(1) Evaporation

(2) Transpiration

(3) Guttation

(4) Solarization

Following are some statements which ones are not incorrect?
a. Root pressure only provide a modest push in the overall process of water transport
b. Root Pressure obviously does not play a major role in water movement up tall trees
c. The greatest contribution of root pressure may be to re-establish the continuous chains of water molecules in the xylem which often break under the enormous tensions created by transpiration
d. Most of the plants meet their need by transpiratory pull
e. The exudate of guttation has pure water only
