(A) According to the passive absorption theory,the forces responsible for the absorption of water originate not in the cells of roots but in the cells of transpiring shoots.In this process,the root cells remain passive and do not expend metabolic energy $(ATP)$ to absorb water.Therefore,passive uptake of water does not require energy.
