Vedclass · Answer

(D) Soil is considered physiologically dry when plants are unable to absorb water from the soil even if water is present. This occurs in two main scenarios: $1$. When the concentration of the soil solution is higher than the concentration inside the root cells (high salinity),which prevents water uptake via osmosis. $2$. When the soil temperature is $0^{\circ}C$,which reduces the permeability of root cell membranes and increases the viscosity of water,making absorption difficult. Therefore,both $(b)$ and $(c)$ lead to physiological dryness.
