Transpiration is the loss of water from a plant in the form of water vapor. absorbed by roots from the soil and transported as a liquid to the leaves via xylem. leaves, small pores allow water to escape as a vapor. less than 5% remains in the plant for growth.
Water enters the root and is transported up to the leaves through specialized plant cells known as xylem (pronounces zigh-lem). Land plants must guard against drying out (desiccation) and so have evolved specialized structures known as stomata to allow gas to enter and leave the leaf.
