There is a discrepancy in the reading I've done this morning. Some sources say guttation occurs whenever there is enough moisture to create root pressure. Transpiration is a physiological process. This is called as Guttation and takes place usually early in the morning when the rate of water absorption and the root pressure are higher while the transpiration is very low. (vi) It occurs through hydathodes. 6. Join the 2 Crores+ Student community now! More transpiration occurs from the upper surface of a leaf. Transpiration is the process of water movement through the plant and its subsequent evaporation through the leaves, stems and flowers. Therefore, the water potential inside the plant is very high. Caused by root pressure. 3. Takes place through the stomata. Water is lost in the form of vapors. VIEW SOLUTION. The fluid which oozes out in guttation contains a variety of dissolved inorganic and organic substances. 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.

TRANSPORT IN PLANTS 5555555555 6. 2 Water lost in guttation is rich in minerals. This is called as guttation and takes place usually early in the morning when the rate of absorption and root pressure are high while the transpiration is very low. 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. Class 12 Class 11 Class 10 Class 9 Class 8 Class 7 Class 6.
