Which of the following statement is correct concerning the flow of sap in xylem of trees ?A. In the morning, sap begins to flow first in twigs and later in trunkB. Flow is driven by high concentration of sugars in the vessel elementsC. Flow from the roots to the twigs would be accelerated if the leaves are removedD. Rapid flow of water puts the xylem under a pressure much greater than atmospheric pressure
