Absence of air in the soil

Vedclass · Answer

(C) Water absorption occurs most efficiently in well-aerated soil.When soil is water-logged,the air spaces are filled with water,leading to a deficiency of $O_2$.This lack of $O_2$ inhibits the aerobic respiration of root cells.As a result,$CO_2$ accumulates in the roots,causing the protoplasm to become viscous and reducing the permeability of the plasma membrane.These physiological changes significantly decrease the rate of water and mineral absorption,eventually leading to the death of the plant.
