1.	Ascent of sap is possible due to some physical forces . How ?
Answer» Yes ascent of sap can take place due to some forces. As we know that water is absorbed by roots by Imbibtion, osmosis,etc it passes to root cortex by osmosis. This absorbed water rises upwards by Caparlity, root pressure,DPD,etc. It is furder supported by transpirational pull. All these Forces act as driving for forces for the ascent of sap
