Q.
Passive absorption of water is related to all, except
NTA AbhyasNTA Abhyas 2022
Solution:
Passive absorption is absorption by the pull from transpiration without the active involvement of the root cells. The whole root acts as a cell and the multicellular radicular tissue behaves as an osmotic membrane, establishing a positive hydrostatic pressure in the xylem responding to the accumulation of solutes. The development of positive pressure in the xylem is during imbibition and this is not related to the transpiration pull.
