More transpiration occurs from the upper surface of a leaf. Guttation: Transpiration: Occurs early morning and at night. Caused by root pressure. Guttation occurs because plant roots actively transport ions and other solutes to the xylem that conducts water up. Transpiration is the process of water movement through the plant and its subsequent evaporation through the leaves, stems and flowers. It occurs at vein-ends on the margin or tips of the leaves where hydathodes are present. Guttation definition is - the exudation of liquid water from the uninjured surface of a plant leaf. Guttation is a phenomenon by which xylem sap is exuded through the pores of the hydathodes in the leaves, as the result of root pressure. Transpiration is a controlled and regulated phenomenon.

Questions from Transport in Plants . Root hairs are the extensions of the outer epidermal cells of the root. Some sources say guttation occurs whenever there is enough moisture to create root pressure. Guttation: 1. Takes place through hydathodes. Guttation only takes place when the cell vacuole is completely filled, because the plant will always first replenish any water shortages in the plant cells. But Guttation takes place at the time of night when the temperature is low and cold. View All. True. Other sources say it occurs when the stoma are closed at night while the roots continue to take in water, that when the stoma are closed, transpiration can't occur so guttation takes place. The process takes place through hydathodes. Research suggests that guttation only occurs in well-watered plants. When the soil has high moisture content, the water enters the roots because the water potential of the roots is less than that in the soil. NCERT P Bahadur IIT-JEE Previous Year Narendra Awasthi MS Chauhan. If false rewrite the wrong statement in its correct form: Transpiration is a physiological process .
