Transpiration

How plants transport moisture from their roots to small holes located on the leaf undersides, converting to vapor and then releasing it into the atmosphere.

Xylem

The vascular tissue in plants that conducts water and dissolved nutrients from the roots to the rest of the plant.

Phloem

The portion of a plant's vascular system responsible for transporting sugars and other metabolic products downward from the leaves.
