Answer

Soln:

Roots possess living cells that require oxygen for respiration and production of energy. These living cells absorb oxygen that is present in the spaces between soil particles. But in waterlogged soils, water occupies the spaces between soil particles and pushes the oxygen out into the atmosphere. Thus, roots are deprived of oxygen, and this affects root and plant growth.
