The pressure by which root hairs absorb water and minerals , from the soil, is
Open in App
Solution
The correct option is B DPD
Root cells behave as an ideal osmotic pressure system through which water moves up from the soil solution to the root xylum along an increasing gradient of D.P.D. (suction pressure, which is the real force for water absorption) along with water minerals and solutes also get get absorbed though sometimes at expense of ATP.So, the correct option is 'DPD'.
