Q2. Solute and water potential are directly proportional
Q3. Hydrostatic pressure is usually positive
Q4.water potential is equal to solute potential Plus atmospheric pressure
Q5 non living components of xyleminvolved in apoplast pathway.
Q6. Guttation happens due to positive hydrostatic pressure in xylem
