Describe the process of transpiration in vascular plants.

This is the diffusion (loss of water vapor) from the stomata (most cases) of a plant to its external environment.

It involves movement of water vapor down the water potential gradients; that is ; from higher water potential inside the leaf to lower water potential in the surrounding environments.

its cools the plant’s  internal temperature as  water vapour conveys heat out of  plants' cells.
