Both $(A)$ and $(B)$.

Vedclass · Answer

(C) Physiological drought occurs when water is present in the soil,but plants are unable to absorb it. When the water content in the soil is excessively high,it displaces air from the soil pores,leading to a deficiency of oxygen. In this condition,root cells cannot perform respiration,resulting in a lack of $ATP$ production. Due to the lack of energy,active absorption of water stops. Additionally,excessive water reduces the capillary force,which is essential for the movement of water to the roots. Therefore,despite the availability of water,the plant cannot absorb it.

$(1)$ High viscosity	$(a)$ Temperature of the environment does not affect water
$(2)$ Cohesion	$(b)$ Acts as an efficient solvent
$(3)$ High specific heat	$(c)$ Absorption of mechanical shocks
$(4)$ Polarity	$(d)$ Necessary for the ascent of sap in plants

From a physiological perspective,why does a high water content in soil particles lead to a dry process (physiological drought)?
