The watery drops consist of water in which many inorganic and organic substances are dissolved. Transpiration is a physiological process. Guttation occurs because plant roots actively transport ions and other solutes to the xylem that conducts water up. The process of guttation takes place a. when the root pressure is high and the rate of transpiration is low. Guttation: Transpiration: Occurs early morning and at night. Simply put, dew is formed on the plant’s surface from the condensation of moisture in the air. • Guttation occurs through the hydathodes on leaf tips while transportation takes place mainly through stomata.
