loss of water vapour from the surface of the plant.

This water vapour is lost through the stomata on the lower surface of the leaf. They can open and close to let carbon dioxide into the plant. However, this means that water vapour can also escape at the same time.

The water vapour which is lost is replaces by water being pulled up through the xylem system through the roots.
