Vedclass · Answer

(B) Ascent of sap is the upward movement of water and dissolved minerals from the roots to the aerial parts of the plant. This process is primarily driven by the transpiration pull,which is a physical (passive) force generated by the evaporation of water from the leaves. Since it relies on the cohesion-tension mechanism and does not involve the metabolic activity of the plant to move water against gravity,it is considered a passive process. Therefore,there is no requirement for energy expenditure by the plants.
